# Touchscreen Calibration
|
||||
|
||||
The DReader HAL includes touchscreen calibration support to accurately align touch coordinates with display pixels. This is essential for precise touch interaction on e-ink devices.
|
||||
|
||||
## Why Calibration is Needed
|
||||
|
||||
Touchscreen controllers and display controllers are separate components with their own coordinate systems. Without calibration:
|
||||
|
||||
- Touch coordinates may not align precisely with display pixels
|
||||
- Touches may register at offset positions
|
||||
- The offset may vary across different areas of the screen
|
||||
- Linear scaling alone may not account for rotation, skew, or non-linear distortion
|
||||
|
||||
Calibration solves this by computing an **affine transformation matrix** that maps touch coordinates to display coordinates with high precision.
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Run Calibration
|
||||
|
||||
```bash
|
||||
cd examples
|
||||
python3 calibrate_touch.py
|
||||
```
|
||||
|
||||
This will:
|
||||
1. Display calibration targets (circles) at known positions
|
||||
2. Wait for you to touch each target
|
||||
3. Compute the transformation matrix
|
||||
4. Save calibration data to `~/.config/dreader/touch_calibration.json`
|
||||
|
||||
### 2. Use Calibrated Touch
|
||||
|
||||
Once calibration is complete, the touch driver automatically loads and applies the calibration:
|
||||
|
||||
```python
|
||||
from dreader_hal.touch.ft5xx6 import FT5xx6TouchDriver
|
||||
|
||||
touch = FT5xx6TouchDriver(width=800, height=1200)
|
||||
await touch.initialize() # Automatically loads calibration
|
||||
|
||||
# All touch events are now calibrated
|
||||
event = await touch.get_touch_event()
|
||||
print(f"Touch at ({event.x}, {event.y})") # Calibrated coordinates
|
||||
```
|
||||
|
||||
## Calibration Options
|
||||
|
||||
### Number of Calibration Points
|
||||
|
||||
You can choose between 5-point or 9-point calibration:
|
||||
|
||||
```bash
|
||||
# 5-point calibration (corners + center) - faster
|
||||
python3 calibrate_touch.py --points 5
|
||||
|
||||
# 9-point calibration (3x3 grid) - more accurate (default)
|
||||
python3 calibrate_touch.py --points 9
|
||||
```
|
||||
|
||||
**Recommendation:** Use 9-point calibration for best accuracy.
|
||||
|
||||
### Custom Calibration File Location
|
||||
|
||||
```bash
|
||||
python3 calibrate_touch.py --output /path/to/calibration.json
|
||||
```
|
||||
|
||||
Then specify the same path when initializing the touch driver:
|
||||
|
||||
```python
|
||||
touch = FT5xx6TouchDriver(
|
||||
calibration_file="/path/to/calibration.json"
|
||||
)
|
||||
```
|
||||
|
||||
### Display Dimensions
|
||||
|
||||
If your display is not the default 800x1200:
|
||||
|
||||
```bash
|
||||
python3 calibrate_touch.py --width 1024 --height 768
|
||||
```
|
||||
|
||||
## Testing Calibration
|
||||
|
||||
Use the test script to verify calibration quality:
|
||||
|
||||
```bash
|
||||
python3 test_calibration.py
|
||||
```
|
||||
|
||||
This displays an interactive UI where you can:
|
||||
- Tap anywhere on the screen
|
||||
- See calibrated coordinates with crosshairs
|
||||
- View calibration offset and error
|
||||
- Verify calibration quality
|
||||
|
||||
## Calibration Quality
|
||||
|
||||
The calibration system computes **RMS (Root Mean Square) error** to assess quality:
|
||||
|
||||
| Quality | RMS Error | Description |
|
||||
|---------|-----------|-------------|
|
||||
| Excellent | < 5 pixels | Professional-grade accuracy |
|
||||
| Good | 5-10 pixels | Suitable for most applications |
|
||||
| Fair | 10-20 pixels | Acceptable for basic touch |
|
||||
| Poor | > 20 pixels | Re-calibration recommended |
|
||||
|
||||
Quality is displayed during calibration and can be checked programmatically:
|
||||
|
||||
```python
|
||||
quality = touch.calibration.get_calibration_quality()
|
||||
error = touch.calibration.calibration_data.rms_error
|
||||
print(f"Calibration: {quality} ({error:.2f}px RMS error)")
|
||||
```
|
||||
|
||||
## How Calibration Works
|
||||
|
||||
### 1. Calibration Point Collection
|
||||
|
||||
The calibration process displays targets at known display coordinates and records the raw touch coordinates when you tap each target:
|
||||
|
||||
```
|
||||
Display Coordinates Touch Coordinates
|
||||
(100, 100) → (95, 103)
|
||||
(400, 100) → (392, 105)
|
||||
(700, 100) → (689, 107)
|
||||
...
|
||||
```
|
||||
|
||||
### 2. Affine Transformation
|
||||
|
||||
An affine transformation maps touch coordinates to display coordinates:
|
||||
|
||||
```
|
||||
x_display = a * x_touch + b * y_touch + c
|
||||
y_display = d * x_touch + e * y_touch + f
|
||||
```
|
||||
|
||||
This handles:
|
||||
- **Translation** (offset)
|
||||
- **Scaling** (different resolutions)
|
||||
- **Rotation** (if display is rotated)
|
||||
- **Skew** (non-perpendicular axes)
|
||||
|
||||
### 3. Least-Squares Fitting
|
||||
|
||||
The calibration algorithm uses **least-squares fitting** to find the best transformation matrix that minimizes error across all calibration points.
|
||||
|
||||
With N calibration points, the system is:
|
||||
- **Over-determined** (N > 3 points for 6 unknowns)
|
||||
- **Robust** to individual touch errors
|
||||
- **Optimal** in the least-squares sense
|
||||
|
||||
### 4. Coordinate Transformation
|
||||
|
||||
Once calibrated, all touch coordinates are automatically transformed:
|
||||
|
||||
```python
|
||||
# Raw touch from sensor
|
||||
raw_x, raw_y = 392, 105
|
||||
|
||||
# Apply calibration
|
||||
calibrated_x, calibrated_y = calibration.transform(raw_x, raw_y)
|
||||
# Result: (400, 100) - matches display target!
|
||||
```
|
||||
|
||||
## Calibration Data Format
|
||||
|
||||
Calibration is saved as JSON:
|
||||
|
||||
```json
|
||||
{
|
||||
"points": [
|
||||
{"display_x": 100, "display_y": 100, "touch_x": 95, "touch_y": 103},
|
||||
{"display_x": 400, "display_y": 100, "touch_x": 392, "touch_y": 105},
|
||||
...
|
||||
],
|
||||
"matrix": [1.05, -0.02, -3.5, 0.01, 0.98, 2.1],
|
||||
"width": 800,
|
||||
"height": 1200,
|
||||
"rms_error": 3.42
|
||||
}
|
||||
```
|
||||
|
||||
- **points**: List of calibration point pairs
|
||||
- **matrix**: Affine transformation `[a, b, c, d, e, f]`
|
||||
- **width/height**: Display dimensions
|
||||
- **rms_error**: Quality metric in pixels
|
||||
|
||||
## Programmatic Usage
|
||||
|
||||
### Manual Calibration
|
||||
|
||||
You can implement custom calibration UI:
|
||||
|
||||
```python
|
||||
from dreader_hal.calibration import TouchCalibration
|
||||
|
||||
# Create calibration instance
|
||||
calibration = TouchCalibration(width=800, height=1200, num_points=9)
|
||||
|
||||
# Generate target positions
|
||||
targets = calibration.generate_target_positions(margin=100, target_radius=20)
|
||||
|
||||
# For each target
|
||||
for display_x, display_y in targets:
|
||||
# Show target on display
|
||||
# Wait for touch
|
||||
touch_x, touch_y = get_touch() # Your touch reading code
|
||||
|
||||
# Add calibration point
|
||||
calibration.add_calibration_point(display_x, display_y, touch_x, touch_y)
|
||||
|
||||
# Compute transformation
|
||||
success = calibration.compute_calibration()
|
||||
|
||||
if success:
|
||||
# Save calibration
|
||||
calibration.save("~/.config/dreader/touch_calibration.json")
|
||||
|
||||
print(f"Quality: {calibration.get_calibration_quality()}")
|
||||
print(f"RMS Error: {calibration.calibration_data.rms_error:.2f}px")
|
||||
```
|
||||
|
||||
### Using Calibration
|
||||
|
||||
```python
|
||||
from dreader_hal.calibration import TouchCalibration
|
||||
|
||||
# Load existing calibration
|
||||
calibration = TouchCalibration(width=800, height=1200)
|
||||
calibration.load("~/.config/dreader/touch_calibration.json")
|
||||
|
||||
# Transform coordinates
|
||||
display_x, display_y = calibration.transform(raw_x, raw_y)
|
||||
|
||||
# Check if calibrated
|
||||
if calibration.is_calibrated():
|
||||
print("Calibration active")
|
||||
```
|
||||
|
||||
## When to Re-Calibrate
|
||||
|
||||
You should re-calibrate if:
|
||||
|
||||
- **Initial setup**: First time using the device
|
||||
- **Hardware changes**: Replaced touchscreen or display
|
||||
- **Poor accuracy**: RMS error > 20 pixels
|
||||
- **Display rotation**: Changed from portrait to landscape
|
||||
- **Physical damage**: Screen damage or loose connections
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Calibration Fails to Compute
|
||||
|
||||
**Problem:** `compute_calibration()` returns `False`
|
||||
|
||||
**Solutions:**
|
||||
- Ensure at least 3 calibration points were collected
|
||||
- Check that points are not all collinear
|
||||
- Verify touch coordinates are valid
|
||||
|
||||
### Poor Calibration Quality
|
||||
|
||||
**Problem:** High RMS error or "Poor" quality rating
|
||||
|
||||
**Solutions:**
|
||||
- Re-run calibration, touching targets more precisely
|
||||
- Use 9-point calibration instead of 5-point
|
||||
- Check for hardware issues (loose connections, damaged screen)
|
||||
- Ensure targets are clearly visible on e-ink display
|
||||
|
||||
### Calibration Not Loading
|
||||
|
||||
**Problem:** "No calibration file found" message
|
||||
|
||||
**Solutions:**
|
||||
- Check calibration file exists at expected path
|
||||
- Verify file permissions are readable
|
||||
- Ensure display dimensions match calibration data
|
||||
|
||||
### Touches Still Offset After Calibration
|
||||
|
||||
**Problem:** Calibrated touches don't align with targets
|
||||
|
||||
**Solutions:**
|
||||
- Check calibration quality with `test_calibration.py`
|
||||
- Re-run calibration
|
||||
- Verify calibration file is being loaded (check console output)
|
||||
- Ensure touch driver is using calibration (not bypassed)
|
||||
|
||||
## Advanced Topics
|
||||
|
||||
### Custom Transformation Algorithms
|
||||
|
||||
The default calibration uses affine transformation with least-squares fitting. For advanced use cases, you can extend `TouchCalibration`:
|
||||
|
||||
```python
|
||||
class CustomCalibration(TouchCalibration):
|
||||
def compute_calibration(self) -> bool:
|
||||
# Implement custom algorithm
|
||||
# e.g., polynomial transformation, neural network, etc.
|
||||
pass
|
||||
```
|
||||
|
||||
### Multi-Display Support
|
||||
|
||||
For devices with multiple displays:
|
||||
|
||||
```python
|
||||
# Calibration per display
|
||||
calibration_main = TouchCalibration(800, 1200)
|
||||
calibration_main.load("main_display_cal.json")
|
||||
|
||||
calibration_secondary = TouchCalibration(400, 600)
|
||||
calibration_secondary.load("secondary_display_cal.json")
|
||||
```
|
||||
|
||||
### Runtime Calibration Adjustment
|
||||
|
||||
You can update calibration without full re-calibration:
|
||||
|
||||
```python
|
||||
# Add new calibration points to existing calibration
|
||||
calibration.add_calibration_point(x_display, y_display, x_touch, y_touch)
|
||||
calibration.compute_calibration() # Re-compute with new points
|
||||
calibration.save(calibration_file)
|
||||
```
|
||||
|
||||

|
||||
## Key Design Decisions
|
||||
|
||||
1. **Polling Mode**: All sensors use polling (no interrupts) for simplicity and consistency
|
||||
2. **Async/Await**: All I/O operations are async for non-blocking execution
|
||||
3. **Thread Pool**: Blocking hardware operations run in thread pool
|
||||
4. **Virtual Display**: Tkinter-based testing without hardware
|
||||
5. **Optional Components**: Can disable RTC, orientation, power monitor
|
||||
6. **Modular**: Each driver is independent and testable
|
||||
7. **Spec Compliant**: Follows HAL Implementation Specification exactly
|
||||
|
||||
## Performance Characteristics
|
||||
|
||||
| Operation | Target | Actual |
|
||||
|-----------|--------|--------|
|
||||
| Display fast refresh | < 200ms | ~200ms (DU mode) |
|
||||
| Display quality refresh | < 1000ms | ~1000ms (GC16) |
|
||||
| Touch event latency | < 50ms | ~10ms (100Hz polling) |
|
||||
| Gesture detection | < 50ms | ~10-50ms |
|
||||
| Battery read | < 100ms | ~50ms |
|
||||
|
||||

## Installation Steps
|
||||
|
||||
### 1. Install External Drivers
|
||||
|
||||
The HAL depends on external driver libraries in the `external/` directory. These need to be installed first.
|
||||
|
||||
#### IT8951 (E-ink Display)
|
||||
```bash
|
||||
cd external/IT8951
|
||||
pip install ./[rpi] # On Raspberry Pi
|
||||
# OR
|
||||
pip install ./ # On desktop (virtual display only)
|
||||
cd ../..
|
||||
```
|
||||
|
||||
**Note**: IT8951 has Cython extensions that need to be compiled. Make sure you have `python3-dev` installed.
|
||||
|
||||
#### PyFTtxx6 (Touch Controller)
|
||||
```bash
|
||||
cd external/PyFTtxx6/pyft5xx6
|
||||
pip install -e .
|
||||
cd ../../..
|
||||
```
|
||||
|
||||
#### PyBMA400 (Accelerometer)
|
||||
```bash
|
||||
cd external/PyBMA400
|
||||
pip install -e .
|
||||
cd ../..
|
||||
```
|
||||
|
||||
#### PyPCF8523 (RTC)
|
||||
```bash
|
||||
cd external/PyPCF8523
|
||||
pip install -e .
|
||||
cd ../..
|
||||
```
|
||||
|
||||
#### pi_ina219 (Power Monitor)
|
||||
```bash
|
||||
cd external/pi_ina219
|
||||
pip install .
|
||||
cd ../..
|
||||
```
|
||||
|
||||
### 2. Install DReader HAL
|
||||
|
||||
```bash
|
||||
# Install in development mode
|
||||
pip install -e .
|
||||
|
||||
# Or install for Raspberry Pi with GPIO support
|
||||
pip install -e .[rpi]
|
||||
```
|
||||
|
||||
### 3. Verify Installation
|
||||
|
||||
```bash
|
||||
# Run tests
|
||||
pytest tests/
|
||||
|
||||
# Try example (virtual display, no hardware)
|
||||
python examples/simple_display.py
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### IT8951 Build Errors
|
||||
|
||||
If you get Cython build errors:
|
||||
|
||||
```bash
|
||||
# Install build dependencies
|
||||
sudo apt-get install python3-dev gcc
|
||||
|
||||
# Try installing with verbose output
|
||||
pip install -v ./external/IT8951/[rpi]
|
||||
```
|
||||
|
||||
### I2C Device Not Found
|
||||
|
||||
```bash
|
||||
# Check I2C devices
|
||||
i2cdetect -y 1
|
||||
|
||||
# Add user to i2c group
|
||||
sudo usermod -a -G i2c $USER
|
||||
# Log out and back in
|
||||
```
|
||||
|
||||
### Permission Denied
|
||||
|
||||
```bash
|
||||
# Add user to necessary groups
|
||||
sudo usermod -a -G spi,gpio,i2c $USER
|
||||
|
||||
# Reboot
|
||||
sudo reboot
|
||||
```
|
||||
|
||||
### Import Errors
|
||||
|
||||
If you get import errors, make sure all external drivers are installed:
|
||||
|
||||
```bash
|
||||
# Check installations
|
||||
pip list | grep -E "(IT8951|pyft5xx6|pybma400|pypcf8523|ina219)"
|
||||
```
|
||||
|
||||
## Development Setup
|
||||
|
||||
For development with testing and linting tools:
|
||||
|
||||
```bash
|
||||
# Install development dependencies
|
||||
pip install -r requirements-dev.txt
|
||||
|
||||
# Run tests with coverage
|
||||
pytest --cov=dreader_hal tests/
|
||||
|
||||
# Format code
|
||||
black src/ tests/ examples/
|
||||
|
||||
# Type checking
|
||||
mypy src/
|
||||
```
|
||||
|
||||
## Testing Without Hardware
|
||||
|
||||
To test the HAL without actual hardware:
|
||||
|
||||
```python
|
||||
from dreader_hal import EReaderDisplayHAL
|
||||
|
||||
# Create HAL with virtual components
|
||||
hal = EReaderDisplayHAL(
|
||||
virtual_display=True, # Tkinter window
|
||||
enable_orientation=False, # No accelerometer
|
||||
enable_rtc=False, # No RTC
|
||||
enable_power_monitor=False, # No INA219
|
||||
)
|
||||
```
|
||||
|
||||
This will use a Tkinter window for the display and won't try to access I2C devices.
|
||||
|
||||
## Quick Install Script
|
||||
|
||||
For convenience, here's a script to install everything:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# install_all.sh
|
||||
|
||||
set -e
|
||||
|
||||
echo "Installing external drivers..."
|
||||
|
||||
# IT8951
|
||||
cd external/IT8951
|
||||
pip install ./[rpi]
|
||||
cd ../..
|
||||
|
||||
# PyFTtxx6
|
||||
cd external/PyFTtxx6/pyft5xx6
|
||||
pip install -e .
|
||||
cd ../../..
|
||||
|
||||
# PyBMA400
|
||||
cd external/PyBMA400
|
||||
pip install -e .
|
||||
cd ../..
|
||||
|
||||
# PyPCF8523
|
||||
cd external/PyPCF8523
|
||||
pip install -e .
|
||||
cd ../..
|
||||
|
||||
# pi_ina219
|
||||
cd external/pi_ina219
|
||||
pip install .
|
||||
cd ../..
|
||||
|
||||
echo "Installing dreader-hal..."
|
||||
pip install -e .[rpi]
|
||||
|
||||
echo "Installation complete!"
|
||||
echo "Run 'pytest tests/' to verify."
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Quick Start
|
||||
|
||||
### Basic Usage
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from dreader_hal import EReaderDisplayHAL, GestureType
|
||||
from PIL import Image
|
||||
|
||||
async def main():
|
||||
# Create HAL
|
||||
hal = EReaderDisplayHAL(
|
||||
width=800,
|
||||
height=1200,
|
||||
vcom=-2.0, # Check your device label
|
||||
virtual_display=False, # Set True for testing
|
||||
)
|
||||
|
||||
# Initialize
|
||||
await hal.initialize()
|
||||
|
||||
# Display an image
|
||||
image = Image.open("my_page.png")
|
||||
await hal.show_image(image)
|
||||
|
||||
# Handle touch events
|
||||
while True:
|
||||
event = await hal.get_touch_event()
|
||||
|
||||
if event:
|
||||
if event.gesture == GestureType.SWIPE_LEFT:
|
||||
print("Next page!")
|
||||
elif event.gesture == GestureType.SWIPE_RIGHT:
|
||||
print("Previous page!")
|
||||
elif event.gesture == GestureType.TAP:
|
||||
print(f"Tapped at ({event.x}, {event.y})")
|
||||
|
||||
# Cleanup
|
||||
await hal.cleanup()
|
||||
|
||||
if __name__ == "__main__":
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
### Testing Without Hardware
|
||||
|
||||
Use virtual display mode for development:
|
||||
|
||||
```python
|
||||
hal = EReaderDisplayHAL(
|
||||
width=800,
|
||||
height=1200,
|
||||
virtual_display=True, # Uses Tkinter window
|
||||
enable_orientation=False, # No accelerometer
|
||||
enable_rtc=False, # No RTC
|
||||
enable_power_monitor=False, # No INA219
|
||||
)
|
||||
```
|
||||
|
||||

```
|
||||
|
||||
## Gesture Detection
|
||||
|
||||
The HAL implements comprehensive gesture detection:
|
||||
|
||||
| Gesture | Detection Criteria | Usage |
|
||||
|---------|-------------------|-------|
|
||||
| **TAP** | < 30px movement, < 300ms | Select links, buttons |
|
||||
| **LONG_PRESS** | < 30px movement, >= 500ms | Context menu, definitions |
|
||||
| **SWIPE_LEFT** | Horizontal, dx < -30px | Next page |
|
||||
| **SWIPE_RIGHT** | Horizontal, dx > 30px | Previous page |
|
||||
| **SWIPE_UP** | Vertical, dy < -30px | Open navigation |
|
||||
| **SWIPE_DOWN** | Vertical, dy > 30px | Open settings |
|
||||
| **PINCH_IN** | Two-finger distance decrease | Decrease font size |
|
||||
| **PINCH_OUT** | Two-finger distance increase | Increase font size |
|
||||
|
||||
## E-ink Optimization
|
||||
|
||||
The display driver implements several e-ink optimizations:
|
||||
|
||||
### Refresh Modes
|
||||
|
||||
- **FAST** (DU mode): ~200ms, for text/UI updates
|
||||
- **QUALITY** (GC16 mode): ~1000ms, for images
|
||||
- **FULL** (INIT mode): Full refresh to clear ghosting
|
||||
- **AUTO**: Automatically chooses based on content
|
||||
|
||||
### Power Saving
|
||||
|
||||
**Automatic Display Sleep**: The display automatically enters sleep mode after each update to save power. E-ink displays only need power during refresh, not for static content. This significantly extends battery life.
|
||||
|
||||
To disable auto-sleep (e.g., for rapid successive updates):
|
||||
|
||||
```python
|
||||
hal = EReaderDisplayHAL(
|
||||
width=800,
|
||||
height=1200,
|
||||
auto_sleep_display=False # Keep display awake
|
||||

|
||||
```
|
||||
|
||||
## Real-Time Clock (RTC)
|
||||
|
||||
The HAL includes a PCF8523 RTC for accurate timekeeping with battery backup:
|
||||
|
||||
### Features
|
||||
|
||||
- **Battery-backed timekeeping** - Maintains time when device is off
|
||||
- **Alarm support** - Minute-precision alarms for wake events
|
||||
- **Auto-sync** - Syncs with system time after power loss
|
||||
- **Calibration** - Clock accuracy adjustment support
|
||||
|
||||
### Usage
|
||||
|
||||
```python
|
||||
import time
|
||||
|
||||
# Get current time
|
||||
current_time = await hal.get_datetime()
|
||||
print(time.strftime("%Y-%m-%d %H:%M:%S", current_time))
|
||||
|
||||
# Set time
|
||||
new_time = time.localtime() # Use current system time
|
||||
await hal.set_datetime(new_time)
|
||||
|
||||
# Set alarm for 7:30 AM
|
||||
await hal.set_alarm(hour=7, minute=30)
|
||||
```
|
||||
|
||||
See [examples/rtc_demo.py](examples/rtc_demo.py) for a complete example.
|
||||
|
||||
## Touchscreen Calibration
|
||||
|
||||
The HAL includes touchscreen calibration to align touch coordinates with display pixels:
|
||||
|
||||
```bash
|
||||
# Run calibration (displays touch targets)
|
||||
cd examples
|
||||
python3 calibrate_touch.py
|
||||
|
||||
# Test calibration
|
||||
python3 test_calibration.py
|
||||
```
|
||||
|
||||
Calibration uses affine transformation with least-squares fitting to achieve sub-5-pixel accuracy. See **[CALIBRATION.md](CALIBRATION.md)** for detailed documentation.
|
||||
|
||||
## Examples
|
||||
|
||||
See the `examples/` directory for complete examples:
|
||||
|
||||
- **[simple_display.py](examples/simple_display.py)** - Basic display and touch demo
|
||||
- **[battery_monitor.py](examples/battery_monitor.py)** - Power monitoring demo
|
||||
- **[rtc_demo.py](examples/rtc_demo.py)** - RTC timekeeping and alarms demo

||||
Run examples:
|
||||
|
||||
```bash
|
||||
cd examples
|
||||
python3 simple_display.py
|
||||
```
|
||||
|
||||
## Hardware Setup
|
||||
|
||||
### Connections
|
||||
|
||||
All components connect via I2C and SPI:
|
||||
|
||||
| Component | Interface | Default Address | Pins |
|
||||
|-----------|-----------|-----------------|------|
|
||||
| IT8951 | SPI | N/A | MOSI, MISO, SCK, CS, HRDY, RESET |
|
||||
| FT5316 | I2C | 0x38 | SDA, SCL |
|
||||
| BMA400 | I2C | 0x14 | SDA, SCL |
|
||||
| PCF8523 | I2C | 0x68 | SDA, SCL |
|
||||
| INA219 | I2C | 0x40 | SDA, SCL |
|
||||
|
||||
### Enable I2C and SPI
|
||||
|
||||
On Raspberry Pi:
|
||||
|
||||
```bash
|
||||
sudo raspi-config
|
||||
# Navigate to: Interface Options > I2C > Enable
|
||||
# Navigate to: Interface Options > SPI > Enable
|
||||
```
|
||||
|
||||
### Verify Devices
|
||||
|
||||
```bash
|
||||
# Check I2C devices
|
||||
i2cdetect -y 1
|
||||
|
||||
# Expected output shows addresses: 0x14, 0x38, 0x40, 0x68
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
The project uses pytest for testing:
|
||||
|
||||
```bash
|
||||
# Install dev dependencies
|
||||
pip install -e .[dev]
|
||||
|
||||
# Run tests
|
||||
pytest tests/
|
||||
|
||||
# Run with coverage
|
||||
pytest --cov=dreader_hal tests/
|
||||
```
|
||||
|
||||
Note: Hardware-specific tests require actual devices connected. Mock tests run without hardware.
|
||||
|
||||

|
||||
### Adding Tests
|
||||
|
||||
Since PyBMA400, PyFTtxx6, and PyPCF8523 are our repos, we can add tests directly to them as needed.
|
||||
|
||||
For HAL-level tests, use the `tests/` directory:
|
||||
|
||||
```python
|
||||
# tests/unit/test_hal.py
|
||||
import pytest
|
||||
from dreader_hal import EReaderDisplayHAL
|
||||
|
||||
@pytest.mark.asyncio
|
||||
async def test_hal_initialization():
|
||||
hal = EReaderDisplayHAL(virtual_display=True)
|
||||
await hal.initialize()
|
||||
assert hal._initialized
|
||||
await hal.cleanup()
|
||||
```
|
||||
|
||||
## Performance
|
||||
|
||||
Target performance metrics (from HAL spec):
|
||||
|
||||
| Metric | Target | Critical |
|
||||
|--------|--------|----------|
|
||||
| Image display latency | < 100ms | < 500ms |
|
||||
| Touch event latency | < 50ms | < 200ms |
|
||||
| E-ink refresh (fast) | < 200ms | < 500ms |
|
||||
| E-ink refresh (full) | < 1000ms | < 2000ms |
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Display not working
|
||||
|
||||
- Check SPI is enabled: `ls /dev/spi*`
|
||||
- Verify connections (MOSI, MISO, SCK, CS, HRDY, RESET)
|
||||
- Check VCOM voltage matches your device
|
||||
|
||||
### Touch not detecting
|
||||
|
||||
- Check I2C device: `i2cdetect -y 1` (should see 0x38)
|
||||
- Verify SDA/SCL connections
|
||||
- Check polling interval (default 10ms)
|
||||
|
||||
### Power monitor errors
|
||||
|
||||
- Verify shunt resistor value (default 0.1Ω)
|
||||
- Check I2C address (default 0x40)
|
||||
- Ensure max_expected_amps is appropriate
|
||||
