Test scripts are provided in scripts/ folder. It uses BusPirate with a I2C clock stretching patch.1 The
implementation is based on the bus pirate lite reference python library (stripped down).
- scripts/ledtest.py: Fades LEDs in and out across a variety of colors.
- scripts/ledtest.py: Polls keypad peripheral and reports to console.
- scripts/ledtest.py: Generates pointless I2C traffic (used during test & validation).
Modifications may be needed since it always uses /dev/ttyUSB0. There doesn't seem to be a good way to auto detect BusPirate 3.x devices as they report as standard FTDI devices.
