End of line tester firmware

The end of line tester firmware is an application for the ARDEP Power IO Shield that can be used in manufacturing to test the functionality of the Power IO Shield.

Setup

Connect all inputs to the corresponding outputs on the Power IO Shield. (I.e. connect input 0 to output 0, input 1 to output 1, etc.).

Do not forget to connect 12V power to the shield/ARDEP and set the power mux to the correct position to power the Power IO Shield.

Usage

To use it, connect an Power IO Shield to an ARDEP board, flash this firmware, and run the host.py script from the samples/power_io_shield/end_of_line_tester/ directory on a host computer connected to the ARDEP board via UART. Specify the correct serial port via the --port argument.

The script will tell the firmware to start the test by sending START via UART and will then test all digital inputs and outputs of the Power IO Shield.

If the test passes a message End of line tester completed successfully is printed, otherwise an error message is shown.
