Modules

Modules for this board:

Methods:

steering_can_init()
steering_can_process_event()

button_press_init() // sets up interrupts for buttons and generates events

Operation

processes events and sends steering CAN messages.

signal_stalk_init() // sets up analog_readers

Operation

Uses an analog reader to read voltages, and converts them to signal events

Operation

Uses an analog reader to read voltages, and converts them to cruise control events.

accepts a callback, repeatedly calls that callback with new data as it gets new data.
