Logic to control the DRV8824/25 motor driver board. The original application is to control a dual axis CNC frame using two steppers per axis. However, the code could be adapted for use in any stepper application.
The main src files are:
stepper.cStepper driver. Includes functions to step an arbitrary amount of steps or milimeters (given a set gear circumference).queue.cSimple queue structure that can be used to make sequentially steps. Note that both the x and y axis can step in parallel.stepper_control.cFunctions to control stepper motors for chess robot. Makes use of queue to add moves and converts square Universal Chess Interface coordinates to millimeters/steps.gpio.cGeneral GPIO control functions STM32 microcontrollers.
Run make test_queue. This will download the Unity testing framework and run the
the unit tests in test_queue.c.
