Our school organized a RoboMaster team and planned to attend the competition this year. Since we are all new students at a new campus, we do not have any reference materials available from previous students, and we have to figure out bugs after bugs on our own. This post describes some of the problems we met during software development. Hardware: RoboMaster Official Development Board MCU Model: STM32F427IIHx Software: ChibiOS 18.2.0 Board Has 12 MHz HSE Clock Instead of Commonly Seen 8MHz The pitfall is that neither the manual nor the hardware schematics mentioned the clock frequency. Due to this problem, the actual frequency we programmatically set with STM32CubeMX or other software is much higher than expected. This caused the following problems:...
