void timer_hall_mode_config(uint32_t timer_periph, uint32_t hallmode);官方库里的这个霍尔模式函数到底整体是怎么用的，也没看到什么例程，我现在不是用这个模式驱动的bldc，别的都没问题，但是我想要记录无刷电机的移动的行程，记录不准，所以我想这用这个模式是不是就能准，有大佬知道原因吗

1. APM32F417IGT6和STM32F417IGT6的区别就是APM32F417IGT6多了一个DMC么?2. 是否能在stm32cubemx中当作STM32F427IGT6用?

想用逻辑分析仪捕捉GPIO信息，但是一直显示unkown signal，不知道是哪里的问题
