1、硬件IIC不需要自己去生成开始位结束位,只需调用配置函数LL_I2C_HandleTransfer,通过设置参数来进行收发 2、注意参数设定,例如 LL_I2C_MODE_AUTOEND 和 LL_I2C_GENERATE_START_WRITE 是用于写操作、LL_I2C_MODE_SOFTEND 和 LL_I2C_GENERATE_START_READ 是用于读操作 要注意分别。 3、加入超时设定,如果记时到...

Q: My Sketch doesn't start (Serial doesn't appear) A: Connect a USB-to-UART adapter to the default UART (eg. TX0/RX0 on Giga, TX/RX on Nano) and read the error message (with the sketch compiled in Default mode). If you don't own a USB-to-UART adapter, compile the sketch ...
