STM分支在RX中使用环形缓冲区了 [复制链接]

 stmhal/usbd_cdc_interface: Change CDC RX to use a circular buffer.

This should be a little more efficient (since we anyway scan the input
packet for the interrupt char), and it should also fix any non-atomic read
issues with the buffer state being changed during an interrupt.

为了提高效率，cdc RX改用环形缓冲区了。
