此处的思路是完全采用HAL库来实现的,核心是运用HAL_UART_Transmit_IT和HAL_UART_Receive_IT两个函数来实现的,可以作为一个Demo来测试使用; 直接上代码,其串口的配置和上一章完全一致,因此忽略不计: 思路大致是将aTxStartMessage字符串发送出去,接收一个总长度为15个字符的数据到aRxBuffer中,等待接收完毕; ...
If the UART supports RTO, that is almost always what you want, rather than "receive to idle". See the examples by Tilen Majerle here. Or, use continuous receive with circular buffer example The HAL driver unfortunately is too complicated to work reliably. 0 Kudos Rep...

I have read this issueSTMicroelectronics/stm32f1xx-hal-driver#4and read the example code, but it does not solve my issue. The issue also states: Use of HAL_UARTEx_ReceiveToIdle_DMA service, will generate calls to user defined HAL_UARTEx_RxEventCallback callback for each occurrence of ...
