Note for receiving, if you use interrupt mode, the interrupt will only be triggered when the buffer RX_BUF is full, assuming you are using the HAL_UART_RxCpltCallback function.*/// 以下默认配置参数就比较好用,非必要可以不用修改//!!! 发送模式: 0 - 阻断模式(不推荐);1 - 中断模式(还可...

The monitor can be opened inside the AURIX™ Development Studio using the following icon: › The serial monitor must be configured with the following parameters to enable the communication between the board and the PC: – Speed (baud): 115200 – Data bits: 8 – Stop bit: 1 Copyright ...

I do UART periodically transmitting using DMA. Without interrupt it works perfectly. I tried to add interrupt functionality and have a problem. the dma interrupt has been called (void dmacb()), but after that faultISR is called...
The UART trace backends allow the pins and UART1 interrupt priority to be set using the devicetree. Other configurations set in the devicetree, such as the current speed, are overwritten by the UART trace backends. .. note:: When one of the UART trace backends is enabled by either the ...
