Go back to your simple project with just the I2C - nothing else If that works, then add just one UART, doing a simple, polled echo - no interrupts If that works, then add the other UART, also doing a simple, polled echo - no interrupts If that works, then convert just one...

使用USART接收中断(根据接收数据的个数判断接收是否完成)连续接收数据时注意使用HAL_UART_Receive_IT(&huart1,buff,buffsize);重复使能中断。需要在中断回调函数的最后再使用HAL_UART_Receive_IT(&huart1,buff,buffsize);使能一次。//The specific UART interrupts (Transmission complete interrupt, RXNE interrupt /...

曾经玩Linux时非常喜欢这种基于出串口的控制台, 通过简单的串口TX和RX能实现嵌入式硬件的人机交互,非常实用, 那么STM32能否实现通过超级终端与用户互动的构想呢? 答案是肯定的,由于这个UART控制平台就像应用程序套上一层可访问的外科(Shell)故而我将这种基于UART的控制平台简称Shell,构架和效果如下图: ...
