最常用的是通过串口输出uartlog,这种方法实现简单,大部分嵌入式芯片都有串口功能。但是这样简单的功能有时候却不是那么好用,比如: 一款新拿到的芯片,没有串口驱动时如何打印log 某些应用下对时序要求比较高,串口输出log占用时间太长怎么办?比如USB枚举。
当串口接收到数据时,便会自动产生中断并执行此函数 */ void USART1_IRQHandler(void) { unsigned char byte = 0; if (USART_GetITStatus(USART1, USART_IT_RXNE) != RESET) { byte = USART_ReceiveData(USART1); // Auto to clear RXNE flag when read! if (halUartOnIRQ != 0) halUartOnIRQ(...
