資源簡介

STM32之間的串口通信，代碼調(diào)試完全可用，使用的是基于正點(diǎn)原子的開發(fā)板，一個(gè)是mini板，一個(gè)是精英板，通過迷你板的USART3（PB10，PB11）串口實(shí)現(xiàn)輸出，通過精英板的USART3（PB10，PB11）串口實(shí)現(xiàn)讀取，并且通過USART1（就是CH340下載程序的那個(gè)串口）打印輸出（使用串口調(diào)試助手可用看到），并且可用實(shí)現(xiàn)LCD的屏幕顯示串口接收到的內(nèi)容。 注意： 1、如果沒有迷你板，可用使用串口助手輸出的功能代替，（另外一臺電腦的助手輸出，本機(jī)電腦助手需要檢測精英板的串口輸出情況） 2、如果沒有LCD屏幕，可用注釋掉主函數(shù)相應(yīng)的LCD初始化以及代碼即可 3、接收端的精英板如果串口3接收成功，LED10翻轉(zhuǎn)，如果串口1發(fā)送成功，LED1翻轉(zhuǎn)。
