STM32F207串口12DMA源码,3,4普通串口
STM32F207串口例子串口1,2为DMA发送与接收串口3,4没有使用DMA。
工程为KEILC。
4个串口发送接收都在硬件板是测试过的。
需要留意的是我的硬件板的晶振是25M,如果你的晶振不一样,需要在system_stm32f2xx.c文件中修改#ifndefRMII_MODE/*Systemclockfrequencyconfiguredfor120MHz****************************//*PLL_VCO=(HSE_VALUEorHSI_VALUE/PLL_M)*PLL_N*/#definePLL_M25
