1.GPIO的正确设置GPIO_InitTypeDefGPIO_InitStructure;/*EnableGPIODclock*/RCC_APB2PeriphClockCmd(RCC_APB2Per
STM32F207的串口问题问：答1：RCC_APB2PeriphClockCmd(RCC_APB2Periph_USARTx,ENABLE)forUSART1andUSART6*RCC_APB1Pe
1.GPIO的正确设置GPIO_InitTypeDefGPIO_InitStructure;/*EnableGPIODclock*/RCC_APB2PeriphClockCmd(RCC_APB2Per
includestm32f10xhvoidGPIO_TimPWM(void){GPIO_InitTypeDefGPIO_InitStructure;RCC_APB2PeriphClockCmd(RCC
分别按下S1~S4，D1~D4分别点亮includestm32f10xhvoidDelay(unsignedintx);intmain(void){RCC_APB2PeriphClockCmd(RCC
