1、设定 UART1 时钟设定发送脚功能串口设置，使能#include “stm32f10x.h“void RCC_Configuration(void);void GPIO_Configuration(void);void USART_Configuration(void);unsigned char str=“A“;int main(void)RCC_Configuration();GPIO_Configuration();USART_Configuration();USART_SendData(USART1,str0); while(1);void RCC_Configuration(voi
2、d) RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1, ENABLE);void GPIO_Configuration(void)GPIO_InitTypeDef GPIO_InitStructure;/*只设定了发送*/GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;GPIO_Init(GPIOA, void USART_Con
3、figuration(void)USART_InitTypeDef USART_InitStructure;USART_InitStructure.USART_BaudRate = 115200;USART_InitStructure.USART_WordLength = USART_WordLength_8b;USART_InitStructure.USART_StopBits = USART_StopBits_1;USART_InitStructure.USART_Parity = USART_Parity_No;USART_InitStructure.USART_HardwareFlowControl= USART_HardwareFlowControl_None;USART_InitStructure.USART_Mode = USART_Mode_Tx; /*只设定了发送*/USART_Init(USART1 , USART_Cmd(USART1, ENABLE);
