对于stm32f103c8t6与陶晶驰串口屏通信,您可以参考以下代码示例:
```c
#include "stm32f10x.h"
void USART_Configuration(void) {
// 初始化GPIO
GPIO_InitTypeDef GPIO_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStructure);
// 初始化USART
USART_InitTypeDef USART_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1, ENABLE);
USART_InitStructure.USART_BaudRate = 9600;
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;
USART_Init(USART1, &USART_InitStructure);
// 使能USART
USART_Cmd(USART1, ENABLE);
}
void USART_SendString(char* str) {
while (*str) {
while (USART_GetFlagStatus(USART1, USART_FLAG_TXE) == RESET);
USART_SendData(USART1, *str++);
}
}
int main(void) {
// 初始化串口
USART_Configuration();
// 发送数据到串口屏幕
char* message = "Hello, TFT!";
USART_SendString(message);
while (1) {
// 主循环
}
}
```
在这个例子中,我们首先需要初始化GPIO和USART,然后在`USART_SendString`函数中发送字符串到串口屏幕。在主函数中,我们调用`USART_SendString`函数发送消息。
