基于stm32写一个串口接收函数并存在缓冲数组中

以下是基于STM32写的一个串口接收函数，并将接收到的数据存储在缓冲数组中：

#include "stm32f10x.h"

#define BUFFER_SIZE 256

char buffer[BUFFER_SIZE];
int bufferIndex = 0;

void USART1_IRQHandler(void) {
    if (USART_GetITStatus(USART1, USART_IT_RXNE) != RESET) {
        char data = USART_ReceiveData(USART1);
        buffer[bufferIndex++] = data;
        if (bufferIndex >= BUFFER_SIZE) {
            bufferIndex = 0;
        }
    }
}

void setup() {
    // 初始化串口1
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_USART1, ENABLE);

    GPIO_InitTypeDef gpioStructure;
    gpioStructure.GPIO_Pin = GPIO_Pin_9 | GPIO_Pin_10;
    gpioStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    gpioStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &gpioStructure);

    USART_InitTypeDef usartStructure;
    usartStructure.USART_BaudRate = 115200;
    usartStructure.USART_WordLength = USART_WordLength_8b;
    usartStructure.USART_StopBits = USART_StopBits_1;
    usartStructure.USART_Parity = USART_Parity_No;
    usartStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
    usartStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
    USART_Init(USART1, &usartStructure);

    NVIC_SetPriority(USART1_IRQn, 0);
    NVIC_EnableIRQ(USART1_IRQn);

    USART_Cmd(USART1, ENABLE);
}

int main(void) {
    setup();
    while (1) {
        // Do something
    }
    return 0;
}

此函数将通过USART1接收数据，并将其存储在缓冲区中。在此示例中，缓冲区的大小为256字节，但可以根据需要进行更改。
