帮我写个esp32与stm32串口通信代码,esp32基于ESP-IDF,stm32基于keil
好的,我可以回答这个问题。以下是一个简单的示例代码:
ESP32 代码:
```c
#include "driver/uart.h"
void app_main()
{
uart_config_t uart_config = {
.baud_rate = 115200,
.data_bits = UART_DATA_8_BITS,
.parity = UART_PARITY_DISABLE,
.stop_bits = UART_STOP_BITS_1,
.flow_ctrl = UART_HW_FLOWCTRL_DISABLE
};
uart_param_config(UART_NUM_1, &uart_config);
uart_set_pin(UART_NUM_1, 17, 16, UART_PIN_NO_CHANGE, UART_PIN_NO_CHANGE);
uart_driver_install(UART_NUM_1, 1024, , , NULL, );
while (1) {
uart_write_bytes(UART_NUM_1, "Hello STM32!\n", 14);
vTaskDelay(100 / portTICK_RATE_MS);
}
}
```
STM32 代码:
```c
#include "stm32f10x.h"
#include "stdio.h"
void USART1_Init(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
USART_InitTypeDef USART_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_USART1, 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);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(GPIOA, &GPIO_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_Rx | USART_Mode_Tx;
USART_Init(USART1, &USART_InitStructure);
USART_Cmd(USART1, ENABLE);
}
int main(void)
{
USART1_Init();
while (1) {
if (USART_GetFlagStatus(USART1, USART_FLAG_RXNE) == SET) {
char ch = USART_ReceiveData(USART1);
printf("Received: %c\n", ch);
}
}
}
```
这两个代码可以实现 ESP32 和 STM32 之间的串口通信。你可以根据自己的需求进行修改。

好的,我可以回答这个问题。以下是一个简单的 ESP32 和 STM32 串口通信代码示例:
ESP32 代码:
```
#include <HardwareSerial.h>
HardwareSerial Serial2(2);
void setup() {
Serial.begin(115200);
Serial2.begin(115200, SERIAL_8N1, 16, 17);
}
void loop() {
if (Serial2.available()) {
Serial.write(Serial2.read());
}
if (Serial.available()) {
Serial2.write(Serial.read());
}
}
```
STM32 代码:
```
#include <SoftwareSerial.h>
SoftwareSerial Serial2(PA3, PA2);
void setup() {
Serial.begin(115200);
Serial2.begin(115200);
}
void loop() {
if (Serial2.available()) {
Serial.write(Serial2.read());
}
if (Serial.available()) {
Serial2.write(Serial.read());
}
}
```
这个代码示例使用了 ESP32 的硬件串口和 STM32 的软件串口,可以实现两个板子之间的串口通信。
