STM32+ESP8266点灯（STA 模式）点灯（2）

1、简介

STM32+ESP8266点灯（AP+STA 模式）点灯（1）一文已经通过串口助手实现与网络调试助手透传，本文通过STM32单片机替代网络调试助手，实现远程点灯。

2、单片机配置

2.1 cubemax配置

2.1.1 RCC配置

 2.1.2 SYS配置

  2.1.3 时钟树配置

   2.1.4 LED配置

  2.1.5 UART配置

 2.1.6 UART配置

 2.2 KEIL 5配置

2.2.1 led宏定义

#define LED_ON  HAL_GPIO_WritePin(LED_GPIO_Port,LED_Pin,GPIO_PIN_SET)
#define LED_OFF HAL_GPIO_WritePin(LED_GPIO_Port,LED_Pin,GPIO_PIN_RESET)

 2.2.2 串口配置

#include "stdio.h"

/* USER CODE BEGIN 1 */
int fputc(int ch, FILE *f)
{
 uint8_t temp[1] = {ch};
 HAL_UART_Transmit(&huart1, temp, 1, 2);
 //HAL_UART_Transmit(&huart2, temp, 1, 2);
 return ch;
}
/* USER CODE END 1 */

 2.2.3 联网配置

3、测试

在网络调试助手分别发送A、B进行点灯关灯。
