IC解密STM32CUBEMX+DHT11+LCD1602温湿度
IC解密单片机源程序如下:
- /* USER CODE BEGIN PV */
- IC解密uint8_t DHT11Flag = 1; // DHT11Flag==0表示DHT11存在
- IC解密uint8_t TempData;//温度数据
- IC解密uint8_t HumiData;//湿度数据
- // 定义全局字符串变量
- const char g_send_str[] = "Demo Data Acquisition!\r\n";
- const char g_exist_str[] = "DHT11 exist!\r\n";
- const char g_no_exist_str[] = "DHT11 not exist!\r\n";
- char TempStr[16]; // 用于存储温度的字符串形式
- char HumiStr[16]; // 用于存储湿度的字符串形式
- uint8_t uart_buf[64]; // 扩大缓冲区预留余量
- uint16_t buf_len;
- /* USER CODE END PV */

- void SystemClock_Config(void);

- HAL_Delay(500);
- LCD_Clear();

- {

- DHT11Flag = DHT11_Check();
- if(DHT11Flag ==0)
