温湿度sht2x基于stm32

在STM32平台上使用SHT2x温湿度传感器，同样需要进行硬件连接和软件驱动。

硬件连接方面，需要将传感器的供电电源和I2C总线连接到STM32的相应引脚上，并设置相关的I2C地址和通信频率等参数。下面是一份基于STM32F103平台的SHT2x硬件连接示意图：


软件驱动方面，可以使用STM32的HAL库来实现对SHT2x传感器的读取和计算。下面是一份基于STM32F103平台的SHT2x软件驱动示例代码：

}

static void MX_GPIO_Init(void)
{

  // Calculate temperature
  *temp = (175.0f * ((buff[0] << 8) | buff[1]) / 65535.0f) - 45.0f;

  // Calculate humidity

这个例程包括了初始化I2C、初始化传感器、读取温湿度值等功能。您需要根据自己的单片机平台和I2C库进行适当的修改。
