a basic program to read from the sensors over i2c. I looked at the source code for RTIMULibDrive11 and the datasheets for HTS221 and LPS25H to build the program. Here is the source code for anyone interested (very simple but it gets the job done).

温湿度传感器HTS221驱动，stm32环境，亲测可用(Temperature and humidity sensor HTS221 drive, STM32 environment, pro test available)

参考网上其他例程自行编写的HTS221温度湿度传感器驱动代码，是应用HAL库I2C进行通信。只编写了温度部分，可以输出实际温度值。
