单片机实现模拟I2C通信，代码完全可以直接使用，我已经测试通过。可以移植到任何单片机使用。-MCU for analog I2C communication, the code can be used directly, I have the test. Can be ported to any microcontroller to use.

STM32F103系列单片机用硬件IIC实现对外部器件的读写，非模拟IIC。-STM32F103 MCU hardware IIC external devices to achieve literacy, non-simulated IIC.

sht21驱动程序，使用模拟I2C通信，单片机选用STM32F103C8T6-sht21 drivers, analog I2C communication, MCU selection STM32F103C8T6
