Simple driver implemented in C for SHT21 using ST's STM32F401RE Nucleo board.
SHT21 is a temperature and humidity sensor. The I2C bus is used to communicate with it.
The pin configuration is as follows:
- VCC - Supply
- GND - Ground
- SCL - I2C Clock
- SDA - I2C Data
Folders:
- /Driver_code folder for the driver implementation source code and more details.
- /SHT21_example folder there is an example that can be ported directly to STM32IDE.
- /Doc has the main manuals used for the SHT21 and images for the Readme.
For now the current operations are supported:
- Read/Write operations on the I2C bus (generalised)
- Reading values from the temperature/humidity sensor
- Verify correct data reception (CRC check)
