- Install Library from https://github.com/nimaltd/STM32-PACK/raw/main/EE24/NimaLTD.I-CUBE-EE24.pdsc
- Add and enable it.
- Enable I2C.
- Select 'Generate peripheral initialization as a pair of .c/.h files per peripheral' on the Code Generator Tab.
- Generate code.
- Define a structure of
EE24_HandleTypeDef. - Call
EE24_Init()and enjoy.
