I2C configuration in STM32WL

Hello,

I'm trying to connect an OLED display to my STM32WL55JC by I2C but it doesn't work...

I've successfully connect it with a STM32F411RE but the I2C configuration / HAL interface seams to be different between both MCU...

Here my config on the STM32F4

Here my config on th STM32WL :

Does anyone know whats wrong ?

Thanks so much !

Hello @Community member ,

In the STM32Cube_FW_WL_V1.2.0 you can find code example of I2C under STM32Cube_FW_WL_V1.2.0\Projects\NUCLEO-WL55JC\Examples\I2C

You can compare your code with the example one to match the differences.

Tell me if you still faces issues.
