LED1/2/3 working on arduino but not on CUBEMX
Hello, i just bought a STM32WL55JC2. It's working perfectly on Arduino but i want to use the LORA module and Arduino doesn't support it.
I've configured my stm on CubeMX and tried a basic HAL_GPIO_WritePin but it doesn't work and i can't figure why.

Arduino working code :
Thank you :)
