LED1/2/3 working on arduino but not on CUBEMX

[BNamu.1]

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 🙂

yea, but i see: _MODER shows 0xFFFF... -> pins are on analog mode !!!!! so no hi/lo output.

where you set it analog? check!

[BNamu.1]

i generated the code automatically so i didn't change anything. I don't know how to change this.

check: did you

 

x set free pins as analog ?

to test : just write

GPIOB->MODER = 0x55555555 ;

while ....set pin .... .

Nop this parameter isn't enable. BUT with GPIOB->MODER = 0x55555555 ; my led is now working !!! Thank youu, i still don't know why my pins are on analog mode but it's fine

ok, not fine , but we got it going.

there is some instruction doing this - or is an error in Cube/HAL , then you should set pins yourself and not trust in HAL . (it has some errors, shure.)
