Hi all!
I'm working with STM8S003F3 chip on my project and I'm have some problem about it,
i wana help of ST technician. on my project,i using pin4 and pin5 of port B to control normal IO applications,I have already used sample code of ST's library about GPIO in stm8s_gpio.c file, i have already written code following:
int main(void){
but it not run. the voltage of this pin ~1.85V when it high and = 0.00V when it low
I have already used this code to control all of other pin of other port,it run fine. I have already used this code too to control pin4 and pin5 of portB of STM8S105C6T6 chip on stm8s-discovery board,it run fine.
May be it have some special thing about these pins??
Please help me answer it.

thanks and best regard!
