Arduino for STM32

The full code please.

did you try unitary on those pins ?


My code has more thank 3k lines! I think you want my pinout setup:

pinMode(OK_B, INPUT_PULLUP);
pinMode(UP_B, INPUT_PULLUP);
pinMode(DOWN_B, INPUT_PULLUP);
pinMode(CANCEL_B, INPUT_PULLUP);
pinMode(START_B, INPUT_PULLUP);
pinMode ...

Sorry I didn't get notify by email and notificactions.

I send my code of attaching and detacching interrupt

// Función de pulsadores des/habilitadas
void pulsa_st_on()
{
attachInterrupt(START_B,ST_EXTI_ISR,FALLING);
}
void pulsa_st_off()
{
detachInterrupt(START_B);
}

I try to add:

__DSB ...

Hi,
I'm working with STM32 BluePill in a like PLC board, and I use 6 GPIOs as user Inputs.
4 are tact switches for menu navigation conected to PA6, PA7, PB10, PB11
2 are for Start and Stop commands in PA4 and PA5.
I use TMR2 INT every 1 ms to make various functions and one of them are debounce for ...

Hi I'm Stephan and I'm working in a personal project, it's like a PLC but I use BluePill as processor and I'm programming with PlatformIO and Arduino Framework. I hope I can bring my help to this community, best
