Arduino for STM32

You did not enter the correct timer channel values in the PIN_MAP table, position 5 of the rows.
The current value 0 can lead to hang up.

Btw, you do not need to set the mode for PWM pins, it is set in the core when calling analogWrite() (see here).

Or, as a faster alternative, you could set only once the pin mode to PWM in setup and then use instead of

What should the timer channels be?

PB4: TIM3 CH1 (like PA6)
PB5: TIM3 CH2 (like PA7)
PA15: TIM2 CH1 (like PA0)

1 for CH1, 2 for CH2.

ohh stupid me

Ok mostly working but PA1 and PA11 have stopped doing pwm... but not hanging

That is normal, since you have remapped the timer pin which was previously mapped to PA0.
If you check table 45 in RM0008 page 178 you will see that by remapping timer 2 channel 1 from PA0 to PA15, the timer 2 channel 2 was also automatically remapped from PA1 to PB3.
This is a HW restriction which you have to live with.

However, PA11 (TIM1_CH4) should remain unaffected from these remappings.

well for some reason PA11, there is a PWM going on but its in the mV... The full high and low is still working on that pin so i dont think its a dead pin...
Ive also just tested on another board and getting the same thing on PA11...

As For PA1, what are my options? I need PWM control on that pin as well :/
Actually I just isolated PA11 pwm control, and there isnt a mV reading on it any more... I think that might have been noise :/

PA11 not working at all in PWM now. Even with the original pin map :/

Ok I guess i can just hotwire PB1 to PA1 and use that pin as that still works... Gah two hotwires....... not happy but at least that would work.

Also PA11 is still not behaving :/ Last thing i need to sort out

Be aware that PA11 is per default a USB pin.

I took out USB serial in the stlink upload option in the boards.txt file. Is there anything else i need to do?
