[Solved] How to use all available PWM for STM32

I wonder how to use all those PWM pins in my Arduino project. Should I use exactly those names? I.e.: `pinMode(PA_2_ALT0, OUTPUT);`

You should be using this Arduino “core”:
https://github.com/stm32duino/Arduino_Core_STM32

Much of the forum discussions around Roger’s core, GENERIC core, Blue_Pill, Maple_Mini will not be directly applicable to you.

However, your specific F4 board is not shown as up ported by default (yet) but new boards are added often. It is straight forward to build a variant for your board. See the WiKi:

Yes, I’ve already added that repository to Arduino IDE and I found my board among the available models.

However, your specific F4 board is not shown as up ported by default (yet) but new boards are added often.

I’m not sure to understand: here a screenshot of my IDE with this model selected.

My bad. Things change quickly in this forum…

No problem! Hence, I can use all that PWM pins with their names? I don’t want to use any other peripheral.

Consult your board schematic as STM often pre-configure hardware on some select pins. If the uC pin is “free”, you should be able to use as the pin map shows.

Ray

void setup()
{
analogWrite(PA_0, 180);
}

simply do a:
pinMode(PXy, OUTPUT);
analogWrite(PXy, <0 to 255>);

Warning: Use the pin number (PXy) not the pin name (PX_y).
analogWrite(PA0, 180);

//pinMode(PA0, OUTPUT);
analogWrite(PA0, 180);
