Arduino for STM32

Did best answer get removed or is it not enabled for this particular board? Well, Originally you create a topic here which should only contains SubForum: Board index < Arduino for STM32 < Cores < STM32 Core I move it here: Board index < Arduino for STM32 < Cores < STM32 Core < General discussion Th...

Like Ralf9 said
For 1.8 you need to do the setMode.
This will not be needed for next release.
Anyway, as you get the example on the master it is not present.

Hi Ben
Check in the wiki the HardwareTimer page and the STM32Examples, you will find what you search from.

There is a lot of pins linked to a Timer. The analogWrite well use the timer if available on the requested pins. One other solution is to use directly the HardwareTimer api: https://github.com/stm32duino/wiki/wiki/HardwareTimer-library This is what is called by the analogWrite when Timer is availabl...

Thanks MGeo,

About DWT, note that the core is already based on it for delayMicroseconds() arduino API

Hi comiter I don't think the IWDG can do this. You can specify to stop in debug mode but that's all. When the IWDG fire then it enter in reset. The WWDG should be able to save the PC in a backup register thanks the WWDG_IRQn handler but you have to implement it yourself as there is no Arduino librar...

Looking at the code, it is for the STM32 core.

If it works individually, I guess you can have those kind of issues:
- IRQ priority
- TIMER shared ressource

The best would be you can debug to see exactly why you failed?

Well, I've reproduced the issue but I didn't have the solution.
Seems it is current to have issue with ADC3 on those series.
I raise an issue internal.
As a workaround simply use other ADC1 or 2.

Any update on this ?

Hmm ... it’s not clear ... I just replaced PC13 with PA3 (for the test). There is PWM on PA3, but not on PC13. It seems that the PWM core is not configured for all pins. So if there is no PWM linked to PC13, the analogWrite simply use it as a digitla IO. If the requested value is less than the half...
