Re: analogRead and analogWrite troubles
2. I receive freezing of the chip trying to do analogRead from PA3. The rest of analog reads from other pins work perfectly. Seems strange if other works. 3. I still receive the same behaviour of analogWrite for PA4 & PA5 in the strict behaviour of analogRead code (https://github.com/stm32duino...

Re: analogRead and analogWrite troubles
Hi, For analogWrite on PA4 and PA5, this is the normal behaviour as there is no timer linked to those pins: https://github.com/stm32duino/Arduino_Tools/blob/31f3d43d620878dccbf658f65095f66fec9809b2/src/genpinmap/Arduino/STM32F103R(8-B)Tx/PeripheralPins.c#L88-L136 So it operates like a digital pin: 0...

Re: [Q] How to know how much RAM memory microcontroller have at compile time?
Hi,
You should have a look at this example:
https://github.com/stm32duino/STM32Exam ... istics.ino
Using the linker script definitions _estack and _sdata should do the trick
But during execution not build time.

Re: Limit on attachment image sizes?
This is the default configuration and currently, I would keep it as it is. IIWR, Roger set a smaller size (64k) so this is already higher than before. The forumconfiguration will evolve, it's just reopen so I guess some tuning will be required. At this time, let's see how this qoes. I'm agree with m...
