Is the 32-bit ATSAML10 the ATMEGA328P killer that we've been waiting for?

AFAIK, MySensors currently only works with the unofficial one from Roger Clark

I'm using Blue Pills with stm32duino (https://github.com/stm32duino/Arduino_Core_STM32) and MySensors without problems.
Stm32duino also supports a number of STM32L variants.

@yveaux I stand corrected. I just tried compiling an example sketch and indeed no errors. Last time I tried I had compilation errors, but that may have been due to other factors then.

@freynder Yes. I had a Blue Pill with RFM69 working from stm32duino, but it has been a while.

It seems that blue pills are now cheaper than pro mini's: https://www.aliexpress.com/item/STM32F103C8T6-ARM-STM32-Minimum-System-Development-Board-Module-For-arduino-DIY-KIT-Sensing-Evaluation-for-Skiller/32839140960.html?spm=2114.search0604.3.21.5f1f5d6f9DVrT6&ws_ab_test=searchweb0_0,searchweb201602_2_10152_10065_10151_10344_10068_10130_5724113_10342_10547_10343_5724713_10546_10340_10341_10548_315_10545_10696_5724013_10084_531_10083_10618_5724313_10307_5724213_10059_100031_10103_5725013_10624_10623_10622_10621_10620_5724913,searchweb201603_55,ppcSwitch_7&algo_expid=39b863cc-b9e0-40b1-b7ad-1e800e717f83-6&algo_pvid=39b863cc-b9e0-40b1-b7ad-1e800e717f83&priceBeautifyAB=0

You can even put a USB bootloader onto them.

@neverdie so will it be able to run mysensors also in sleep mode? I got lost with all those chip codes

plus debug using Black Magic Probe or stlink + OpenOCD

I'm revisiting this as I tried to compile a sketch today using the official STM32 core (https://github.com/stm32duino/Arduino_Core_STM32 v1.3)

I realize now I tested with the wrong core as it is a bit confusing in Arduino IDE. Please see the screenshot below which boards menu should be selected (highlighted the selected board).

When I select this core, the sketch will not compile because the ARDUINO_ARCH_STM32F1 flag is not set.

@Yveaux and @nagelc : can you confirm you actually used this core? The core named "STM32 Boards (stm32duino.com)" is Roger Clarks core, not the official STM32 core one. Easily confused as the github user name for the official STM32 core is stm32duino.

[nagelc]

@freynder I have changed computers since then, but I suspect you are right. I found it through the STM32duino site, but it didn't look like your screen shot. I don't recall seeing "series" after STM32F103. I can double check when I get home next week.

[Yveaux]

@freynder This is the one I used on the pills:

And the boards I've got installed:

@yveaux and @scalz

Thanks for confirming. So only Clark's core is supported at the moment.

It would be interesting to support the official STM32 core as they provide low power functions. I will do some experiments.

[NeverDie]

Do any of the STM32's have anything similar to the Nordic nRF52's PPI (Programmable Peripheral Interconnect)? I assumed they would, but I just now went looking for it in the datasheet and didn't find it. Maybe STM32's call it something else? Or do they just not have anything similar? I thought it was a rather cool feature of the nRF52.
