Arduino for STM32

Okay, thank you very much for your time and effort so far, this project is great!

Moreover the goal of the core is to support all STM32 series. I meant just split the entries in the .json file in a way to group similar boards together for the boards-manager only, not split the whole project/repo. Sorry if my wording was unclear. When you install the core you download 4 packages:...

Problem: When downloading the core from the boards manager I have to download all the supported boards from all the different families which makes the downloaded files large and slows down the download process. Possible solution: It would be great if you split them into multiple options (i.e. one f...

So this is a very basic question,
I was wondering whether it is possible to have 2 stm32 cores installed simultaneously on Arduino IDE? (e.g. Official core and Roger Clark's)
Would there be any conflicts or any overwritten data?

Thanks everyone!

Oh that's great! I didn't know that was a thing.
Okay then, how can I send/receive data?

Board: STM32F103C8T6 (Blue Pill) IDE: Arduino IDE Core: Official core I couldn't find any page mentioning USB communication neither in the GitHub wiki of the core nor here on the forums. So, is it possible to use USB communication to send and receive data alongside some existing code written on Ardu...

Hi @Leviro , could you share the code you used, please? I started with the example in the GitHub wiki, made the timer variable global, and used it to call setPWM in the loop: #define pin PA3 TIM_TypeDef *Instance = (TIM_TypeDef *)pinmap_peripheral(digitalPinToPinName(pin), PinMap_PWM); uint32_t cha...

If you can observe signal with oscilloscope that would be better. I don't have access to an oscilloscope right now thanks to COVID19. I will try using setCaptureCompare to change the duty cycle and see if it works. Also, when I set my AVOmeter to measure "DC Voltage" and input a PWM signa...

This problem appears in the official core. But Roger Clark's core works fine and doesn't have this issue. However, the I2C is unstable in Roger Clark's core so I have to use the official core.
