Arduino for STM32

Hi @ozcar, All your analysis is true, and adding refresh() before resume() is an appropriate solution. What is wrong, is the comment in the code you mentioned, it is no more fully appropriate since introduction of Pull Request https://github.com/stm32duino/Arduino_Core_STM32/pull/806 The appropriate...

Hi @el_fela , According to Blackpill Timer pin mapping PinMap_TIM[] , PB0 (or PB_0) is by default assigned to TIM1_CH2N : https://github.com/stm32duino/Arduino_Core_STM32/blob/0e00a8d8904d867acba88ddb313a804d4670b0b0/variants/STM32F4xx/F411C(C-E)(U-Y)/PeripheralPins_BLACKPILL_F411CE.c#L99 In order t...

Hi @mrubio, Unfortunately, no, you don't have a bluepill, this is a different board, even if they have both the same chip (stm32f103C8). Guys from UpBoard, reuse bluepill configuration (bluepill variant) by simplicity, to avoid to create their own, but this is clearly a mistake: On bluepill board th...

Hi @mrubio, I don't see issue in your code. So I tested on my bluepill (stm32f103c8), and everything work as expected: period 2000us and pulse high 1100us Below you can see the full sketch I used. Note: I am using "BluePill F103C8" variant ("Board part number" in Arduino IDE menu...

@aryan.ir For sure official core is able to work with 2 SPI instances in parallel.
And I am surprised that you cannot use SPI2 with "Adafruit_ILI9341.h"
Can you share the corresponding sketch?

Warning: SPI.setModule(2); Correspond to RogerClark's core whereas https://github.com/stm32duino/wiki/wiki/API#spi correspond to official STMicroelectronics core: Arduino_Core_STM32 and this setModule method doesn't exist in Arduino_Core_STM32 So which Core are you using ? Concerning Arduino_Core_ST...

I just figure out that there was an error in documentation (wiki).
probably a wrong copy/past. It is now fixed
The right information is:

With Arduino API setCaptureCompare() and setOverflow() I tried to abstract the complexity of Registers (where sometimes -1 is applies sometime not, depending on register), so for those API, when using TICK_FORMAT, the parameter is the number of tick (and not register value). * setOverflow() : if you...

setPWM() API is not designed to change duty only, it is there to fully configure the Timer from scratch.
To change only dutycycle, setCaptureCompare() is the appropriate API.

@Beuzekom , you need to check the revision of your chip, because there is a Hardware issue on some version. How to check revision: see datasheet https://www.st.com/resource/en/datasheet/stm32l082cz.pdf and look for "marking example" and "Revision code" For bug details, see errata...
