Arduino for STM32

I can see several differences in the two versions, for example the usage of 2 external interrupts in the Arduino version that I can’t see in the STM version, so the two sketches don’t seem equivalent on a first check..

It seems to me you didn’t disable the systick which is a wakeup trigger.

Imangine the micros as composed of two parts that must be read separately: the integer part and the decimal part. Scenario: At time 10.992 you read the decimal part (0.992) At time 11.002 you read the integer part (11) Then you would return 11.992, which is far different from 10.992 or 11.002. Even ...

According to the specs, the blue pill does not have DAC, only ADC.
DAC is only supported on the bigger versions (the so said high density and xl density versions)

Do I need to change the oscillator as indicated in the post that you suggest me?

I had to changed the define BOARD_RCC_PLLMUL RCC_PLLMUL_6 for F_CPU==72000000, in boards_setup.cpp because the board has a 12khz oszillator.

If you have a 12MHz oscillator, yes.

Pay attention to this: Looks like you are using the option to upload via the legacy Maple bootloader.
Roger's one uploads to 0x08002000.

.... until the Official core incorporates PWM, the danieleff GENERIC core is a HAL wrapper and performs PWM: http://stm32duinoforum.com/forum/viewtopic.php?t=2194#p29860 Core: https://github.com/danieleff/STM32GENERIC Ray Just to clarify: the STM core already supports PWM but in the standard Arduino form...

Missing details I'd tend for sure to blame your code or synchronization design also because your sentence: I've also yet to flash the latest bootloader, was there such a bug in the original maple bootloader? seems to show lack of knowledge on how things work: there is no relationship between the boo...

Hello.
For who could be interested I pushed pull request #335 to support subject board with the official STM core.
Testing support would be welcome.

Thanks in advance and best, E.
