Arduino for STM32

Hello

Sorry for the delay in responding, I was sick and could not follow up on this.

I have tested the stm32duino example (https://github.com/stm32duino/STM32Examples/blob/main/examples/Peripherals/HardwareTimer/Frequency_Dutycycle_measurement/Frequency_Dutycycle_measurement.ino) and as I said ...

Hello

I changed the pin from PB0 to PB3 and the example worked, why was this? I would like to know in order to learn. Thank you.

Regards.

Hello,

Just today I was investigating that, having found in ST that model of microcontroller. Thanks for the information!

Hello

Thanks all for reply.


Not every pin can be used.


Which pins can I use? I have modified the code by assigning Timer 3 and Timer1, but it still doesn't work.

HardwareTimer *MyTim = new HardwareTimer(TIM3);

If you cannot use interrupts ...

Hello!

Thanks for the reply.

I have oscilloscope and frequency meter up to 40 Mhz.

I put a 32,768 Khz crystal on the chip, but I removed it because I didn't see any improvement in the code nor could I (or did I) configure it correctly.

Hi

Is it not possible to do this with stm32duino?

Thanks

In STM examples you have example that reads frequency and duty cycle.


I have tried that example, changing the pin to the pin I use on my board (it was a gift) and it does not work.

[19:22:28:154] Frequency = 0 Dutycycle = 0
[19:22:29:161] Frequency = 0 Dutycycle = 0
[19:22:30:152] Frequency ...

Hello,

I want to read a PWM signal and know its duty cycle, for this I read a digital input and by pulseIn, I get a value that I divide by 10. It has been working, but I have noticed that if I raise the frequency or lower it, the value returned by PulseIn is altered, sometimes unrelated. For ...

Hello,

I am new to the forum and I have been looking for information about my question, I have not found anything, but maybe I have searched wrongly, I apologize if my question is duplicated.

I have developed some boards with a stm32g030 microprocessor, which I put some 48 Mhz quartz crystals and ...
