Arduino for STM32

stas2z, the malfunction occurs even if the timer is paused. What restrictions do you talk about?

Hi, friends,


ive not tested it, but its so basic and shouldn't cause any issue
only if your are trying to use it in the interrupt hadler


stas2z, that is exactly what I am doing, trying to use your suggestion within an interruption routine. The strange thing is that during the execution of this ...

In fact, fpiSTM, I was using 5V on the pot when I realized that reading through the analog port stopped at a certain point. Fortunately, it did not damage the microcontroller!
Bakisha and ABOSTM, I will test the routine without pausing the timer, thanks for the suggestions!

Hi, stas2z,


if your output ports are not on the same port sure you need to write it one by one
but much better ti use array, loop and simple bitmath to not write A4 page of almost same copycat parts

uint32_t pins[8] = {PA3, PA2, PA10, PB3, PB5, PB4, PB10, PA8};
void setPinsMode(void) {
for ...

Hi ABOSTM,

I am viewing the potentiometer values on an LCD display. Even with the potentiometer at its minimum value, the board's analog input reads 10 bytes, certainly due to some residual resistance. So, stating 10 as the minimum value, I establish that this is my zero point.
The fact that I am ...

Hello friends,

I am modifying an example program for testing the TIM2 general purpose timer of the STM32L476RG board.
Just to check operation, LED1 is activated periodically by the timer. At the same time, I use an oscilloscope connected to pin PA5, which corresponds to LED1.
With the fixed timing ...

Excelent, stas2z, thank you again!

Hi stas2z,

Thanks for the answer.


first i need to dissapoint you saying that PORTx are atmega only, it wil not work with STM32


You're absolutely right!
In fact, due to the silence on this subject in the last days, I realized that I was wrong, relating things that are different (declaration of ...

Hello friends,

I would like to use a shield that I developed for ArduinoUNO on the STM32L476RG board.
In the original program, I transferred integer values ​​to the ports instead of triggering them pin by pin.
As for the ArduinoUNO PORTB, only the first six pins are available (corresponding to ...

Hello friends,

Thanks for the answers.
I'm using the STM32L476RG board.
The sample file I used initially is here: https://github.com/stm32duino/STM32Examples/blob/master/examples/Peripherals/HardwareTimer/Timebase_callback/Timebase_callback.ino
Then, I found the site https://www.arduinolibraries ...
