Arduino for STM32

When using the example code as is, it works to send a static duty cycle, but I do not know how to adjust the duty cycle while the code is running. Say I had a potentiometer and wanted to change the cycle from 25% to 50%. Is this possible? As it works with the example code (I mean PWM is output on t...

Do I understand correct that when the first value of bank2 is an SRAM address it is considered valid? Right. In Cortex M architecture, a binary always starts by Stack Pointer address, which should be in RAM. Thus 1st U32 value of your bank2 should correspond to Stack Pointer, and is considered vali...

Hi @Beuzekom, Explanations of Bank2 mechanism is detailed in Reference Manual RM0376 paragraphe § 3.3.2 Dual-bank boot capability So you need to take car of BOOT0 pin. There is also an application note corresponding to your needs: https://www.st.com/resource/en/application_note/an4767-onthefly-firmw...

Hello @capotti, I tested on my nucleo_G071 which is close to STM32G030K6T6 (no differences regarding UASRT) And your sketch is well working, output is displayed on Arduino serial monitor (through an external st-link connected to PA9/PA10). Just to be sure, can you confirm the following: * your USB t...

Hi @mkals, Yes, it is normal: CubeMX generates static initialisation code, but you miss the dinamic part of code to start the timer. Something like: HAL_TIM_Base_Start(&htim2); That being said, there is an alternative of using STM32 HAL to get a timer running: Have a look at New HardwareTimer st...

Great !!
Thanks for the feedback

Hi divner , Yes, things have changed around timer since version 1.8.0 We now have a more complete HardwareTimer driver available. Have a look to wiki: https://github.com/stm32duino/wiki/wiki/HardwareTimer-library and especially the example section https://github.com/stm32duino/wiki/wiki/HardwareTime...

Hi @RCP1990, As you defined NUM_DIGITAL_PINS in variant.h, I can guess that: * either your variant.h is not included at all (maybe another variant.h file is included, not yours) * or you didn't defined ARDUINO_CANFILTER_STM32 (which prevent definition ofNUM_DIGITAL_PINS ) this is the name of board i...

@geekfun ,
thanks for your feedback, and for sharing your code/schematics.
