Hi all!,I notice a different behavior from CubeMX, when starts alone or is called from CubeIDE.When I open CubeMX without CubeIDE, it works as espected. But when CubeMX is open from CubeIDE, it works in a strange way. Per exemple, when I try to put a...

Hi all!,I have 2 STM32F103C8T6 connected by CAN bus.Each STM32F103C8T6 has the same firmware.This firmware starts sending a message "RequestID" by the CAN bus.Is there a way to avoid send the "RequestID" in case another "RequestID" were detected on t...

Hi all,Here is a CubeIde project for an external loader working over SPI interface (not QSPI).It runs over a BlackPill board with a W25Q32 flash (the BlackPill has a place reserved to solder the flash ic).https://github.com/JLuisAlcaraz/STM32F411CE_B...

Hi all,I'm learning about low power modes , and I'm testing the RTC wakeup timer function.Datasheet talks about to set the IRQs for WakeUp timer on EXTI(IRQ 19) and NVIC(IRQ 3), but I tested in my code, with and without set these IRQs and the wakeup ...

Hi!, And thank you for yyour fast response.Yes, you're right. If I uninstall/reinstall, the problem disappears, but after a time I have again that problem. It happened to me a bunch of times.

I'm working with a custom board with STM32H7A.The custom external loader works properly from CLI, but cubeProgrammer fails to erase/flash/read external memory.But if...-Open CubeProgrammer.-Click "Connect"-After connected, go to "EL" and select your ...

I did it, and its work well. But the wakeup pin is only rising edge active, and I need a falling edge (yes, I can use a NOT gate, but if is there a way to use tamper...)

Thank you very much for your explanation.Do you have an example of wakeup a MCU, from standby mode, using a tamper pin?

CubeMX behavior when open from CubeIde.

CAN question with STM32F103C8T6.

A CubeIDE project about SPI external loader for STM32F411CE and W25Q32.

Hi all, I'm triyng to learn about TouchGFX and custom board. In the case you use a MCU without QSPI, like the stm32f411, is it possible to set memory mapped mode?
