I struggled with the CMPM interrupt and made a small test programm to reproduce the bug.To see whats going on I use an oscilloscope with 2 GPIO pins called A and B.Pseudo Code:LPTIM_IRQHandler() { setGpioA; clearFlag_CMPM; resetGpioA; } main()...
I am trying to setup UART on an STM32L072CZTX. In the ioc file I have setup the pins, RX is set to AF4 pullup, and TX is AF4 nopull. The interrupt is set to 0 and enabled. I have redefined the RxCpltCallback in the main and have events occur in there...

Hello!It's been a while since my project is working fine with STM32H750, using HSI (+PLL) as SYSCLK and RTCC by LSE (crystal and capacitors selected by ST notes). But (maybe) after an abrupt reset by the power suplly, two of my custom boards starts t...

If yes some example for fft from ADC data . Howto max speed convert ADC array into fft input in CCMRAM , what is better f32 or q15?
Hello! I am trying to set up CAN for a custom hardware, but right now I am just trying to get CAN running by itself on a STM32F3Discovery. I attached the full code below, but from what I can tell, it goes as far as sending the message out, but all i ...
Where do the "Fast channel" and "Slow channel" texts belong to? To *pins*, or to *inputs to ADC*? If former, why are they not unambiguously on the left hand side of picture, next to the pins names? If latter, why are they only on every other input t...
I want to write some data into flash memory on STM32G071 MCU as a part of a project. For that, I am using the function 'HAL_FLASHEx_Erase' to erase the pages before writing. While debugging it's working fine. But when I downloaded the code to MCU and...
