How to write programs for STM32
I often write here that I don't use Cube/CubeMX. This sometimes rises questions, e.g. one forum member asked me off-forum:> What would be the best way to program STM32 MCUs ?> Don't you use the cubemx generated code ?> Have you some sort of good guid...
Is bank swap on STM32H753 immediate, instead of after reset?
I'm writing in-field update code for the STM32H753, and according to the reference manual (RM0433, Section 3.3.13) the FLASH memory bank swap takes effect only after a reset. But I wrote a test program that seems to indicate the bank swap actually h...

VGA not working?
I am trying to give 800x600@56hz vga output with my stm32f103c8t6. For some reason I can't get it to work. Both of the monitors I tried are saying "Input is not supported" or sth along thoose lines.I know that they can work with 800x600@56hz. I have ...
Resolved! Memory Mapped QSPI reads nonsensical data
I am using a STM32F746zg uc connected to a W25Q80 Flash memory. In my initialization I erase a page then memory map the flash and then I read a pointer to that address. I expect to read 0xFF as the flash has just been erased, however I read 0x88. I'm...
