Hi,I have a custom board by STM32H743 and have some problems by RTC. I've used LSE with a 32.768 KHz external crystal. I have 2 or 3 seconds more in each minute. There is no reset within 3 minute and I see about 15 second more.I've used 6.8 pF for CL...
Dear all, the problem has been described in the enclosed video, please watch and advise. Since shooting the video, I have flashed the software three times and no change. I suspect, software is fine as many users are already using this board and same ...
Hello,I am building and application with a STM32U575 and a 4Gb NAND Flash. What I am trying to achieve now is to upload files from my PC through USB and then used these file within the STM32 using FileX.I already managed to set up FileX and LevelX to...
Hi Every one.When i am trying to write CS bit of RCC_CFGR register of STM32G491RE MCU to select HSE as a system clock (i.e 10) it changes to 11 (01 is default so i guess i am not able to clear these bits before assigning new value). Can anyone tell m...
I made a project with stm32h7 board, and use pemicro multlink to debug it under keil. I found it keep in systick handler pending but no active.I checked systick module register as:the counter is changed.and then I checked SCB releate registers asand ...
@Amel NASRI (Update: Comment moved here from STM32H745: DS and RM disagree, which to believe?) I've also verified that these errors still exist (though table/page numbers have changed) in latest docs ("DS12923 Rev 2 March 2023" and "RM0399 Rev 4 June...

hi,I am trying to connect ili9341 - STM32F722ZE FSMC- TFT but i couldn't succeed .ili9342 16bit - is working in direct GPIO 16 bit data PORT drive with STM32F722ZE not in FSMC-TFT . Looks most of the ili9341 working with FMC-TFT STM32F4 Series aro...
Hello STM32G0B1 For some obscure reason, sometimes the systick handler function is not called anymore.I mean, it works for some time then it does not work anymore. It looks like it is more likely to happen when I'm debugging but I have no factual inf...
