I am trying to use tickless idle mode. But for some reason I cant go into sleepmode, the mcu instantly comes out of it. Before I implemented tickless idle mode in my main application. I disabled all interrupts but still for some reason I could not ...
We are trying to add built-in self-test capability to a program we are developing.Specifically, we would like to periodically check ROM and RAM. Are there any sample programs for those? [MCU] STM32F412VGT6
I'm using an ST-Link broken off from a NUCLEO board to program a custom board with an STM32G4A1 on it. The issue is that UART transmission only seems to work while the ST-Link is connected - probing the line with a scope shows no activity when the ST...
Hello everyoneI've hit a bit of a snag with my PCB redesign (V2) featuring an STM32F429ZIT6. While the initial version (V1) worked like a charm, some layout changes and component swaps (SN74ABT16245ADL to two SN74HCT245DWR) in V2 are causing issues w...
Hi,I need to service an external watchdog when a flash sector is being erased. The sector being erased is in the same flash bank where code is executed from. Before I try to jump and run from RAM I had a few questions.Where is flash stall discussed...
Hello,i have problem with custom board assembled with STM32F767BIT6. I'm trying to interfacing LCD-TFT DEM 800480K3 TMH-PW-N which is assembled by HX8264E, HX8664B drivers. I'm using RGB888 interface configured via STMCubeIDE filled by resolution 800...
Hi,I want to update multiple HRTIM registers with a single DMA request on a STM32G474RE. To do this, I am trying to follow this simple Getting started with HRTIM tutorial, which has a section "#To_go_further_about_DMA_burst" on the board "B-G474E-DPO...

Hi, I would like to know method and sample code storing data without erasing whole memory page. I do refer example FLASH_EraseProgram, but i have wrote program that almost finish up the flash memory, if i erase a page, a 2KB page, it will erase my co...
Hi guys,I could set MCU into bootloader mode manually by using PH3/Boot0, but I can't get trigger bootloader via SW... I did check previous posts, but somehow it does not help.HW setup: I have dev board with STM32L431. It has USART1 (PA9, PA10) conne...
