Hello, I have come across an issue with the RTC in my project. In my project I am using the following:- MCU:- STM32H743IIT6IDE version:- 1.19.0SDK version:- 1.12.1 I will discuss the issue here, I wrote a program that uses the RTC and print the curre...
Hi,I am currently developing a small application with a STM32U5 where I write a few bytes into flash using HAL_FLASH_Program(). All seems to work fine. Except I can only read the data back after I do a reset. I suspect that DCACHE is playing a trick ...
Good day folks,I have the DCMI camera interface on a STM32N6 streaming to the SDCard, and I am noticing that there are cases that the DCMI reports an Overrun when a SD access occurs at the same time that the Hsync interrupt was meant to occur.Digging...
Hello,In my project, I want to hold boot params in BKPSRAM so "Application project" can also write and read this section easily. If boot is needed, "Application project" will set boot params as required and after that it will use "NVIC_System_Reset"....
HI,I am working on a board using STM32H573V and have a working solution with UCPD detecting an inserted memory stick and running the MSC class. In an other part of the software I am using PC9 as an GPIO push-pull, low speed output and as soon as I se...
Hello all,I've designed a board around a STM32H743 (LQFP-100) and am running into the following issue.On 2 boards out of 10, the HSE seems not to start properly. The HSE_RDY flag is never set after enabling HSE. I have checked it's not in bypass mode...
Should each vdd pin of the stm32f407zgt6 read continuity like the blue pill on multimeter, are they internally connected within the chip or separated? Similary for all the vss pins are they also all connected vss inside stm32f407zgt6 Thanks
Hello everyone, I am Li Weiwei (李炜炜) from a company based in Shenzhen, China, specializing in integrated circuit testing equipment and related R&D. We are currently working on a small-scale R&D / prototyping project that requires the STM32F103TBU6 (...
I tried doing an OBD2 request via Car's OBD2 port.I am able to see the CAN BUS traffic using an oscilloscope , just my request frames are rejected by car. I am using STM32h735G-DK development board to send OBD2 requests. It consists of an inbuilt FDC...
There is something strange happening with STM32N657x0HxQ MCU when HAL tick timer is not using SysTick, but a timer like TIM6, and TIMPRE is changed to 4 or 8 while timer is active. Observed it on DK and custom board.I created isolated test code with ...
