I am working on a custom board with STM32F103CBT6TR. Initially, flashing the code resulted in a Hard Fault error, but now it consistently enters a SIGTRAP even after removing all breakpoints. Additionally, the GPIO pins are not toggling as expected. ...
I've got some trouble with the CRC unit in an STM32L475.At first, I got wrong CRC results, but then it dawned on me that the compiled code didn't force only 8 bits at a time into CRC->DR. So I added what I've used elsewhere, to force the compiler to ...
I’m choosing a microcontroller for a new STM32 design and I’d appreciate some recommendations.I don’t have particular requirements for compute performance, memory size, or ultra‑low power — just solid peripheral support and a Nucleo board available f...
Split from How to make the FDCAN with DMA - which is solved.TL;DR: STM32s don't support DMA for CAN or FDCAN.Hi, thanks for the clarity.But, the doubt I'm having was, then how to handle that much data rate like eg.5mbps in FDCAN without any help of D...
I have been using a STM32F469i Disco board to interface with a 800x800 LCD in MIPI DSI video burst mode. In order for this to work from the DISCO board, I have an adapter PCB to connect from the DISCO board to the LCD.It took a while to get going, bu...
Hello. Have some issues with MCU ADC configuration and data.Hardware: ...
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"....
