STM32 MCUs Products

Hello. I modified the .ld file with the aim to include another .ld file using INCLUDE "..\Mem_aux\MEM_0.ld", but at the beginning it's works, but when I modified the second file the changes didn't modify the memory layout.

There are any way to each time that I build the project, the changes made at the second linker script will be done? The main linker script is STM32F746ZGTX_FLASH.ld, and the other is called MEM_0.ld, and it's in another folder inside the project. Tha...

STM32H7 · Coding within HAL ISR inserts delay

Hello, all. First of all, thank you for taking your time for reading this and helping me out.I am using STM32H743ZI Nucleo board, preparing the project for a power electronics application. Before any control algorithm I'm checking that the Interrupt ...

STM32L031, VREFINT error depending on prior channel voltage.

I am using a STM32L031 on a Nucleo board to sample analog inputs and VREFINT. When I sample the VREFINT voltage after another channel I observe some error that changes depending on the voltage on that previous channel. I assuming that charge is being...

Need help to solve a problem with SPI bus of the NUCLEO144-H743Z2

Hello,I have a problem with the SPI protocol (NUCLEO144-STM32H743Z2 board) in a very specific case.The MCU first sends a byte array as a command to the device on the PIS bus, this device interprets the sequence and, depending on the content of the co...

Creating two task with one as realtime and second as idle priority, but as both task execute for say n minutes, program counter does not come into the task again, even you have a infinite for loop in both task.

MCU upgraded from STM32F103 to STM32L475. Facing issue in ADC part. In the F103 MCU ADC clock derived from HCLK and to meet the same sampling time we used ADC clock PLLSAI1 in L475.

The issue is that at the normal conditions we are able to read the ADC values properly and when we put our device in the field then we are facing noise issues in ADC values. When we put old MCU no noise issue is coming but when we put new MCU then no...

There is an error when i debug my code in the stm23CubeIDE.

When I go to debug, there is an error saying some source file isnt found (__lib_init) or something like this. I dont remember the name exactly. Then it gives me an option to go to preferences. Also, the debug doesnt run properly, my peripheral regist...
