STM32 MCUs Products

Why does my LSCO output for my LSE have a delay in matching my LSE input.

I am developing on a STM32L4 product and was having issues with the CSS shutting down my LSE signal. I found this problem in the errata and turned the CSS off, but it forced me to look closer at the signal my LSE crystal was providing (using the LSCO...

Is DMA peripheral to peripheral data transfer possible in the 32L476rg MCU ?

HelloI am currently working on a project that requires pushing data directly from a uart rx pin directly to an SPI device (an external SRAM) tx pin One way to do it, is by using DMA , unfortunately most Stm32 MCUs do not offer a peripheral to periph...

Dear STMicroelectronicsI am an employee of the TaiPit company, we are engaged in the production of electricity meters. In modems for electricity meters, we use STM32L412CB microcontrollers and additionally some modules. At the moment, the task i...

What happens when GPIO is sourcing more mA than allowed?

My STM32F746 can source 25 mA per pin, but only 120 mA in total.What happens if we exceed that amount? Will there be a brown out, will the STM32 reset, or will the STM32 get damaged?

STM32H753 writing option bytes stalls execution

Hi,We are using an STM32H753 (revision V) and using the bank swap functionality to implement a firmware update system. To do this we need to write to the option bytes to toggle the bank swap bit.This process works but we have noticed that when the cu...

Hi, I have a brend new STM32L652 with tehe latest CubeIDE. When I try to program the MCU, the program seams to be loaded to the MCU but unfortunately I cannot debug it like I use to for other boards like NUCLEO. Do I have to configure something ? TY

Does remap of CAN1 pins work on STM32-E407?

I bought a few Olimex STM32-E407 boards lately. I need to use the CAN1 bus. However, the default PA11, and PA12 have not populated, and I remapped to PD0 and PD1. The code always failed immediately at CAN_init (generated by STM32CubeMX). No choice, I...
