Hello,We’ve designed a device that uses an STM32 microcontroller to manage various features such as I2C, UART, ADC, IWDG, DMA, Flash memory handling etc. After running smoothly for a month, the device began malfunctioning, drawing 220 mA of current a...
Hi, Using references from 1) STML496 UART Wake up from Stop Example - https://github.com/STMicroelectronics/STM32CubeL4/blob/master/Projects/NUCLEO-L496ZG/Examples/UART/UART_WakeUpFromStop/Src/main.c#L78 2) STM Getting started with PWR Guide - https:...
I have designed a custom board using STM32H573IIT3Q MCU. when I connected it with st link, the st link not recognize it. After I check the voltage on power pin, all the power pin is normal except the VCAP pin (not outputing voltage). According to the...
Is it OK to use these pins as current sinks for driving LEDs ?
Hello everyone,I'm using Board NUCLEO-U031R8 for testing now.I have an old FreeRTOS project designed for a power-saving application, and I am preparing to migrate it to a new IC STM32U031 series MCU.In the old project, setting configUSE_TICKLESS_IDLE...
We are working on a design that includes an STM32U545 running at around 1MHz to save battery power for the overall board. We have a requirement to write to an event log when the power is removed (this is the main operating power, not VBAT).The softw...
I have a STM32G030K8 processor that needs to write some stuff to memory as soon as it detects that it will be losing power - always a bad time but I have to do this.Most of the time it seems to be doing this just fine but once in a while the processo...
Hi, we are developing a USB PD sink device which will operate up to 28V @ 5A.The STM32G431 seems to be ideal for our application, however it seems that there is no official support for EPR within the TCPP software yet and I am unable to set a PDO hig...
Hello everyone,I'd like to request some help with an ECG Holter Receiver Board. This is my first time designing a MCU board.I am basing this design on this article from Analog Devices: https://www.analog.com/en/resources/analog-dialogue/articles/ecg-...
Hi everyone, I am trying to use LPTIM1 and I2C3 to read the values of a sensor's register every 1 second and save them into a data buffer while in Stop2 mode. What I would like to know is if it is possible to store data sampled at a given frequency ...
