STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
So I have three switches (nothing special just momentary push button) wired into the board PC2, PC3 and PA4. All are using internal pullups. PC2 and PC3 are set for rising / falling trigger IRQs and PA4 is set for falling IRQ. They all have their own...
I am working on a project where I have managed to detect any printer using USB driver provided by STM-HAL.All this code is developed on STM32F407VG MUC Discovery Board. Which is working fine and I am able to print the labels as i want without any err...
Hi all. I am aware that this topic has been discussed before here: https://community.st.com/t5/stm32-mcus-products/debugger-hangs-at-scb-enabledcache/td-p/640648 and here: https://community.st.com/t5/stm32-mcus/dma-is-not-working-on-stm32h7-devices/...
I'm using an STM32H750 MCU to run an application that communicates with a computer via USB in CDC ACM mode. The application uses USBX from Eclipse ThreadX and an external USB PHY (USB3300) to perform high-speed communication. My application works fin...
Hello evryone:at the first it is may firt project with STM32, and don't have any experince with this MCU.I have a problem, when I read (with HAL_ADC_GetValue(&hadc1)) the multi channel ADC value in interrupt mode the value is always the same. I have ...
I checked the datasheet and there is a memory map of 521Kbyte.But I use the stm32h523VCT6 chip.This chip has 256Kbyte of memory.Can't a chip with 256Kbyte of memory use bankswap?If it can, can you tell me the memory address?
The SVD files package available for the H5 family (here) does not include any SVDs for the H523 and H533 sub-families. Can we get access to those files?
Hello,I'm facing a very strange issue with timer PWM in DMA mode.I use the PWM channel to send step pulses to a stepping motor in order to free the mcu while the motor is moving, rather than using time consuming delays.The issue raises when I change ...
Hello, everyone,I am following the following youtube video posted by ST: https://www.youtube.com/watch?v=jE_nL1GObmA.My intention is to use an SD card to go and insert images due to a lack of space in flash or external ram.I followed the video, creat...
Hi, We are using the STM32U5A9J-DK board and are trying to achieve Read-While-Write (RWW) functionality. The flash chip we are using supports RWW. Earlier, as per [this post](post link), we learned that to achieve RWW, we need two OSPI instances, nam...
