Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hi, I am on stm32u585 IOT dev board for low power modes am using RTC wakeup the sleep and stop 1,2 and 3 are working fine but standby and shutdown is not working ? my code void sleep(int mode, int seconds ) { if (seconds <= 0) return; HAL_RTCEx_...
Post Edited by ST moderator to apply source code formatting Hi ST Community,I am using STm32U575VGTX. I configure RTC as default, enable RTC non-secure interrupt, activate alarm A trigger each 10 seconds as below: *******************************...
Hi,on STM32F429I-DISC the timer TIM2 kicks ADC1 and the data goes to buffer via DMA. APB1 clock for TIM2 is 36MHz, reload value for TIM2 is 143, I exspect 36e6/144= 250k samples/second.I get 8.3e6 samples in 123 seconds which results in 67.4ks/s. Thi...
Hello, I have a Nucleo-H723ZG that I am trying to setup a Continuous running ADC that fills a buffer VIA DMA. I have read tutorials, watched videos, looked at the data sheets and still can't get it working.Tools: CubeMX to generate code VScode to...
Searching through the forum it seems like there are tens of posts regarding this topic. I read many of them, but I struggle to find a solution that applies to me.First of, I use an STM32H743VIT.My goal: Use ADC1 and ADC2, one channel each. The two AD...
Hello,I implemented the How to use SNTP over LwIP and RTC with an STM32 - STMicroelectronics Community example (not using FreeTOS) in the suggested STM32H723ZG NUCLEO-144 board. The app runs, but when it tries to allocate memory for DHCP with the mem...
I am new to ThreadX. I have had experience with FreeRTOS generated with CubeMX.However, I have been starting over repeatedly with CubeMX. Just trying to create a base project with Nucleo-F767Zi.I need to find some documentation for starting this proc...
Hi, I'm using STM32F407 TIM1 channel 1 to measure the frequency of a square wave. The result is not accurate. For example, when input frequency is 1000.0Hz, the result is around 1006Hz. Input frequency has been verified by an oscilloscope, with probe...
Hello, i just wanna take a snapshot by STM32N6570-DK with IMX335. I am using SnapshotDecimation as my reference. after reviewing the code. i wonder why AXI RAM3/4 and RIF are necessary for this project i saw it in 'HAL_DCMIPP_MspInit' function, but i...
My question revolves around TouchGFX and firmware for accessing the SD card.I'm studying the STM32N657-DK and am already getting good results with TouchGFX. Now I need to write a module to read the SD card, count the files, and update a progress bar...
