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...
Hello, I'm using a STM32U5GJ-DK1 with the same SPI setup, I can measure the SCK output on SPI2, but I can't do it on SPI3. *This post has been translated from Chinese to comply with the ST Community guidelines.
Dear ST Community I recently purchased two sets of Nucleo-DRP1M1+NucleoG474, and now I want to implement FRS functionality on these two boards. Currently, I have set one of the default power roles to Source, enabled FRS_TX, and the other to Si...
Posted on January 16, 2018 at 15:48In RM0390 rev.3, in Figure 347. SPDIFRX States, sync_done internal signal is mentioned (and nowhere else). Isn't it the same as SPDIFRX_SR.SYNCD, at least from the programmer's point of view? If so, please replace ...
Hi there, follow the attached picture, an easy question for you, for me an effort. left side:Compiling procedure for a simple 32-bit binary file, ARMright side:program code - board LED should turn onresult:turn on LED - failed Questions:AIn my opini...
I'm trying to develop an application for the STM32H750 using USBX to implement two classes on the same USB device: CDC ACM and MSC. I've managed to get each one working individually, but I'm having trouble combining them. When I connect it to a PC, n...
First of all I am not sure if this is the right location. It wasn't: you posted under MPUs; moved to MCUs.I have a custom PCB with an STM32H5 chip embedded.This PCB needs to be a USB Host for a sensor that uses USB. If I connect the sensor to my lapt...
I'm trying to trigger ADC using an high resolution timer with period 500 KHz. The board is STM32F344. ADC is using DMA. I'm using FreeRTOS CMSIS V2. System clock 64MHz. So, two issues immediately came up: 1) After launching the timer using HAL_HRTIM_...
HelloI have a custom board with a STM32H730 and SD Card connected to the SDMMC peripheral, quad lines. I'm using the FatFs file system as added in CubeMX.My question is why does the file write rate drop after the first file (open/write/close) unless ...
Hello everyone, I encountered a problem while using STM32L431 for RS485 development. I used the ISO7041 isolation chip, and in the initial state, the DE pin is low, while both TX and RX are high. The current issue is that when I turn on the power, re...
hi, im using stm32g474vet6 tim_bkin for pwm shutdown through external pin, when im normally using pwm only tim break interuppt is happening, pwm is shutting down but if im using same timer in triggermode for another timer and pwm generation, tim_brk ...
