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 would like to know why when I sent the 202 bytes from pc to dev-board via USB HID, the buffer size would only get 32 byte each time, (byte[0]-byte[31])*several times until finished print out all 202 bytes?Couldn't it recieved whole 202 bytes the...
Hi everyone,I'm trying to drive a WS2812 LED strip (20 LEDs - Strip has 60 LEDs) using an STM32L432KCUx, but so far without success.I've tested multiple approaches — PWM with DMA, SPI-based encoding, and bit-banging via GPIO — but none of them produc...
Hello,I'm new to STM32 and trying to learn exciting stuff. I want to light a single LED from my WS2812B strip. For example I will choose 6th LED on my computer and 6th LED on strip will light up.But I'm not sure where to start. How can I access to si...
i am trying to implement openBootloader for an stm32l451,but i cant get the write to work i get the following errors HAL_FLASH_ERROR_PROG | HAL_FLASH_ERROR_PGA |HAL_FLASH_ERROR_PGSi am trying to write to 800c000 in the flashthis is my code( i used ht...
Hello all,I allow to send this message after a long attempt to perform a switch bank on my STM32U385RG.This is part of my code:/*--------------------------------------------------------*/ void OptionBytes_SwapBanks(void) /*---------------------------...
Hello, I'm using lwIP and I try to change DEFAULT_THREAD_STACKSIZE But where it applies ? I have my code under version control but I don't see any change ... and I don't see "lwIP" thread, maybe EthIF ?
Hi team, I am using STM32F7 for my work, am facing one issue regarding USB CDC Class, whenever am using it without enabling this macro everything is working fine, however as soon as i enabled this macro system will stop working itself, i...
Hello,I'm experiencing strange intermittent failures using STM32U575ZIQ using SPI and related DMA. MCU SPI setup: slave Rx-only mode, with slave select HW signal.SPI from the master (AD7768 ADC) shows 4MHz clock active all the time (even when there i...
Hi Everyone,I am currently working on a project that involves interfacing the "AT21CS01-STUM10-T" 1-wire EEPROM with the STM32C011F6U6TR microcontroller. I aim to implement read and write operations between these components but require guidance on th...
Hi,1. [Part Number] NUCLEO-L432KC2. [Environment] STM32CubeIDE 1.14.13. [Schematics] NA4. [Details] I am trying to measure a fast pulse with the ADC (~3 us rise time). I would like to trip a comparator when the pulse starts to rise and then start an ...
