Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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 ST Team, I developed a custom USB DFU HOST class on an STM32F446ZE. I soldered a USB-C cable directly to the D+/D-, 5V and GND pins. The Problem: The stack works correctly for transfers up to 128 bytes. However, when I set phost->Control.setu...
Hello everyone, I'm having some trouble implementing I3C communication and would like to ask for some help. I am using the NUCLEO-H503RB board as my main controller. For the target devices, I have the NUCLEO-IKS01A3 expansion board and the TSC1641 (C...
I want to make a pedometer app that would count steps and display the number of steps on an LCD screen. I have tested my functions for the screen (ILI9341 SPI), and they work successfully. I tested the LCD code by initializing a timer that incremente...
I am migrating from STM32L431 to STM32L471. After migration, the function relating to internal flash writing does not work any more. The problem is when I programmed internal flash with HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, address, data), ...
I have an STM32H7A3ZIT running at 280MHz with 4 SPI buses attempting to “simultaneously” communicate with external ADCs. All 4 SPI are set up as full-duplex masters, 16-bit data size, 8.75 MHz clock speed, and software chip select.I’m using the HAL f...
Background: I am using the STM32H747I-DISCO board and the BSP SDMMC example from the ST Repository as my starting point. I can provide my code if necessary but wanted to keep post as short as possible. I have looked at AN4838, AN4839 and AN5200 ST ...
Hello,I am using an ST7701S LCD over 3-wire SPI (CS, SCK, SDA) with my STM32.When I send the initialization commands from my ESP, I noticed the following:The first command of the sequence is not sent.The program seems to stop at the second stage, ar...
Hello Everyone,I hope this message finds you well. I am currently developing a USB Host application using the STM32H573I-DK and have encountered a persistent Hard Fault issue that I would like to seek your expertise on.[Environment Information]Target...
I'm using stm32u535 and would like to have zero crossing detection of supply voltage. I've requirement of 6ADC channels and all are configured in differential mode and adc clock is 25Mhz and resolution is 14 bit and dma circular mode is enabled. On c...
Hi STM Devs!I would like to introduce a thread scheduling library - SuperTinyKernel (STK).Its GitHub repo: https://github.com/dmitrykos/stkYou can check capabilities in detail on GitHub but briefly STK can:Soft and hard real-time support: STK support...
