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...
Hi,I'm using an STM32H723 and store my configuration data in flash. Here The procedure is: erase the flash once, then write to the erased flash. On read check the flash for a magic word to find where data have been written. Next write happens the sam...
I've set up my STM32U5A9J-DK to use ThreadX and connect to my PC via USBX and Audio Class.I'm correctly see the Audio Device on my PC and I can easily stream audio to it. The only thing is that, for some reason, the callback for new frame done is not...
I am on an H562 and trying to rd/wr a file on a USB memory stick using the mass storage controller. I am trying to understand what to do about this block when I am running in standalone mode. I started from an example code which is in RTOS mode but I...
In the above image (logic analyzer) , SPI in DMA was supposed to start at the end of high on the second signal, but it starts a bit later. (3rd signal CS of SPI, 4th signal SCLK)And the SPI was to supposed to be active at every period (the first sign...
Hi everyone, dear.I have already managed to generate the necessary strings that represent the html pages, but I need to generate more complex pages. In the example that comes with CubeMX, it simulates a file system. How can I convert a small file str...
Hi,We are running a crypto key generation library on both an STM32G474 (170MHz) and an STM32H563 (240MHz).Over about 80 runs, the average generation time is around 12 seconds for the H5 and 38 seconds for the G4.These times are fine for our applicati...
Hi I am trying to migrate my code from SPL(old version) to HAL based code I have conveted the same setup code to cubemx to generate the init function and I am using a clrc663 IC(card reader) along with it when the Ic Generates an interupt the mcu do...
Hello, Using Modbus master and slave communication, where Modbus master working fine, I have issue with slave device communication. Using HAL_UARTEx_ReceiveToIdle_IT() for receiving modbus frame, and HAL_UART_Transmit_IT() to transmit response. Curre...
Hello, i created a custom external loader for a STM32F429 board.The problem is now, my code needs HAL_Delay() for generating short delays between flash device accesses. And the code freezes when executing HAL_Delay(). So i have read that interrupts a...
STM32 MCUs hide surprisingly useful hardware features that can save you CPU cycles, lower power, make multi-core life easier, and fix intermittent bugs — if you know they exist. This article reveals 5 “hidden” STM32 features (with concrete examples ...
