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...
Dear all,I have a working camera + video encoder solution running with LCD display disabled.I have one preview thread that displays camera data on the LCD, this thread can be suspended and restarted. While the first run looks fine, the output has a g...
Hello STM Community,I am a beginner working with the STM32H7B3I-EVAL evaluation board based on the STM32H7B3LIH6Q MCU, and I am currently setting up my development environment on Ubuntu 24.04.3 LTS.I installed STM32CubeIDE 1.18.0 using the following ...
Hello, What HAL2 API can I use to turn on/off the output of a timer? In HAL (ver 1) this could have been done like this:TIMx->CCER &= ~TIM_CCER_CC1E; // Example for Channel 1: ~TIM_CCER_CC1E // or __HAL_TIM_MOE_DISABLE(&htimx); Thank you,-Gil
I've been using a nucleo l476rg with a LIS2DUX12 sensor and I need to use the SPI protocol, but came as a surprise that the MISO line is not working. When it's not getting 0xFF (should be 0x47), gets inconsistent values. Tried changing CPHA, CPOL, pr...
Hello my friends, I hope you are doing great.I am trying to create a custom driver for UART peripheral with CMSIS register header files.I have created a build system using the board files and linkers and make. So far I have been able to make drivers ...
Hi, I am using the STM32N6570-DK development kit and I want to flash my FSBL and Application firmware into external flash using USB. Currently, I am able to flash the firmware using ST-LINK, but I want to perform flashing through USB as well. I confi...
Hey ST-Community,I’m working with an STM32H7S78-DK board and trying to get Ethernet running. TouchGFX and FreeRTOS are working fine, but I’m stuck with lwIP. The task starts, but DHCP never succeeds (the printed IP is always 0.0.0.0). I also tried w...
Hello I am trying to implement I²C slave on a STM32U385RGTxQ in non-blocking mode, on I2C2.To match I²C standard I tried to use the Address macthed interruption but the interruption is never trigged. I used the function HAL_I2C_EnableListen_IT(&hi2c2...
I am not able to erase a section of internal flash of the NUCLEO-H633RE.Using the debugger I see the Flash is all 0x00 before I try to erase. I verify that Flash is not locked i.e.if (*FLASH_NSCR && LOCK) { *FLASH_NSKEYR = 0x45670123; *FLASH_NSKEY...
English language:STM32H7 Ethernet + DMA + Cache Explained + LwIP (EN) One of the most common sources of confusion when working with STM32H7 microcontrollers and Ethernet (via LwIP + HAL ETH) is data cache (D-Cache) behavior.When using DMA (like Ether...
