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 need few clarifications for reprogramming using internal DFU bootloader with Boot0 pin:1) Can I connect Boot0 pin to any other GPIO and that GPIO will drive Boot0 pin. Initially on power ON, GPIO pin shall be pulled up so that Boot0 is HIGH, ...
Question about the above PWR_LPSLEEP example code.My test setup includes this:* STM32CubeIDE Version: 1.17.0, Build: 23558_20241125_2245 (UTC).* HAL library STM32Cube_FW_G0_V1.6.2.* NUCLEO-G0B1RE.The example code in main() reduces the clock frequency...
Hello everyone,I’m working on writing a driver for the STM32F411RE microcontroller and have a question regarding the SYSCFG register map. I’ve been referring to the STM32F411 Reference Manual (RM0383)https://www.st.com/resource/en/reference_manual/rm...
I am using two ihmo2a1 expansion boards with STM32-Nucleo-F401RE to control 4 stepper motors. When I stack one expansion board on another. The signal given to the first board is transmitted to the second board. I removed comments to define the second...
Hello,I want to interface the ATWINC3400 Wi-Fi module with an STM32F7 MCU using SPI. Has anyone successfully done this before?If yes:What are the key steps to make it work?What modifications are needed in the driver files?Any example projects or guid...
I am trying to use the PLL1 fractional PLL on a Nucleo-U545RE-Q board to fine-tune a frequency measurement. RM0456 rev 5 has the following procedure to adjust the fractional PLL:"If the application intends to tune the PLLx frequency on-the-fly, then...
While working on a FLASH writing routing I got stumped with a bunch of flags being set in the SR register. It starts with CFGBSY. reading through the forums someone said they encountered this while accessing an uninitialized pointer. I found that I w...
I am using a nucleo-wl55jc1 and I've attempted to setup the example from this tutorial: https://youtu.be/OPrcpbKNSjU?si=mj6qIDGve6GwYWs6However, when I set the timebase source to anything other than SysTick to avoid the warning produced by the cubeID...
Hello,The following code compiles, but doesn't give the me results I'm expecting: void syslog2(uint8_t pri, const char *fmt, ...) { va_list args; va_start(args, fmt); printf(fmt, args); va_end(args); } main() { printf("%s\r\n", _tx_version_id)...
Hello,there is a race condition in the function SD_read() in the template file used by CubeMX when using FATFS with DMA template (sd_diskio_dma_template_bspv1.c).if(BSP_SD_ReadBlocks_DMA((uint32_t*)buff, (uint32_t) (secto...
