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 am using STM32H753z, now i am trying to access SD card but i getting some error in stm32h7xx_hal_sd.c file of static uint32_t SD_PowerON(SD_HandleTypeDef *hsd) API,s in this /* SEND CMD55 APP_CMD with RCA as 0 */ errorstate = SDMMC_CmdAppCo...
I am using a bootloader as STM32F405.Before Jump_to_application(), I want to keep the GPIO status in API, but what should I do?After the GPIO PIN is output "high" from the current boot firmware, it runs the jump_to_application().The parameters are in...
Hi! I am developing a project which uses the satel-Vl53l8cx. I found many examples in I2C but none in SPI.The only one would be in VL53L8CX_ULD_driver_2.0.0 but this one was coded for the X-nucleo-Vl53l8A1. A wiring is shown in AN5945 in SPI but in...
Hello Community,I'm working with an OV5640 camera module interfaced to an STM32 microcontroller, capturing JPEG images to store on an SD card. I'm facing a peculiar issue where JPEG images with (quality settings lower than 0x0C in the OV5640's JPEG C...
I have been using this solution to jump to the ROM bootloader and that is working fine. However, it only works if the chip is coming out of reset and none of the peripherals are initialized, FreeRTOS scheduler not running, etc. Basically the chip nee...
Hello all, I have not been able to get the DFSDM_AudioRecord example to work on STM32H735G-DK.I am using CubeFW v1.11.2 and Cube MX 6.11.1. Furthermore, I tried debugging and noticed that the DMA Callbacks for Half and Full complete are called. Then ...
HelloI tried to implement I2S on the chip in question to send the data acquired by the on-board ADC (I tried both 8-bit and 12-bit) with DMA active on a curved buffer and half-word data size. The data should be read by an ESP32, connected to it on th...
Hello,Are there any resources similar to AN3364, that describe the migration directly from F4 to F0?Thanks.
Hi,I am using a custom board integrating a STM32L071kzt6 MCU and have an issue to wakeup the MCU with uart start bit detection if the MCU uart rx line was no more pullup by the device with which the MCU communicates (A FT230XS USB to RX bridge).It is...
AN2606 does a very good job of describing communication peripheral usage by the bootloader, but not so much GPIO pins.Can I get a description of how each of the GPIO pins on the ST32U545REI6Q is configured by the bootloader? This could be important i...
