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 all,I am a newer STM32 programmer, and I have been working on the STM32H745 Discovery board for the last few months. Something that I would like to do is be able to switch into USB DFU Mode within a UI that I have made for this board. I took inspi...
STM32G473 via SPI I have most of the other commands working, but the Get Checksum command (0xA1) fails to return an ACK when I send the CRC init value. I am using the default CRC configuration:#define DEFAULT_CRC32_POLY 0x04C11DB7U#define DEFAULT_CRC...
Hello, I am developing a bootloader which communicates with an external flash memory (AT45DB041E) in order to check if a file is written inside the flash. This file that my bootloader is searching for is written from another program which is on the e...
Greetings! So, I used the OpenBootloader project, and then flashed a GPIO_IOToggle firmware in other area of the flash, close to the example in the video Introduction to Open Bootloader, Part 3: Loading an Application. In that example the CubeProgra...
Hi EveryoneGreetingsWe are using an STM32U585 MCU and need to maintain a log of about 200 KB using FileX. Once the 200 KB storage is full, I don’t want LevelX to reclaim the entire file and erase it. Instead, I need the log to behave like a circular ...
Hi, This might seem like a dumb comment, but I am reading UM1884, Description of STM32L4/L4+ HAL and low-layer drivers, and I find numerous references to "hal_ppp" or "HAL_PPP" such as the file name "stm32l4xx_hal_ppp.c" (Table 2, page 8) or "HAL_PPP...
Hello,I'm trying DUAL BOOT on STM32L471 and having a problem with SYSCFG->MEMRMP FB_MODE bit.I modified Dual Boot Bank Swap Boot Loader Example for STM32G4 project to fit my board, and everything goes well when the firmware put from the start of BANK...
Hello everyone, I've recently purchased the B-L462E-CELL1 cellular IoT Discovery kit, and I am looking for sophisticated libraries to control/run different sensors/modules on this board including the cellular connectivity modem, accelerometer, magn...
Each time I enable SPI, it works fine.However, whenever I include USART, SPI freezes, and this issue affects multiple chips I've tested.SPI and USART both work well individually.The problem seems to stem from CubeMX, which doesn't generate the code c...
