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 just bought STM32H735G-DK and USB is not working out of the box.I have put jumper on STLK but device is not getting detected on PC(LD6 red/green dim lit).There are no new devices in device manager when plugged in.Board is running original progra...
Hello all,I have worked through a number of issues with the SDMMC system and am currently stuck with not being able to reliably transfer from micro SD. I wrote test code to repeatedly read a file from the external card. In some cases HAL_SD_ErrorCall...
Hello All,Using STM32H743, I designed a board to use USART1 as the debug interface so that I could also bootload to this port. I am using an FTDI chip to create a virtual COM port. The problem is that I swapped the TX/RX pins in the design and had to...
Hi advancedI have a question to ask everyone. I use STM32F072 and use VCP to communicate with the GUI on the PC side.But it is very strange. If STM32F072 is not connected to USB, it will not work. It seems to be stuck and did not continue to execute ...
Hi,I am working STM3240G-Eval Board. Integrated LWIP and able to ping without any issues. Followed the FSMC_SRAM_DataMemory example to change the data memory sram and I am able to allocate variable in SRAM. Now the issue is not able to ping. Please h...
Created a new STM32 project for STM32G030K8 without modifications, when i run the debugger debugger stops working after HAL_TIM_Base_Start_IT..I have selected TIM14 as timebase source as i'm using RTOS.Why does the debugger stops in a new STM32 cube ...
I want to implement a single functions that continuously controls two or more output peripheral all at once. Which is a proper way to achieve that?I'm working on G030C6 MCU.I have written a program that takes input from multiple sensors and based on ...
HAL_I2C_Master_Transmit_IT can be aborted via HAL_I2C_Master_Abort_IT.But how to abort HAL_I2C_Slave_Transmit_IT?There does not appear to be a corresponding abort function.If a callback complete does not occur, the software should be capable of abort...
