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...
HAL_SPI_Receive_DMA() is non-blocking; it just sets up and starts a transfer. Is it safe to call it from an interrupt context?If it is (at least possibly or sometimes) safe, does it make a difference whether the SPI port is configured as SPI_MODE_MAS...
Hi, I am working on a project using STM32L152. I have ADC DMA set up as I've used in many other projects using this part. For some reason this time around ADC values are not getting ready by the micro, and when I debug I find the DMA1_Channel1_IRQHan...
I have created a bootloader and application. My bootloader appears to launch my application successfully; however, the interrupts are not functioning in the application. I used memcpy to copy the vector table into RAM. Below shows the results of th...
I know that they can not be used at the same time. But how can you switch between CAN and USB at runtime in the same application?
The example does not work. It times out:Stack:HAL_OSPI_AutoPolling() at stm32u5xx_hal_ospi.c:1,831 0x80042e8ospi_memory_reset() at lx_stm32_ospi_driver_glue.c:560 0x8001afelx_stm32_ospi_lowlevel_init() at lx_stm32_ospi_driver_glue.c:79 0x800165alx_st...
hello i am getting an unexpected error while flasing blinky code in stm32h747i_disco_m7(H7 Series).The code is built successfully but i am getting error while flasing. I have tried all possible solutions but eventually i failed so kindly assist me.I...
Hi everyone,I am using SPI1 on the STM32U575 to transmit data, and my issue is that between consecutive calls to the SPI transmission function, there is an extra long clock pulse instead of no clock pulse at all. This is my first time using the STM32...
Hello,I am currently designing a board with STM32H747AI MCU. May I ask how it is possible to run the RTOS on it and then program it via USB-C without using special internal components such as ST-Link MCU in order to save as much space as possible? Do...
I implemented IWDG reset having counter of 12 second and am refreshing it using HAL_IWDG_Refresh(&hiwdg) in while loop. Everything is working as expected. But now the issue is when I implement sleep mode. The processor will be in sleep and wakeu...
