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 have STM32L4S5 (STM32 Discovery Kit - IoT mode), Part number: B-L4S51-IOT01A.https://www.st.com/en/evaluation-tools/b-l4s5i-iot01a.htmlThis is the first time I am using this device. When I plug this device into Windows 10 machine, I am not able...
After each project update, CubeMX 5x/6x changes the values of all USE_HAL_***_REGISTER_CALLBACKS definitions in stm32h7xx_hal_conf.h header file. This makes it extremely difficult to use the callback functions.PS:Hi, today I lost the whole day to fin...
Hello,MCU: STM32F429ZI I am building a bootloader for my project to upgrade the application firmware from SD card.Everything works fine but the total time for a ~2MBytes .bin file is almost 45 seconds. So, i am trying to check each step and try to re...
By default, when using HAL, it is required to set another time base source instead of SysTick as it is used for freeRTOS, but when using LL for all the peripherals, it shouldn't be necessary as LL does not use SysTick interrupt as HAL does.I think th...
We are still waiting for USB Host Hub support (will it ever arrive?) but in the mean time I'm trying to understand how some keyboards with built in touchpads work but others don't. Obviously, if they have a built-in hub and the keboard always connect...
I need to know HAL library version number during device firmware build process. Is there something like __HAL_VERSION_1_9_0__ or similar defined in the HAL library code?Thank youDan
I've been working with STM32F407 httpd POST for the last week. I've got everything with the POST working but I have one problem that I can't resolve. I don't know if it is a C problem or an LwIP problem, but I suspect it is LwIP.I have code that I se...
I am trying to implement a procedure to update firmware in a STM32L476 by jumping to the bootloader from user code. I am able to connect Boot0 to 3,3V and enter the bootloader just fine. But trying to jump there from user code seems to be giving some...
I am trying to implement the DFU on STM32. So taking the following project as reference.Everything working well.DfuSe_Demo_V3.0.6STM32Cube_FW_F4_V1.25.0\Projects\STM32F429ZI-Nucleo\Applications\USB_Device\DFU_Standalone\SW4STM32But when I reallocate...
