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...
When i observe the clk pin always high but sometimes, somehow that i dont know i can see clk pulses but really i dont know reason why. Also i am trying to communicate touch ic and it has change pin sense the touchs. This pin always high and when the ...
There are two typedefs in the 'stm32l1xx_hal_gpio.h' file: 'GPIO_InitTypeDef' and 'GPIO_PinState'. The first has a corresponding entry in the low-level drivers (stm32l1xx_ll_gpio.h), but the other one is missing.It looks like this in the HAL file:/**...
Hi,I have a problem with my application that reads messages from CAN.Sometimes, after wake up, I see rx error on CAN driver (I use the function GetLastErrorCode, that return error number 32(Form error)), this situation remains until I generate a MCU ...

Hello,when I load the application, everything compiles fine and its running. When I now connect my USB stick, it recognizes it, says on the touchscreen which vendor it is, how much GB it has, and so on. Now when I touch the screen to enter playback m...
What is/are the best document(s) should i use to improve my knowledge about USB Host HAL driver. I yet didn't find a reasonable explanation of how it works in detail ...Thank you !ps: Could you link to a good PDF about that ?
I create Custom hid and send 2 PC report usingwhile(1){USBD_CUSTOM_HID_SendReport(&hUsbDeviceFS, dataToSend, 4);}And... Device is frozen. Why? I am going inside HAL->USBD_CUSTOM_HID_SendReport... I see codehhid->state = CUSTOM_HID_BUSY;so USBD_CUSTOM...
hello, I'm trying to transfer a block of data from the PC via USB (with HyperTerminal) to my device card, but I haven't found a way to not lose data.Surely there is the possibility of controlling the flow of data coming from the PC arriving on the re...
I'm working on a project using a STM32F446 with a boilerplate created with STM32CubeMX (for peripherals initialization and middleware like the FreeRTOS with the CMSIS-V1 interface). I have two threads which communicate using mailboxes but I encounter...
Hello everyone!!!I get a problem with HAL_Delay function. When I use STM32CubeMX creat my simple project (blink a led with STM32F4 Discovery Kit) everything is OK with HAL_Delay() function.But when I creat a same project without using STM32CubeMX, HA...
