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...
Greetings Everyone.I am trying to create a Firmaware based on F0 (library 1.11.3) to MASTER ONLY READING using the I2S protocol.I have an IC which sends a DATA READY and only waits for a clock pulses to shift-out the complete data (24-bit frame). The...
I try to change the option bytes of a STM32G070R from my program. i think I did everything a written in the doc:clear FLASH_CR_LOCK with the FLASH->KEYR sequence and wait till it is clearclear FLASH_CR_OPTLOCK with the FLASH->OPTKEYR sequence and wai...
Hello everyone, who ever worked stm32f7 with flir lepton 3? I did it with flir lepton 2 but with flir lepton 3 it didn't work. I have problems with synchronizing segments (1 frame = 1 image = 4 segments). I have read the lepton3 documentation and can...
When I configure a project to use Azure, the SysTick_Handler is implemented in assembly, which does not call HAL_IncTick(). However, the initialization in main uses the HAL_Delay(), which never gets updated with the tick-time. I was able to work arou...
Hi,I know that DMA can save CPU time by transfering data from memory to peripheral (and from peripheral to memory) but it not clear how this works for I2C since the I2Cx_EV_HANDLER is still called when I changeI2C from IT configuration to DMA configu...

Reading the UM2524 user manual, I noted the following statements at page 14 The phrase "A training script for HAR is provided in the Utilities\AI_Resources\Training Scripts\HAR folder along with a Jupyter Notebook to explain all the steps taken." is ...
Dear ST/reader,I’m currently implementing a uart receive interrupt function for use with the STM32H743 specifically using HAL_UART_Receive_IT(). This is straightforward when the receive length (number of bytes to receive) is just 1 in which case it e...
Hi,I am working on a project where I need to add an info bar above multiple screens containing a digital clock.The digital clock is sourced by the rtc of the mcu. For one screen I read the current time and date with HAL_RTC_GetTime/HAL_RTC_GetDate in...
Hello, I would love to add a USB storage device (USB stick) to my terrific new STM32G4 application.But I am frightened, with the STM32G4 USB device interface this is impossible?(or this there some way to come around this?)(or is there any possibility...
