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 guys, i am at a complete loss; even with describing the problem.I have a 6-layer board with the USB3300 directly underneath the H750(100Pin LQFP), so traces are short and basically optimal. I use CubeMX to generate an example -> I use MCO2 as 24MH...
Hello Dears, the last update from ST related to tickless mode for AzureRtos was back in January 2021, here, is there any new update on this? I'm asking specifically for the L4.It isn't obvious to have the option in CubeMx when the feature is not full...
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...
