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...
Helllo,I'm trying to communicate with USB module that exposes 3 virtual com ports if used under PC and Windows. It's AT command set based communication module.I'd like to connect to it over USB Host library on STM32F779. I have basic code running, mo...
Hi guys!I need to Burst write multiple values using DMA. The processor that I'm using is stm32F407. I found than the solution for this task is HAL_TIM_DMABurst_MultiWriteStart function, but it is missing in the HAL library. https://github.com/STMicro...
I am using STM32L496 Nucelo, CubeMX 6.1.1; FATFS, DMA SDMMC with FreeRtos. For some reason I have problems when it comes to using DMA2 Channel 4 with FreeRtos. When it is selected for SDMMC1_TX then I can mount SD card and read data without any probl...
Hi there, I wonder when I transmit the wrong data package from peripheral to memory, as the wrong size as I configured, where the offset pointer locates that the location for the next transmission is not at the start of the memory (memory 0 since I ...
I need to implement a single channel software triggered ADC scan in an interrupt callback paced at 10ms intervals, since the rate cannot be controlled in DMA.I never had an issue doing this with CMSIS, yet, HAL seems to be, well, difficult is the nic...
