I'm trying to make use of the HAL_UARTEx_ReceiveToIdle_DMA() functionality.So far no reaction on an IDLE event. The corresponding HAL_UARTEx_RxEventCallbackgets called when a certain amount of bytes has been received, but not on an IDLE event.The dev...

I'm trying to receive data from the LPUART1 serial port on the L031K6 development board.Unfortunately all my aproaches failed so far.Sending data works fine in all three modes:BlockingNon-Blocking ITNon-Blocking DMAI'm routing the LPUART1 to PA2 and ...

HI everybody,we're are trying to build up a few more work spaces for developing STM32CubeIDEapplications and we're unsure in what kind of laptop / desktop hardware we should invest.Can somebody point out the most important parts responsible in speedi...

Hi Guys,we have a document management system in our company.There we store all kinds of project related files like 2D drawings,3D designs/assemblies, test reports, datasheets etc..A quite useful feature is to click on whatever document and thesystem ...

Hi MClau.1,well it would probably help in your situation if you would show us some portions of the code that you use to handle DMA transfers.In general the ReceiveToIdle call activates three kind of interrupts:IDLE => Reacts on IDLE events and the ID...

Hi Karl,it was not exactly the reason but the right direction. In fact I missed to check theStatus of the HAL between two conscutive called DMA functions.Thanks

Yes, I am using the VCP. And I connected an oscilloscope with decoding functionality to monitor PA15.The terminal software to send data via serial line is PUTTY. And as I already mentioned, I know thatdata has been received, cause after exactly 16 By...

In the end I will use a ring buffer, cause that is from my point of view the most convenient way to handle received data.Ok back to the previous approach: I commented the line__HAL_DMA_DISABLE_IT(&hdma_usart2_rx, DMA_IT_HT);out, but no change. No cal...

Hi Karl,thank you for your post. The line__HAL_DMA_DISABLE_IT(&hdma_usart2_rx, DMA_IT_HT);should only disable the interrupt generated after half of the expected data has been received.According to certain threads and forum messages this interrupt and...
