So I fired up CUBEstarted ADC over DMA with circular mode and Half Word to memory then I added Continuous DMA requests and set TIM5 as trigger sourceI then set up timerADC is 12 bitsthen I started everything and this happenedhowever I do not understa...
Why should I clear the DMAR bit in the UART DMA receive interrupt subroutine?At the moment I disable the DMA TC interrupt and the DMA Mode for reception (DMAR) at the top of my interrupt routine.At the end of the subroutine I enable the uart dma rece...
Hello,I'm working on a project on STM32F769 DISCO Board in which I need to read and parse data from a .json file (3kb). I tried using Nlohmann JSON.hpp library for data reading and parsing and, even if I do not have compilation problems (except for a...
We are using the STM32F746ZET6 controller in our project.We are facing some issues, When we put the integration code to the controller we observed that the overall process of the controller is delayed.One use case is integrated code: we run the PWM w...
I'm using a Nucleo L152RE.I've read the 900 pages manual multiple times but I still miss a clear view of what needs to be done to create a RTC Wakeup event. I read in the manual:"""To enable the RTC Wakeup interrupt, the following sequence is require...
Hello all,I want to use STM32L072 in Stop mode. But, it should receive interrupt UART interrupt while being in the stop mode. It is not receiving UART interrupt while being in the stop mode. Can anyone please explain the reason and the ways to solve ...
Hi at all,Sometime happens that usart2 irq freeze and HAL_UART_RxCpltCallback isn't called.From this moment I can send data (I use blocking instruction HAL_UART_Transmit), but don't receive any.When this happens, HAL_UART_ErrorCallback don't called t...
