STM32 MCUs Products

I am trying to setup DMA with ADC on stm32h747 even thoug conversion end DMA transfer never completes. The ADC's conversions are triggered by a timer (this part of the code works fine) and the DMA is supposed to write the data to memory.

Here is how I setup my DMA ; Enable Clock for DMA1Periph to memoryset memory and periph size to half wordset memory address increment and clear periph address incrementset circular modegive the flow control to the ADCSet DMAMUXSet DMA periph addressE...

Sync DMA request every 72 bytes based on GPIO signal

I have an SPI peripheral that generates an external signal (EXTI) when a data record is ready. The data is then read over SPI by the MCU. The data record is 72 bytes.Right now I have an interrupt handler that starts the DMA process to read the next r...

Does CAN Loopback test will send frames out from TX pin and we can monitor them either on TX pin or Transceiver H/L Vs ground connected. User manual refers to we can monitor Tx signal when scope is connected.

Why HAL_UARTEx_ReceiveToIdle_DMA stops working after unpluging serial line and then pluging it back?

I'm experimenting with bluepill, I have set USART3 to DMA circular mode. I've enabled the HAL_UARTEx_ReceiveToIdle_DMA in the main() and then again in the HAL_UARTEx_RxEventCallback, the half complete receive callback is disabled in both main() and i...

STM32h7 series controller have the option of SMP inter-process communication?

Hello,I am working on stm32h7 series for interprocess communication there is option of OPEnAMP for communication , stm32h7 have asyncronous architecture. There is option for SMP interprocess communication how we can do that?

STM32F469-disco CAN-display (I2C) problem

I declare that I am using a CAN library which works with other boards, so right now I’d like to rule out that’s the problem.Therefore, despite having configured the CAN and the code compile correctly, the messages are not received while using STM32F4...

Using 6 ADC channels and 3 DACs on STM303K8 , Nucleo-F303K8 board and STM32CubeIDE

I have identified from ADC1, 5 channels ( IN1, IN2, IN4, IN11 and IN12) and from ADC2, IN4 which i can use on the Nucleo-F303K8 board. I am currently only concerned with with the ADCs but will later add the 3 DACs ( DAC1/1, DAC1/2 and DAC2/2 ).How d...
