First of all: I am aware ofhttps://community.st.com/t5/stm32-mcus-products/jitter-in-adc-dma-mode/m-p/231446#M51827but cannot see how the accepted answer solves the (my?) issue.Setup description:I useSTM32H723VGHxADC1 and ADC2 are setup inDual regula...
I am working with STM32H747i-DISCO board and I configured ADC1 with DMA1 stream0 and ADC3 with DMA2 stream0 both with Cortex-M7 core as initializer and I created the MDK-ARM project using STM32Cubemx and compile the code in CrossWorks when I debug t...
Hello,first of I must state that this is a bare metal project. If bare metal is not your thing then please do not read on. I only use parts of the CMSIS but no HAL and no LL.I have a strange effect when using I2C1 bus with DMA and USART1 with receive...
I have a couple dozen of custom boards with STM32G4s on them. These boards are all 'identical' and the software being loaded on them is the same. BOOT0 pin is currently floating so on my initial load I held it to ground and changed the option bytes v...
Hey there,another question. I can successful output 8 DMX universes received via Artnet using DMA (Mem->Periph). At the same time I want the possibility to receive upto 8 different DMX signals connected to the MCU. Therefore I hooked up the receive l...
Hello,I would like to use DMA with SAI but I am having difficulty writing the code. Can you check if my code is correct and why I cannot retrieve the RX values ? /* USER CODE BEGIN 2 */ HAL_SAI_RegisterCallback(&hsai_BlockA1, HAL_SAI_RX_HALFCOMP...
I am using a STM32F767BITx LQFP208. I have to measure 12 channels. 6 channels measure the voltage and 6 other channels measure the intensity. Samples from voltage and insitensities shall be done as simultaneously as possible.I am using ADC1(voltage) ...
Hi,We have a question about a system design we would like to implement for our product.We are working with the STMF32F723 MCU and are developing our own HW. We need 216MByte of RAM for our application and would like to implement it with the functiona...
Hi everyone Question: suppose one sets up a DMA transfer from a Timer1 register to memory so that it gets executed when timer event is raised. What happens first:the peripheral to memory DMA transfer is executed ?or the Timer registers are updated?...
I am reaching out to seek your expertise regarding the DMA transfer issue on SPI that I encountered while using the STM32H743 microcontroller.When an EXTI LINE 0 event (data ready) occurs, attached to the code is a program in which 30 bytes of 0xFF ...
