I am using timer 2 for trigger DAC and GPIO to generate analog and digital values.own timer 2 started with DMA to change ARR by an array.My GPIO array works well and starting to change from index 0 . but my DAC array start from Index 1. as you can se...
Hello,I followed a tutorial on how to generate a SINE wave using DAC and DMA that was really good. Logically it makes sense, you set up the DAC, set it to be triggered by a timer, then set up the DMA channel, set it to circular, and set it to use a t...
Hello I am working on stm32h745 controller, I am configuring the DAC SPI . For the DAC minimum frequency is 80 MHz. I want to set that frequency for SPI4 , but uanble to set how I can set the 80 Mhz frequency to SPI4. How can I set that if I set th...
Using STM32F765VG6TR, every time I power on the MCU, the two DACs are supposed to be set to constant output voltages of 2.4V and 0.8V. This happens inconsistently - sometimes it works, about 50/50 success rate. A few notes:If it isn't working, an MCU...
STM32CubeIDE v1.9.0 (and 1.8.0) is generating MX_DMA_Init() AFTER MX_DAC_Init() and this causes the functionality (DMA driving data to the DAC to play a wav file) to fail.
I tried DMA_SetConfig after __HAL_DMA_DISABLE and clearly it is not enough.Incidentally my intention is not change the size of the DMA allocated area - rather the size of this region accessed by a peripheral
STM32F334 DMA + DAC.After CubeMX: MX_DAC1_Init(); MX_DMA_Init(); MX_DAC2_Init();DAC2 working, DAC1 don't workingAfter editing: MX_DMA_Init(); MX_DAC1_Init(); MX_DAC2_Init();DAC1 and DAC2 working.The same for STM32F103. MX_DAC_Init(); MX_DMA_Init();Er...
Hi everyone,I am using the NUCLEO-G474RE development board with STM32G474RE MCUThe ioc file is attached, and this is main function:int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Configuration-------------------------...
Hi there!I am trying to create a lock-step synchronization between a timer that updates GPIO and a dac.As you can see from the below, the GPIO leads the DAC transitions by 1 cycle, and that's not what I want: My setup is as follows.TIM8 generates a T...
