Code is too simple, else is initiated by CubeMx, using latest CubeIde. Board is DevEBox.#define buf_size 512uint16_t data[buf_size]={};for(uint8_t i=0;i<(buf_size/4);i++)data[i]=4095;HAL_TIM_Base_Start(&htim6);HAL_DAC_Start_DMA(&hdac1, DAC_CHANNEL_1,...

Scope is showing half of data in "high" state, although if you take a look, that high level of signal is having square wave inside it that has wanted resolution from timer.As KnarfB pointed out, mistake was in setting up the DMA transfer, it should ...

YES, yes it should be!Thank you very much KnarfB !Completely overlooked that mistake... Now works perfectly with multiple waveform shapes!Thanks again!

Strange DAC behaviour on STM32H743VIT6 Hi to community! I have a strange problem with DAC. Whatever settings (buffer on/off, dma mode, data format or allignment, speed, etc) i am not getting simple output results that are expected. Thanks in advance!
