Can I use two DAC channels to generate independent signal on STM32H745

mosamasa · ‎2024-12-05

From a previous question: https://community.st.com/t5/stm32-mcus-products/stm32h745-dac2-missing/td-p/750749

So I can get two independent analog outputs using STM32H745?

Yes you can. DAC channels are independent. See this thread: https://community.st.com/t5/stm32-mcus-products/independent-dac-channel-triggers-on-stmf3xx/td-p/436595

You can use also DMA for both channels.

Two channels means you can generate two analog outputs with the same DAC instance.

Can I get for example sine wave output with 1kHz frequency from DAC_OUT1 and 2kHz sine from DAC_OUT2 at same time?

Hi,

Is it possible to have two independent analog outputs from STM32H745? For example 1kHz sine from DAC1_OUT1 and 2kHz sine from DAC1_OUT2 at same time using DMA?
