Hi,
I'm just informally playing with STM32CubeMX for the very first time and it seems pretty neat in that for a novice (if I'm even that) I can get code setup quickly.
I have a question though, I selected my board STM32F446RE and then explicitly chose to use DAC and DMA.
But it seems to want to also use USART2 and I have no idea why, what I was aiming to do was look at the generated code and use it to augment my already working test app that simply pumps a 4K array of pre-calculated Sine value to the DAC.
Test test app has been cobbled together from bits and pieces and books etc and works OK.
So is there something fundamental here? must a USART be used in some way when doing DMA with a DAC?
Thanks
