I can produce a sine wave using DAC1 + DMA on a STMG431CBU6 MCU, but I'd like to increase the frequency (purely as a learning exercise).  In the application note https://www.st.com/resource/en/application_note/an4566-extending-the-dac-performance-of-...

I need to generate 3 PWM signals with the same frequency and referencing the same start point (so sort of synchronised) but with different duty cycles and delays before the pulse, like this:I'm using a STM32G474CEU6 MCU and STM32CubeIDE.I've spent da...
