With all due respect, Just because you don't see the application, that does not mean there isn't one

You are quite right, you don't understand my requirements. That is because what I am wanting to do is subject of a patent application ;) I can't use the DAC for this particular application ... I will just say, I NEED waveform modulated PWM to switch some high power IGBT's .. As for the ADC, I need t...

Hi There,

Thanks for that. I would really like PWM and A2D to be supported by DMA.
If I knew how all the pieces fitted together, I might offer to help ..

I noted the HAL driver layer, and see how that fits into the next layer up, but not sure from there ..

Cheers,

As I said, I intend to support DMA but it's a bit of work to implement so won't be done right away.

Hi Damien,

It's been a couple of years, is there any progress on DMA for ADC? ... or for that matter PWM?

Cheers,

Hi Guys, I am very new to microPython and Python in general (main languages are C and Forth). I have just installed microPython on the STM32Discovery board and it works fine. So what I want to do is to to read ADC into ram via DMA and also send a sine table in ram to a PWM channel via DMA. (I need t...
