HiI am trying to make an analog synthesizer, and for this is using a STM32G431 with some 8-channel DAC’s (connected via SPI) for generating control-voltages for the VCA’s and other circuits.I would like to use the SPI with DMA, and have looked at the...

Thanks for the suggestions. Will have to look for something more powerful than STM32Although I don’t need 48kHz sample rate, like in a music player application. Something between 10 – 20kHz will probably be fine, but needs listening to the analog cir...

Hi @AScha.3No misunderstanding at all, I think:)I’m in the process of building it, but far from finished. Analog circuitry is done, but have only recently begun the digital part.It’s only analog. The DAC channels are connected to voltage-controlled a...

Hi @IssamosThanks a lot for helping.It looks like a good simple example (with all relevant code in main.c, compared to 50+ files in the Discovery board example previously mentioned). Also like it uses LL library, which can easily be converted to dire...
