That's working now! Thanks
Is there a way to reload the DMA without rerunning the script?
The brief needs the program to run as a standalone where triggers on a GPIO pin play back wave32 from the beginning.

Re: Using DMA as a beginner
Been going through this for a while and am still unsure how to get it to actually send the voltages to the pins in hippy's code- it just seems to print the values.
I assume PioDac is the key but it doesn't behave like any function I've come across before.

Re: Using DMA as a beginner
V helpful thanks!
I'll try and get my head around it
I was aware of that post, my design is partially based off the instructable!

Using DMA as a beginner
Hello! Am attempting to construct a triggerable function (envelope for synthesisers) generator using a Pi Pico and Micropython. The Pico has a 7bit R2R DAC across GPIO 16-22. Have been successful using while loops and utime.sleep to play back lists of voltages but I find that there is an annoyingly ...
