DMA: ADC to Memory

[mattiekempen]

Hello,

for a while i've been trying to get my teensy 4.1 to work with dma. specificly DMA to Memory.
I want this running on 8Khz for audio purposes.
i just havent found any working examples.
the audio libary is no help because you can't set the sample rate.
are there any examples where i can find how ADC to Memory works with dma?

thanks,

Try the ADC library: https://forum.pjrc.com/threads/25532-ADC-library-with-support-for-Teensy-4-3-x-and-LC

Which versions comes with the teensyduino or you can download from: https://github.com/pedvide/ADC

There are examples like: adc_timer_dma

Oh, you can set the sample rate. Pretty easy. Wonder why Kurt did not mention it..
