Have you seen the PRU Cookbook[1]? In chapter 7[2] I give a simple example of passing data between the two PRUs using xin() and xout(). It's a simple example, but a start.
BeagleLogic[3] has a better (and much more detailed) example of what you are wanting to do. --Mark [1] https://markayoder.github.io/PRUCookbook/ [2] https://markayoder.github.io/PRUCookbook/07more/more.html#_xout_and_xin_transfering_between_prus [3] https://beaglelogic.readthedocs.io/en/latest/ On Wednesday, February 27, 2019 at 11:48:00 AM UTC-5, [email protected] wrote: > > > Hello guys, > > I am trying to make an ADC using the PRU.
