I am working on implementing the absolute encoder on the iddk eval kit.
Quadrature is being input to the QEP1 module through gpio20, 21, and 23. I changed the coder from using gpio 10, 11 and 13 because they weren't connected to the EQEP1 module because they were not connected to EQEP1 as the software expected.
The analog is sine/cosine appears to be running OK, pretty much what I expected but the quadrature is not. As soon as I run absincos_init() the QEP1 inputs to the f27389d are driven low by (it appears) the f27389d.
I can't find the reason for it. The iddk is set up to use adcc and adcd, but I rewired the controller board to use adca (14 and 2) and adcb (5 and 2), is this a problem?
Any thoughts or suggestions- I could sure use the help.
