I am building a project with two motors with hall sensor quadrature encoders so the QEI module looks very useful but for 18f4331 as far as I understand there are just two channels for a and B signals on RA3 and RA4, but I need to run two motors ie 4 pins which I would expect is quite common. Have I missed something and there is the possibility to run more QEI capture channels or should I forget the QEI and just write the code to just use the other A/D pins?
