Greetings all;
In my first attempt with pics and more practice, I was able to program the 4x4 LED matrix to work well (see picxie). http://www.larwe.com/zws/products/picxie/index.html
Now I want to do the 8x8 matrix (see picxie2) but need a little code help using picBasic (not picBasic Pro) to write a PWM to RA0 and RA1 ports to send to the 74HC374 chips. Can someone clarify the connections of D0-D7 on both the 74hc374 chips to the B0-B7 ports of the pic chip.

Thanks everyone
