| Yes, I did succeed. So, I know the problem is in how I am addressing. I was hoping I could just set Enable to HIGH or LOW and have that do it, but apparently not.
Thanks. //Cynthia |

| Thanks! Just tried rewiring that (w/o the resistors), and the LCD works the same way. It works fine, communicated directly with the PIC, but the 2nd panel (for which I'm trying to toggle the Enable) ... | |

Thanks, I guess I'll try again 
I am only grounding the pins I don't need (communicating with 4-bit data, doesn't use all the data pins.) //Cynthia |

Am I right in assuming that I can control several LCD panels from one pic, where they share all pins except the Enable pin? I am trying that, and then manually setting HIGH & LO ... |

Thanks again for all the help - it is finally working! I reworked all of the electronics onto a new breadboard, and that did it. No idea, really, what was going on, but now, I'm al ... |

| Well, I just soldered a different LCD Panel (same model, VK2220), to ensure no stray wires, etc, and I'm getting the same results. 1st line of black squares.
Any other thoughts? //Cynthia |

| Thanks, but that didn't work either. I tried inserting it, received a duplication error, and then realized it is already in the LCD.C code as #if defined(__PCH__)
