    Question

    I do not know if any issue ...

    But found this on Melab's site:

    LAB X1
    Compatible with the following microcontrollers:

    PIC16C64(A), 16C65(B), 16C662, 16C67, 16C74(AB), 16C765, 16C77, 16C774, 16F74, 16F747, 16F77, 16F777, 16F871, 16F874, 16F874A, 16F877, 16F877A, 16F884, 16F887, 16F914, 16F917, 18C442, 18C452, 18F4220, 18F4221, 18F4320, 18F4321, 18F4331, 18F4410, 18F442, 18F4420, 18F4423, 18F4431, 18F4439, 18F4450, 18F4455, 18F4458, 18F448, 18F4480, 18F4510, 18F4515, 18F452, 18F4520, 18F4523, 18F4525, 18F4539, 18F4550, 18F4553, 18F458, 18F4580, 18F4585, 18F4610, 18F4620, 18F4680, 18F4682, 18F4685

    I don't think he's using the LAB X1, just the code has that in the comments.

    Very possible...but, it works correctly (I think, haven't really determined that) and the LCD only messes up after running for a second or so.

    Hi Fredrick,
    I had an issue with some "Import" LCD units and I solved it with a bypass capacitor on the power and ground leads, Pin 1, 2 . My issue was similar to yours.
