GLCD Problem

[JohnCrow]

Hi
Ive just received a glcd e-bloclk, but it seems totally dead.
Ive tried it using your test program and the display just stays dark

Tested using 2 different EB006 programmers and different 16F877As

The S/M led on the top right is not lit, and the board is drawing 18uA from the programmer (Connected to the 14V output as per section 2 page 5 of the data sheet,measured 12.48V on the power terminals of the glcd board)

The display board is pressed fully down on the main board sockets
Any ideas?
Thanks

Hello John,

I think the problem is the released component code file for this display is slightly incorrect. Here is an up to date version which should work a lot better for you.

PIC_gLCD.c

(44.52 KiB) Downloaded 382 times

Simply copy the file into your Flowcode v4/Components directory before starting Flowcode.

In the component connections window only the chip select pin is used by the gLCD when in EB057 mode. The other pins used are the hardware SPI pins.

Let me know if your still having problems and I'll see what I can do to get you up and running.
