Hello,

Please see this product:

This board allows you to enrich your device with 128x64px graphical display or LCD 2x16 or 4x20 character display using 4-wire SPI interface

Serial LCD/GLCD Adapter Board
http://www.mikroe.com/add-on-boards/dis ... d-adapter/



You need uC with two SPI ports.


Best regards,
Peter

Hello,

I have not tested this but I have to admit that it is interesting. I will certainly make a test.

SPI Graphic Lcd Library
http://www.mikroe.com/download/eng/docu ... ibrary.htm

or

One GLCD can go over SPI and one on standard way. But we need few pins more.

Hello,

Please see code example for two GLCD 128x64 with PIC18F45K22.
One GLCD is connected on EasyPICv7 GLCD socket and second is connected over Serial LCD/GLCD display adapter using SPI on PortC :

Hello,

Two SPI ports is possible but requires changes.

For now use the solution described earlier.

Also if you want to use SPI2 port with PIC18F45K22 EasyPICv7 and LCD/GLCD Adapter (HW Ver 1.02) you need to make some changes in connections.


Best regards,
Peter
