Anyone know where i can find an up to date Command list for this Serial Backpack ?

The datasheet on Sparkfun is incorrect.

I cannot link the datasheet as this is my first post but there was another inquiry for this and no help :S

Any help would be appreciated...

Have you tried emailing the author of this tutorial? Or Sparkfun support in general?

This appears to be the correct link to the source code...

http://www.sparkfun.com/Code/Graphic%20LCD%20Backpack%20-%20ATMega168.zip

In the worst case, you can get to it from here...

;D

Ok, for all the noobs like myself out there... to place cursor :

Serial.print(0x7C, BYTE); // command follow
Serial.print(0x19, BYTE); // X-axis follows
Serial.print(0x00 BYTE); // 00 is X-axis in HEX

Serial.print(0x7C, BYTE); // command follow
Serial.print(0x18, BYTE); // Y-axis follows
Serial.print(0x00, BYTE); // 00 is Y-axis in HEX

this seem to be right and all the other info on the Datasheet.

Now... :-/ anyone knows what the command is for setting the Contrast ? (Brightness/Backlight is 0x7C 0x02)

Again any help would be appreciated.

Thanks
