1.0 updated to work with my philips LCD shield #5

Closed eagle00789 closed 11 years ago

eagle00789 commented 12 years ago

The 1.0 version posted here doesn't work my lcd shield.

Below is the code to make it work: colorlcdshield.h

/*
  ColorLCDShield.h - Arduino Library to control a Nokia 6100 LCD, 
  specifically that found on SparkFun's Color LCD Shield.
  This code should work for both Epson and Phillips display drivers 
  normally found on the Color LCD Shield.

i don't use that much git and to fork it and stuff takes to much time....

stevesparks commented 11 years ago

What was your actual change? We merged in some Philips changes today, maybe its better now...

ToniCorinne commented 11 years ago

Closing this issue due to a lack of response from OP.
