Hi, Bill:Thanks again.Here is the datasheet I used to do the wiring http://fritzing.org/projects/128x64-lcd/
I also read the the ks0108mega.h file #define glcdDI 36 // D/I Bit // Reset Bit - uncomment the next line if reset is connected to an output pin #define glcdRES 30 // Reset Bitit seems the only difference for the datasheet I used and those states at the config file is those I copied above, is there a difference of D/I bit and RS. My reset is 17 not 30, should I use 30 instead.
When I compile the sketch, do I need to disconnect the reset, let the sketch upload and connect the reset.
I have used the GLCDdiags and nothing happen to the LCD display. you mentioned about using the diag and until it pass, is this diag the same as the GLCDdiags sketch I used.
When I compiled the GLCDdiags, other than the comment regarding the byte,
there is no other information. You also said diag reports information out the serial port, where can I find the serial port, bear with me, I know it sounds kind of stupid.
BTW, I tried to open the Mega.h file but I cannot open it from my file directory, i.e. users/xxxxx/Document, how can I modify the .h file. I know probably in the future I need to uncomment the reset or change the file.
