I2C LCD

[midali]

To inilalize this display wyou need to write something like this

high RESET
pause 10
low RESET
pause 10
high RESET

I2CWRITE datapin, clockpin,$7C[$80,$57,$80,$6C,$80,$01,$80,$02]

before you can write to the display

I2CWRITE datapin, clockpin,$7C[$80,$80,$40,$48,$45,$$4C,$4c,$4F]  'HELLO

I do not have a display to test so not sure if this will work, but this is what I would start with, I took the code from the data sheet.

Thx Dave, I tried but nothing!
I tried a code for 7036i controller, with V0 connected to Vdd , but I feel that somewhere I'm wrong in DEFINE LCD .
I know that your help eat a lot of time, but if somebody have a free time to read in datasheet and help me, I'll appreciate!
