Hmmm, had a look, but just to make sure: do you refer to the original topic about the arduino lcd extension with the ebay link?
Well, concerning the v3-lib, the type of code the guy wrote is really not my style and comments in German in an international used lib are imho completely clueless.
While comments describing an opcode and rather not what's the purpose of the code, aren't already pretty smart. LOL
I refer therefore to the lib with my mod, which was nothing else than twisting bits, it's name in my lib-directory here is: lcd_i2c.lib
Looking through arduino-docs, especially for LiquidCrystal_I2C.h/cpp, connections for the arduino-I2C-extension are made as follows:
Pcf P0 -> D4
Pcf P1 -> D5
Pcf P2 -> D6
Pcf P3 -> D7
Pcf P4 -> En
Pcf P5 -> R/W
Pcf P6 -> Rs
Pcf P7 -> Backlight
And that doesn't match your code.
