I am new to Arduino and "C++".. (also to this forum)
I am looking for the same answers for using the I2C (4wire) LCD display...
My frustration level (H)....................L
I am running IDE 1.0.5-r2 on both XP and Linux Kubuntu...
I have a "clone" of an Arduino uno Mega328
I have an I2C to LCD board with the address of 0x27 (confirmed with the I2C scanner program and the Serial Monitor)
I can load a Sketch into the uno (like blink) and it will run (also the I2C scanner works) BUT most of the examples I have downloaded and attempted to run fail with compiling errors identical to sansai's attempts...
I have also tried different LiquidCrystal versions
(LiquidCrystal_I2C.h),
(TWILiquidCrystal.h) all moved into a clean LiquidCrystal folder.
I have programed Parallax Basic Stamps with few problems over the years and wanted to try my hand at C++ language and make my Uno perform some timed lighting controls with a RTC, Keypad, and a serial (I2C) LCD display...
I am wondering "if" the version of the IDE I'm attempting to run has some changes that the syntax that may be in need of some changes that I'm not aware of... I spent a couple of days with the clone not taking sketches only to find out the USB cable supplied was very intermittent... I can now talk to the Uno I just can't get any LCD sketches to compile...
The hardware seams to be working OK...I'm lost between being new at this hardware and software and don't really know what is causing my pains.... Also are ALL the Library names supposed to change to brown (like wire.h) indicating the sketch has found the files?
How about throwing some peanuts to this helpless monkey?
