'class LiquidCrystal_I2C' has no member named " "

[Thomas Rinaldi]

I've been trying to compile and load Focuserv255_DRV8825_HW203_F and seem to be having a problem with LiquidCrystal_I2C library. I've installed NewliquidCrystal library.

Focuserv255_DRV8825_HW203_M compiles and runs fine with App.

Any help would be greatly appreciated.

Hi Tom
Best start point is
1. make sure you are using Arduino IDE 1.6.8
2. delete any LCD libraries you maye have installed previously (in the documents\Arduino\libraries folder for windows)
3. Download the FM library
https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads/NewliquidCrystal_1.3.4.zip
4. Start Arduino IDE and use menu - Sketch - Include Library - Add .zip libray
5. Browse to where NewLiquidCrystal_1.3.4.zip is located, click on it to select it and then OK

Remember you might need to modify LCD statements - see attached PDF
using the I2cLCDguessor program - in next msg

then if you still have issues,
send me the .ino file that you made the changes to as per above
and
also the copy of the error messages in the Arduino IDE bottom window when you try to compile.

You need to first enable verbose output in the preferences before compiling. This will give a list of more detailed errors that helps pinpoint what libraries you are actually using and where the error is being generated.

Thanks for the help. I'll give that a try.

also do not forget to run i2cscanner to determine correct pot number of lcd chip

output is on arduino serial monitor at 9600

Again, thanks for the help. I was running the wrong version of the Arduino IDE. Once I installed v1.6.8 and added the libraries, it compiled and all is well.
