Problems with an initial start on an LCD library using MPLAB xc8...

Hi there

I am in the process of building an LCD library that I can use in other projects. The idea is to have most variables in a header file and all the functions in a C file. the problem is, it will not compile even when I strip out most of the functions. I don't understand why and I think it might have something to do with the #includes at the start of each file.

I am in the habit of over documenting my files as I do not program regularly enough to remember why I have done what I have done when I revisit the code in one or more years time.

All I have is an LCD initialisation function and it refuses to compile.

I have included all three files (the third is a test file once it has enough functions written to run it)

I am hoping someone might have a look and see (hopefully a rookie mistake) and let me know.

Kind Regards

Simon

It won't compile as you haven't finished the library..

You are using LCD Busy() and LCDCommand() and others, but you haven't written them!!!

Also to use __delay_ms() you need to define the crystal frequency.... # define _XTAL_FREQ '[frequency]'

"Also to use __delay_ms() you need to define the crystal frequency.... # define _XTAL_FREQ '[frequency]'"

What compiler error does this give Ian? If you don't use the #define

It will complain that __delay_ms() and __delay_us() are not defined...

i think we have one answer why LG's code isn't working ,
he has the #include but osc frequency defined. if i keep him off the laptop for the day, then i can look smart for 24 hours
