I'm creating a new library to control the keypad and LCD together. Most of the code seems to compile, but when it reaches the line where I define the LiquidCristal variable, it says:
'LiquidCrystal' does not name a type when creating a custom library
This is the extract of content of my LCDKeypad.h
// Include types & constants of Wiring core API
#if defined(ARDUINO) && ARDUINO >= 100
#include "Arduino.h"
#else
#include "WProgram.h"
#include "WConstants.h"
#endif
// Include LCD library
#include <LiquidCrystal.h>
The error is in this line:
private:
LiquidCrystal lcd( 8, 9, 4, 5, 6, 7 ); // <<-- Error
