LCD Address

Other Hardware Displays
1

Hello,
Pardon me for my format . This is my first post ever to ask for help concerning Arduino. I Will learn and improve.

I have tried the bperrybap, (hd44780) library to replace another.
The hd44780.h showed as it should.
#include <hd44780.h>

This is the library it replaced. It worked Reasonably well before.
#include<LiquidCrystal_I2C.h>

The actual replacement went well, except when compiling.

Farther down, for the LCD address,
LiquidCrystal_I2C lcd(0x27, 20, 4);
the error showed,

'LiquidCrystal_I2C' does not name a type.

Please, I do not understand this. Can you give me any suggestions to fix this ?

I suggest that you look at the example code that comes with the hd44780 library. A good start would be the "Hello World" example in the hd44780_I2Cexp class examples.

Got it done.

Thank you so much,
