FT-817 External Display

Hi,I’m wondering if anyone has a idea or the code so I can make this sketch work,it asks for a I2C display and all I have is a HD44780 20x4 on a freetronics stepduino
The project is called Arduino FT817 Master

Thanx

FT817.cpp (13.7 KB)

Can't open a .cpp file with arduino.

Try the LiquidCrystal Library - Hello World example sketch. I don't think you have an I2C display.

Hello All, I checked the sketch for any indication of what it does, but can't figure it out. I am trying to get an external LCD display to work for it, since the FT817 has a very small display and can use a lot of help. Has successfully done this? if this is not the sketch for that does anyone know where I can find some help with my project? I have a Duemilenove and an UNO rev.3, I can easily get any other components as needed. Thanks in advance. KG7CPB, 73.
