Hello
Has anyone built this unique flip clock using a 2.2 inch color graphics display found at this website:
http://olganet.com/electro/2014/03/17/h … 2-240x320/
The host has done a nice job of posting the schematic and main code but does not say where we can get the specific include libraries he used.
The problem is; Im having trouble getting his code to compile.
I think the problem is with 2 of the libraries that I obtained from the Arduino github repository.
Im afraid that I don’t know enough about Arduino C to get the RTClib and Button libraries working.
/**

#include <SPI.h> //working
#include “Adafruit_GFX.h” //working
#include “Adafruit_ILI9340.h” //working
#include <Wire.h> //working
#include <RTClib.h> // This library is giving me grief…
#include <Button.h> // This library is giving me grief…
Expenditure:
I purchased all the parts for the project from Ebay. total cost so far $26.00
I have spent 18hrs trying different things.
Im using the latest Arduino IDE 105r2 I have tried many other versions.
I haven’t posted the errors reported by the Arduino IDE as they are numerous and obscure
I hope someone can shed some light on this project or tell me if I should just give up.
Thanks too all.
