Hi All, I am very new to arduino. So far I have managed to hook up an accelerometer and get it running with the values appearing in the monitor. I then went and bought a display made by DF Robot.
I went and got the particular library and was able to compile the sketch example for the parallel method of operating. 
So far so good.
I also got the sketch example to run the display in serial [it can do both serial and parallel mode]. This is when I got compile errors.
Here is a list of the errors I got. I have no idea what to do now and hope someone can help me.

Note: I have also copied the example sketch at the bottom of this message in case this can be of use. And further down the header file and .cpp file.
