Calls to SPI.writeByte is not supported by native Arduino library

[Mega-mania]

Hi,

I have installed GUIslice to be used on an ATMega2560 with a Waveshare 4.0 Inch touch display. On compiling the code I found the ILI9486 library makes calls to the SPI library ( SPI.writeByte ) that are not supported by the native Arduino SPI library.

What should I do?

Arduino SPI library do not support function SPI.writeByte. You must use SPI.transfer instead.
You may apply attached patch (please remove .txt extension - Github does not accept patch files)
