I notice that the new DeviceOpen function only delivers information from the original first 13 digital pins and 2 analog pins. Is there a practical sketch that allows to take advantage of all the pins offered by the other Arduino devices?. For example the Mega 2560. Need to read several analog readings. Please advice.
UPDATE What area is to be study to allow me design my own driver to connect other device as such as the MEGA 2650 to Wolfram Mathematica?
