Hi all ,
I'm trying to make communicate an old game console (not very known but with some documentation) with a project using Arduino and I need to use Ethernet shield to send data to a web page. The game console use (it's what I think )a SPI interface but over only 3 wires (SKC,CS and one only line with SDI/O). I see in the documentation of Ethernet shield that i can not use the SPI (so neither the SPI.h library) because pins 10,11,12 and 13 are already in use by the ethernet controller. Additionally what is confuse for me is that there's only three wires . Well I don't know how to attack this . Do you think this is possible ? Some idea ? (I've never used yet an SPI interface) Thanks !
