I have a cheap wireless controller which drives the bus with 5 volts! Nothing seems Who knows if this could damage the console port? (In fact, Internal pullup or sending a 1 in output mode must not be done since this would Otherwise, I configure it as input-no_pullup.Ěctivating the I acheive this by playing with the Atmega8 pin direction. To 0, it just has to pull the signal to ground. When someone (gamecube or controller) wishes to set the signal On the gamecube side, the data signal is held at 3.43 volts via a pullup resistor If I had powered the MCU with only 3.3 volts, I would have had to useĪn ATmega8L which cannot run at clock rates above 8 mhz.Would have been necessary to use a voltage divider which would have required To preventĮxposing the microcontroller input to voltages higher than it's own, it The data signal from the controller is at 5 volts when high.I cannot know for sure what is the voltage threshold for a logic 1.
(As I dont have the official controller specifications, It's better to use 5 volts for a logic 1 when driving the controller'sĬLock and Latch pins.
Later, since a friend kept insisting that I should also design a N64 to Gamecube/Wiiīecause of the complexity of the Gamecube's controller protocol, it's not possible to build a I started by doing the NES and SNESĪdapter. Testing my code which I had prepared in advance. To continue enjoying the classics with proper controllers.Īs soon as I got access to a Wii (I still dont have mine), I started Update!: Since the Wii U and new Wii models are built without gamecube ports, I haveĬreated a new project that works via the Wiimote, making it possible Thinking about designing an Snes/Nes controllers to Gamecube adapter which would It would be possible to use Gamecube controllers to play those games, I started
The Wii, is in my opinion one of their greatest ideas. Nintendo's idea of implementing support for NES, SNES and N64 games in their new console,
