Hello everyone! First time posting, though I have been on this site countless times - you guys do some amazing things here! So, I am trying to do something similar to that 3DS controller mod by loopy or dekuNukem (http://3dscapture.com/forum/viewtopic.php?f=6&t=2169 and https://docs.google.com/document/d/1-dCfkwnoIebxSwfW9gZ9NFpktMHbVTEVkIrduLGLTMM/edit respectively). Instead of trying to control the device with a gamecube controller, I want to control it with a micro controller (using an Arduino Uno right now). Basically a simple macro maker - you read in input and then write it back at a later time. Everything was going well until I got to the analog stick! I noticed in dekuNukem's mod, you have to disconnect the the slider pad and switch between which one you are using. This is what I was originally going to do. I noticed that when I have the analog stick and my arduino both sending signals to the analog stick, they don't seem right; writing the value that I previously read in wasn't working, I assume because the analog stick was still connected and still giving voltage. But then I saw the loopy mod, which doesn't touch the slider pad! I asked him about it and he said that he used "IDACs (current DAC)". I have been using a digital potentiometer to get an analog signal in there, but was going to get a DAC (digital to analog converter) anyway since they just seem more flexible. So, the question really is, does anyone know how to basically get two analog sticks (one being a micro controller in my case) connected together and be able to work together like the loopy mod? Note: I am actually doing all my testing on a gamecube controller since I can afford to fry some of those in my testing. I assume that the analog sticks are the same or at least very similar, but we all know what happens when you assume things... Any info would be awesome! My electronic skills are lacking to say the least, so finding a solution has been very difficult with my limited knowledge. Thanks for reading!
