I need help with switching signals

Former Member

Hi there

Although I know a thing or two (ok, maybe 1.5 things) about soldering, I am fairly new to this electronics thing. I've been thinking about starting a secret project that I will only share once I finish. I had trouble finding the materials I need such as the battery, the charging mechanism, ...etc. That is not important right now. As I was listing down the things I wanted it to do, I encountered something I don't know how to solve, thus I need your guys' help

Say I'm connecting two points together (let's call them A and B). Now, I need to switch the output from B to another point called D that gets it's signal from point C by pressing a button. Basically I want to flip the signals (you can think of it as cross multiply in math terms) Now you could say "just use a slide switch, you dummy" but the problem is I have 60 inputs and outputs. do you think you can help me with this?

I thought of using an EEPROM because they have a lot of pins so that I would only need to use 2 of them, but I know nothing on how to program them. I would assume a micro controller would be better but I don't know how to program it either, and I assume it's not as cheap as an EEPROM. I also have no experience in using an arduino. I do, however, know the basics of java, so if that helps please tell me

I really wanna do this. I've been thinking about it for quite a while. Please help.

    honestly, I don't know. As I explained, I am not that good with electronics. I figured that all signals would all be the same since they're (according to my understanding) just a series of binary numbers. I can provide you with the names of the pins, if that helps

     

    Basically, what happens with a cartridge based console, is the console powers up the cartridge with (in the case of the Nintendo Entertainment System aka NES) 5V, and then the cartridge sends signals from two EEPROMs on it to the console.

    You still haven't explained what you want to do !

     

    If it's 5V logic (and it could be because the NES is such old technology) then you can forget about FPGA's because they won't work with 5V.

     

    Are you trying to select between two different cartridges -  if so it may well not be necessary to switch all the signals but just make sure that only one cartridge is enabled at a time.

     

    If you can explain what you are trying to make or do it may be possible to help.
