Here is what I see happening:
- User plugs in adapter to the "universal" plug on the netduino.
- Some sort of chip identifies the connector being adapted; used to show corresponding image and pinout
- A probe is used to touch the other end of the tested cable, which could be a different connector or loose wire
- The display shows in big numbers the pin being touched and a graphical representation
- User types in on a keypad what pin they want to activate. Signal sent to that pin.
- User probes the other end of the tested cable
- When the line is found the netduino buzzer beeps and screen flashes maybe
This will be my first project with the netduino and programming at large. I was hoping someone could give me some initial guidance in these areas:
- Can someone recommend some compatible hardware that is easy to use and will work with the board? I'm poor so my budget is an issue, I don't want to go buying parts I can't use
- Is a touch screen with an alphanumeric input that much harder to program? I realized after I drew my pictures a lot of connectors use a mix of ABC and/or 123 so I'd like to keep that consistent in the display.
- How would I test a connector that has 70+ pins if the netduino only has limited ports?
- In this example I drew a "chip" that would alleviate the need to manually enter what type of adapter cable you plugged in every time. Is there an electronics part out there that can serve as a unique identifier that doesn't take, like, EPROM programming? I could likely program a large bank of netduino_pin_1 <---> connector_a_pin_1 tables, but I'm thinking that chip would be the easiest way of selecting the table for connector_a. Maybe a DIP switch somewhere?
Thanks for any help or suggestions. I plan on getting started on this as soon as my parts arrive.
