There are two version of the EDU controller. One is based around a BASIC stamp, has an internal radio modem and requires an OI. The current version of the EDU is based off of a PIC, programmed in C and does not need an OI. It can operate completely on its own.

Could you set the FRC into autonumous mode so that it wouldn't need the OI?
|
Even in auton mode, the old (PBASIC) RCs need an oi.
There is really no(practical) way i can think of to get around needing an OI on the old style FRC.

What would it take to get the FRC to interface with the Dashboard port? How would you get the EDU-BOT RC to interface with the Dashboard port?

In both cases, you need to build a serial crossover cable. By this i mean a cable with the transmit pin of one end of the cable connected to the receive pin of the other end and vice versa. Occasionally i have seen these on sale in computer stores labeled "null modem cables". I have also sometimes seen null modem adapters which you affix to one end of a normal serial cable. you can easily take a standard serial cable and reverse the two wires. Besides ground, the only two wires that are used in our case are receive and transmit.

Is there any way of getting the Digital Inputs to become outputs on the FRC (I mean, they are just I/O pins on the chip, right?) I'm up for anything at this point, so any help would be greatly appreciated.

Not so easily. The inputs are actually connected to another microcontroller called the "master processor" You have no control over this chip. The master proc communicates what it seas on these inputs through another serial link inside the controller to the "user processor" (the one you program).
On the new EDU controller as well as the new (2004 and up) full size RC, the IO pins are directly connected to the user processor and can be used however you want to use them.
If you do not have a new style EDU, you could use a new(2004 and up) full size RC. Without an OI, you will get scary error lights but the user processor will still function and have access to the serial port and IO ports. Thats all you need. You will have to program it in C.
To sum things up, if you want to get around needing an RC and need digital output, you need to use either a new style EDU or a new style full size controller.
