EDIT
You must use the MCC18 complier c2.4. Later versions will NOT work.
The following instructions assume you have access to either and EasyC install, activated or trial.
If you can find a copy of the MCC18 v2.4 installer you can skip copying the folder from EasyC.
/EDIT
If you have a copy of EasyC installed you'll find the folder "c:\program files\Intelitek\EasyC\mcc18" (this may not be quite right, but its close). This folder contains the MCC18 complier and other required files. Copy that folder to "C:\mcc18".
Then install MPLAB IDE from
http://www.microchip.com/stellent/id...&part=SW007002.
You can find the default source code and documentation at
http://www.ifirobotics.com/rc.shtml#Programming. IFI loader, which is used to transfer the program to the robot can also be found on that page.
This information is all from memory. I haven't had to work with the IFI system for some time, so there may be small errors in this post.
