Hi:
I got a few questions on this Eval Board (EVB):
(1) Can I write some C program into uM on this EVB? If it's possible, how?
(2) How do I connect any servos to this EVB?

Thank you for the help.

David

texram,
I'm still waiting for my board but if you want to connect the servos they plug into the flyleads that you can see here:
http://www.sparkfun.com/commerce/produc ... cts_id=707
The leads are at the far end. Two are sockets for the elevator and rudder channels and three of the leads are plugs to go direct to your radio receiver. The "extra" plug was connected to the throttle channel in the prototype airplane.

There is a free, student edition, C compiler available at microchip.com (exact site depends on your location) which will work with the MPLAB IDE from the same people.

I presume that you know that you link your C code with the IDE's assembler; and use an ICD 2 to load the code into the board's processor.
My ICD 2 is on it's way from:

I hope this helps,

That ICD 2 looks suspiciously similar to a PICkit 2, part from the lettering. Are you sure that it really is an ICD 2?

Leon,
I see what you mean. It certainly looks similar to a PICkit 2, but the case is probably used everywhere. It is clearly labeled Mini ICD 2 in the photo on Ebay. The item is also described as an ICD 2 in the text.
I considered Sparkfun's Tiny ICD 2, but that only has RS232 and I wanted USB.
What is the difference between a PICkit 2 and ICD 2? I went for the latter because that's what Sparkfun said that I would need. Both say they do in circuit programming/debugging with my PIC and they both connect to the PC and PIC in similar ways.

regards,

Scouser
