Using The Prototyping Board - RabbitCore RCM4500W User Manual

B.4 Using the Prototyping Board
The Prototyping Board is actually both a demonstration board and a prototyping board. As a dem-
onstration board, it can be used to demonstrate the functionality of the RCM4510W right out of
the box without any modifications to either board.
The Prototyping Board comes with the basic components necessary to demonstrate the operation
of the RCM4510W. Two LEDs (DS2 and DS3) are connected to PB2 and PB3, and two switches
(S2 and S3) are connected to PB4 and PB5 to demonstrate the interface to the Rabbit 4000 micro-
processor. Reset switch S1 is the hardware reset for the RCM4510W.
The Prototyping Board provides the user with RCM4510W connection points brought out conve-
niently to labeled points at header J2 on the Prototyping Board. Although header J2 is unstuffed, a
2 × 25 header is included in the bag of parts. RS-232 signals (Serial Ports C and D) are available
on header J4. A header strip at J4 allows you to connect a ribbon cable, and a ribbon cable to DB9
connector is included with the Development Kit. The pinouts for these locations are shown in
Figure B-4.
Although analog signals are shown for labeled points at header location J3 on the Prototyping
Board, the analog signals on the RCM4510W are associated with the XBee RF module. These
analog signals are not brought out to the Prototyping Board.
