B.4 Using the Prototyping Board
The Prototyping Board is actually both a demonstration board and a prototyping board. As
a demonstration board, it can be used to demonstrate the functionality of the RCM4100
series of modules 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 RCM4100. 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 microprocessor. Reset switch S1 is the hardware reset for the RCM4100.
The Prototyping Board provides the user with RCM4100 connection points brought out con-
veniently 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.
Figure B-4. Prototyping Board Pinout
The analog signals are brought out to labeled points at header location J3 on the Prototyping
Board. Although header J3 is unstuffed, a 2 × 7 header can be added. Note that analog
signals are only available from the RCM4100 — the RCM4110 and RCM4120 models do
not have an A/D converter.
