RabbitCore RCM3200
SWITCHCHAR.C
—This program demonstrates transmitting and then receiving an
ASCII string on Serial Ports B and C. It also displays the serial data received from both
ports in the STDIO window.
To set up the Prototyping Board, you will need to tie TxB and RxC
together on the RS-232 header at J5, and you will also tie RxB and
TxC together using the jumpers supplied in the Development Kit as
shown in the diagram.
Once you have compiled and run this program, press and release S2
and S3 on the Prototyping Board. The data sent between the serial ports will be dis-
played in the STDIO window.
Two sample programs,
SIMPLE485MASTER.C
and
SIMPLE485SLAVE.C
, are available to
illustrate RS-485 master/slave com-
munication. To run these sample pro-
grams, you will need a second Rabbit-
based system with RS-485, and you
will also have to add an RS-485 trans-
ceiver such as the SP483E and bias
resistors to the RCM30/31/32XX
Prototyping Board.
The diagram shows the connections. You will have to connect PC0 and PC1 (Serial Port D)
on the RCM30/31/32XX Prototyping Board to the RS-485 transceiver, and you will con-
nect PD4 to the RS-485 transceiver to enable or disable the RS-485 transmitter.
The RS-485 connections between the slave and master devices are as follows.
RS485+ to RS485+
RS485– to RS485–
GND to GND
SIMPLE485MASTER.C
—This program demonstrates a simple RS-485 transmission of
lower case letters to a slave RCM3200. The slave will send back converted upper case
letters back to the master RCM3200 and display them in the STDIO window. Use
SIMPLE485SLAVE.C
to program the slave RCM3200.
SIMPLE485SLAVE.C
—This program demonstrates a simple RS-485 transmission of
lower case letters to a master RCM3200. The slave will send back converted upper case
letters back to the master RCM3200 and display them in the STDIO window. Use
SIMPLE485MASTER.C
to program the master RCM3200.
3.2.2 Other Sample Programs
Section 6.5 describes the TCP/IP sample programs, and Appendix C.8 provides sample
programs for the optional LCD/keypad module that can be installed on the Prototyping
Board.
