Two sample programs, SIMPLE485MASTER.C and SIMPLE485SLAVE.C, are available
to illustrate RS-485 master/slave communication. To run these sample programs, you will
need a second Rabbit-based system with RS-485—the second system may be another
RCM3900, or it may be any Rabbit single-board computer or RabbitCore module that sup-
ports RS-485 serial communication as long as you use the master or slave sample program
associated with that board.
Before running either of these sample programs on the RCM3900 assembly, make sure
pins 1–2 and pins 5–6 are jumpered together on header JP5 to use the RS-485 bias and ter-
mination resistors. The sample programs use Serial Port C as the RS-485 serial port, and
they use PD7 to enable/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. The slave will send back converted upper case letters back
to the master and display them in the STDIO window. Use SIMPLE485SLAVE.C to
program the slave—reset the slave before you run SIMPLE485MASTER.C on the
master.
SIMPLE485SLAVE.C
—This program demonstrates a simple RS-485 transmission of
lower case letters to a master. The slave will send back converted upper case letters
back to the master and display them in the STDIO window. Compile and run this pro-
gram on the slave before you use SIMPLE485MASTER.C to program the master.
3.2.4 Real-Time Clock
If you plan to use the real-time clock functionality in your application, you will need to set
the real-time clock. Set the real-time clock using the Dynamic C SAMPLES\RTCLOCK\
SETRTCKB.C
sample program by following the onscreen prompts. The Dynamic C
SAMPLES\RTCLOCK\RTC_TEST.C
sample program provides additional examples of
how to read and set the real-time clock.
3.2.5 Other Sample Programs
Section 6.6 describes the TCP/IP sample programs, and Appendix C.7 provides sample
programs for the optional LCD/keypad module that can be installed on the Prototyping
Board.
