SIMPLE3WIRE.C
communication. Lower case characters are sent by TxC, and are
received by RxD. The characters are converted to upper case and are
sent out by TxD, are received by RxC, and are displayed in the
Dynamic C
To set up the Prototyping Board, you will need to tie TxD and RxC together on the
RS-232 header at J2, and you will also tie RxD and TxC together using the 0.1" jump-
ers supplied in the Development Kit as shown in the diagram.
SIMPLE5WIRE.C
with flow control on Serial Port C and data flow on Serial Port D.
To set up the Prototyping Board, you will need to tie TxD and RxD
together on the RS-232 header at J2, and you will also tie TxC and
RxC together using the 0.1" jumpers supplied in the Development Kit
as shown in the diagram.
Once you have compiled and run this program, you can test flow con-
trol by disconnecting TxC from RxC while the program is running. Characters will no
longer appear in the
back to RxC.
SWITCHCHAR.C
ASCII string on Serial Ports C and E. It also displays the serial data received from both
ports in the
Before running this sample program, check to make sure that Serial
Port E is set up as an RS-232 serial port—pins 1–3 and pins 2–4 on
header JP2 on the Prototyping Board must be jumpered together using
the 2 mm jumpers supplied in the Development Kit. Then connect TxC
to RxE and connect RxC to TxE on the RS-232 header at J2 using the
0.1" jumpers supplied in the Development Kit as shown in the diagram.
SIMPLE485MASTER.C
lower case letters to a slave RCM3750. The slave will send back converted upper case
letters back to the master RCM3750 and display them in the
SIMPLE485SLAVE.C
Serial Port E is set up as an RS-485 serial port—pins 3–5 and pins 4–6 on header JP2
must be jumpered together using the 2 mm jumpers supplied in the Development Kit.
SIMPLE485SLAVE.C
transmission of lower case letters to a master RCM3750. The slave
will send back converted upper case letters back to the master
RCM3750 and display them in the
SIMPLE485MASTER.C
Serial Port E is set up as an RS-485 serial port—pins 3–5 and pins 4–6 on header JP2
must be jumpered together using the 2 mm jumpers supplied in the Development Kit.
