3.1.3 Serial Communication
The following sample programs can be found in the
Two sample programs,
CONTROL.C
are available to illustrate RS-232
communication. To run these sample
programs, you will have to add an
RS-232 transceiver such as the
MAX232 at location U2 and four
100 nF charge-storage capacitors at
C3–C6 on the Prototyping Board.
Also install the 2 × 5 IDC header
included with the Prototyping Board
accessory parts at J6 to interface the
RS-232 signals.
The diagram shows the connections.

CORE_FLOWCONTROL.C
program demonstrates hardware flow control by configuring Serial Port C (PC3/PC2)
for CTS/RTS with serial data coming from TxB at 115,200 bps. One character at a time
is received and is displayed in the
To set up the Prototyping Board, you will need to tie PC4 and PC5
(TxB and RxB) together at header J4, and you will also tie PC2 and
PC3 (TxC and RxC) together as shown in the diagram.
A repeating triangular pattern should print out in the
The program will periodically switch flow control on or off to demon-
strate the effect of no flow control.
Refer to the
ence Manual for a general description on how to set up flow control lines.
CORE_PARITY.C
sending byte values 0–127 from Serial Port B to Serial Port C. The program will switch
between generating parity or not on Serial Port B. Serial Port C will always be checking
parity, so parity errors should occur during every other sequence.
To set up the Prototyping Board, you will need to tie PC4 and PC3
(TxB and RxC) together at header J4 as shown in the diagram.
