3.2.2 Serial Communication
The following sample programs are found in the SAMPLES\RCM4200\SERIAL folder.
FLOWCONTROL.C
—This program demonstrates how to configure Serial Port D for
CTS/RTS flow control with serial data coming from Serial Port C (TxC) at 115,200 bps.
The serial data received are displayed in the STDIO window.
To set up the Prototyping Board, you will need to tie TxD and RxD
together on the RS-232 header at J4, and you will also tie TxC and
RxC together using the jumpers supplied in the Development Kit as
shown in the diagram.
A repeating triangular pattern should print out in the STDIO window.
The program will periodically switch flow control on or off to demonstrate the effect of
flow control.
If you have two Prototyping Boards with modules, run this sample program on the
sending board, then disconnect the programming cable and reset the sending board so
that the module is operating in the Run mode. Connect TxC, TxD, and GND on the
sending board to RxC, RxD, and GND on the other board, then, with the programming
cable attached to the other module, run the sample program.
PARITY.C
—This program demonstrates the use of parity modes by
repeatedly sending byte values 0–127 from Serial Port C to Serial Port D.
The program will switch between generating parity or not on Serial
Port C. Serial Port D 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 TxC and RxD together on the
RS-232 header at J4 using one of the jumpers supplied in the Development Kit as
shown in the diagram.
The Dynamic C STDIO window will display the error sequence.
SERDMA.C
—This program demonstrates using DMA to transfer data from a circular
buffer to the serial port and vice versa. The Dynamic C STDIO window is used to view or
clear the buffer.
Before you compile and run the sample program, you
will need to connect the RS-232 header at J4 to your PC
as shown in the diagram using the serial to DB9 cable
supplied in the Development Kit.
Once you have compiled and run the sample program,
start Tera Term or another terminal emulation program
to connect to the selected PC serial port at a baud rate of
115,200 bps. You can observe the output in the Dynamic C
STDIO window as you type in Tera Term, and you can
also use the Dynamic C STDIO window to clear the
buffer.
The Tera Term utility can be downloaded from
