IOCONFIG_SWITCHECHO.C
—This program demonstrates how to set up Serial Port F,
which then transmits or receives an ASCII string to/from Serial Port D when switch S2
or S3 is pressed. The echoed serial data are displayed in the Dynamic C STDIO window.
Note that the I/O lines that carry the Serial Port F signals are not the Rabbit 4000
defaults. The Serial Port F I/O lines are configured by calling the library function ser-
Fconfig()
that was generated by the Rabbit 4000 IOCONFIG.EXE utility program.
Serial Port F is configured to use Parallel Port C bits PC2 and PC3. These signals are
available on the Prototyping Board's RS-232 connector (header J4).
Serial Port D is left in its default configuration, using Parallel Port C bits PC0 and PC1.
These signals are available on the Prototyping Board's RS-232 connector (header J4).
Also note that there is one library generated by IOCONFIG.EXE in the Dynamic C
SAMPLES\RCM4000\SERIAL
folder for the 58 MHz RCM4100 and RCM4010.
To set up the Prototyping Board, you will need to tie TxD and RxC
together and tie TxC and RxD together on the RS-232 header at J4
using the jumpers supplied in the Development Kit. (Remember that
RxC and TxC now are actually RxF and TxF.)
Once you have compiled and run this program, press and release
switches S2 or S3 on the Prototyping Board. The data echoed between the serial ports
will be displayed in the STDIO window.
