FREEMODBUS 1.1 MSP430 PORT
==========================
REQUIREMENTS
============
This demo application provides a port for the MSP430 series of processors
from Text Instruments. The port was done using the MSP430-P169 from
Olimex[1] which features a MSP430F169 MCU.
It requires a wired serial port to a host processor and a Modbus Master
Software on the PC side to be useful. Demo versions of Modbus Masters
can be found in [2] and [3].
INSTALLATION

TESTING
=======
Start the Modbus Sample Application and test if the input registers starting
at protocol address 1000 can be read. There are four registers value available
and the output should look like:
Polling slave (Ctrl-C to stop) ...
[1000]: 6474
[1001]: 0
[1002]: 0
[1003]: 0
Polling slave (Ctrl-C to stop) ...
[1000]: -8831
[1001]: 0
[1002]: 0
[1003]: 0
Polling slave (Ctrl-C to stop) ...
The simple testing utility used in the 'demo_rtu.bat' script can be found
at [4].
