The Demo Program
The F5132EX board is factory programmed with a simple demo program. To use the demo: leave
the jumpers in their factory setting, connect the board to a PC serial port using the cable included, start
up a terminal program on the PC (Hyperterm or Tera Term, for example) set the port for 9600 bps, 1 stop,
no parity, HW control off. Connect the F5132EX to a DC power supply or battery using connector W1.
You will see the banner on the PC:
***********************************
* EA Electronics *
* MSP430F5132 Demo Program V1.0 *
***********************************
If you type a line in lower case on the terminal program, the demo program echoes back the line
in upper case after you hit the enter key. So if you type:
now hear this.
Followed by the enter key, the program echoes back :
NOW HEAR THIS.
The program also configures all port pins (except P1.1 & P1.2) as outputs and toggles them twice
a second.
