Open the Propeller Tool and type in the following program:
CON
PUB LedOnOff
Click on File and save the program as “ConstantBlinkRate.” Switch on your Protoboard and
press F11 to send the program to your Propeller. The LED should be flashing on and off.
Experiment with the waitcnt(clkfreq/2 + cnt) lines by changing the 2 to another number.
The program starts by setting the speed the Propeller should run with the two lines in the CON
section. Dira[23]:=1 sets Propeller P23 as an output. The outa[23]:=1 and 0 turn the LED on
and off.
The Protoboard has access to all 32 of the Propeller’s I/O (input/output) pins. They can be
accessed easily from the holes that surround the Propeller CPU at the center of the board.
