Propeller Example – TSL230 Simple Demo.spin
This example reads the frequency output on pin 6 and displays the number on a television, and it makes
use of the TV_Text object that is included in the home folder of the Propeller Tool software. (If you are
not using a Propeller Demo Board, see its schematic for information on connecting a TV to the Propeller
chip.) Pins 1 and 2 of the TSL230R are connected to two consecutive pins on the Propeller and set the
sensitivity of the TSL230R. For this example the pins are explicitly set to the middle range x10. These can
be set to any sensitivity required for the application.

Build the circuit shown above, connecting to the BS2 I/O pins as shown.
Enter and run TSL230R-Test.bs2, listed below.
Pass a flashlight over the TSL320R; you should see the value in the Debug Terminal rise as the
TSL230R receives brighter light.
