Software

To use the AS1115 RGB Demoboard a controller is required. The controller can be connected to the demoboard via the I/O Connector “D” .

If no controller is available the austriamicrosystems USB box in combination with the AS1115 RGB Demoboard software can be used as well. This USB box is needed to set-up the connection between the demoboard and the

USB interface of a PC. The USB box can be ordered via http://www.austriamicrosystems.com

.

To get the AS1115 RGB Demoboard running set the Interface to I²C and the Nr. of Chips to 3. The black drawn boxes represent the single RGB-LEDs and the gray small boxes represent one color of the RGB-LEDs. Click them to turn the LED on.
