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 AS1116 Bicolor 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 realize a panel with more than 64 LEDs, it’s possible to connect more AS1116 demoboards. Connect the SDO pin of one AS1116 to the SDI pin of the next AS1116.The SCL and LD pin have to be connected in parallel. With the austriamicrosystems Demosoftware it’s possible to connect up to 4 devices. Take care to set the ‘Nr. Of Chips’ accordingly in the software. To draw a picture, click the left or right small box to put one of the two colors of the dual LED’s on. Of course it’s also possible to activate both channels at the same time to get the mixture of both colors. Operational sequence This demo board comes with two AS1116. 1. Drive the IC on the demo board only with the recommended settings and values as described in the datasheet. If not present get the datasheet for the AS1116 from www.austriamicrtosystem.com. 2. First connect the power supply via connector “C” to a powered USB port and than power up the I/O Interface “D”. To power down the system disconnect first the I/O Interface and than the power supply of the demoboard. 3. Connect the I/O - Interface “D” to a µC or via the austriamicrosystems USB Interface Box to a PC. For interfacing please see the corresponding datasheet of the AS1116.
