Software
To use the AS1116 single-color Demoboard a controller is required. The controller can be connected to the
demoboard via the I/O Connector
“E”.
If no controller is available the austriamicrosystems USB box in combination with the AS1116 single-color
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.
Operational sequence
This demo board comes with one AS1116.
1.
2.
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.
First connect the power supply via connector
“C”
to a powered USB port and than power up the I/O -
Interface
“E”.
To power down the system disconnect first the I/O Interface and than the power supply of
the demoboard.
Connect the I/O - Interface
“E”
to a µC or via the
austriamicrosystems USB Interface Box
to a PC. For
interfacing please see the corresponding datasheet of the AS1116.
