Descriptions
The LC4500 Cape provides a portable DLP projector solution for BeagleBone boards. The WXGA projector, controlled by a TI DLPC350, sits below the LC4500 control board. The Beaglebone plugs in "upside down" to the topside of the board. Trigger and synchronization signals are routed to the BeagleBone to support triggering of events. An SPI bus is routed from the BeagleBone to a connector on the LC4500 to communicate with other devices (such as an ADC). Control of the DLPC350 is accomplished with I2C commands from the BeagleBone.
