| Title: |
Pixel Mirror Based Stage Lighting System |
| Abstract: |
A lighting system with a digital micromirror device which forms a digital
godo system that is controllable on a pixel level. The device includes a
number of sensitive electronic elements. The device is controlled by two
different controllers: a digital signal processor which is effectively
the number crunching portion, and a controller, which controls the
functions of the light. The controller also logs errors into a registery,
such as a non-volatile memory. A field programmable gate array is used
for a number of purposes, including to form the ports. One of those ports
is a tech port, which is used to detect status of the light such as
faults.
