To use HDJD-JD06 in transmissive mode, the white LED
should be turn off with the slider switch at the color sen-
sor controller board.
3.1 Color Sensor Controller Board
The color sensor controller board consists of the follow-
ing modules:
This module converts the analogue voltage to digital
output, and then from 2-wire serial interface to USB pro-
tocol that can be easily interfaced with the computer. The
ADC has 10-bit resolution. Upon power up, the ADC will
start taking in 3-channel color sensor output (Vr,Vg,Vb)
and perform A/D conversion. The digitized value will be
read by the microcontroller via the 2-wire serial inter-
face which is then sent to Avago sensor development
kit program via USB upon completion of each round of
conversion.
The main components of this module are HDJD-J822 as
