Digital Color Sensor Controller Board
The digital color sensor controller board consists of the
following modules:
(i)
(ii)
(iii) LED Constant Current Module
(iv) Digital Color Sensor Control Module
2-wire Serial Interface to USB Converter Module
This module converts the 2-wire serial interface from the
digital color sensor to USB protocol that can be easily
interface with the PC. The main components of this
module are dual bidirectional bus buffer, P82B96 and
USB microcontroller, PIC18F2455. The P82B96 interface
the two different logic level from the microcontroller (5V)
and digital color sensor (2.6V) while the microcontroller
interface the 2 wire serial to USB.
