Analog to Digital Converter Board
The Analog to digital converter board comprises of the following components:
As the name implies, its function is to perform A/D conversion with 10-bit resolution. Upon power up,
the color controller 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 Avago sensor development kit program via parallel
upon completion of each round of conversion.
Shown in the following Figure 3.6 is the diagram of the A/D board:
