STREAMING DATA

Press the Play button to begin streaming data from the evaluation

board. Move an object or hand within 15 cm above the

ADUX1020

to see the corresponding output of the device on the

graphs. The Y Ratio vs X Ratio graph shows the calculated x, y

position of the object above the device (see Figure 7). The Intensity

graph shows the average intensity of reflected light seen by the

device, represented in ADC codes.
