SQUAL
Address: 0x05
Access: Read
Reset Value: 0x00
Data Type: Upper 8 bits of a 10-bit unsigned integer.
USAGE: SQUAL (Surface Quality) is a measure of of the number of valid* features visible by
the sensor in the current frame. Use the following formula to find the total number of valid
features.
Number of features = SQUAL register value *4
The maximum SQUAL register value is 169. Since small changes in the current frame can result
in changes in SQUAL, variations in SQUAL when looking at a surface are expected. The graph
below shows 250 sequentially acquired SQUAL values, while a sensor was moved slowly over
white paper. SQUAL is nearly equal to zero, if there is no surface below the sensor. SQUAL is
typically maximized when the navigation surface is at the optimum distance from the imaging lens
(the nominal Z-height).
