The
ASIC
box gives the user access to the various parameters that can be controlled on the
output of the SMD USEQ*S sensor.
•
Gain:
The gains should all be set equal on every channel for gesture detection. They
are allowed to be set independently simply to allow the user complete control over
every aspect of the device that can be set. The gain is set by selecting a capacitor to
be used in the charge amplifier within the device.
•
HPF:
The high pass filters should again be set equal for gesture detection.
•
Transconduct:
The transconductance gives the user the ability to set the time
constant of the sensor and amplifier set-up.
•
LPF:
The low pass filter used is common to all channels of the SMD USEQ*S sensor.
•
Sampling Period:
This allows the sampling rate to be altered.
4.4.3 Wake-Up Tab
The
Wake-Up
box allows the setting of the wake-up conditions for the device. The wake-up
only applies when the device is in sleep mode.
•
The wake-up works by requiring the signal to be within the range of threshold 1
and 2 or within threshold 3 and 4 for a certain number of samples.
•
The number of samples required is in the top right box.
•
The channel that is being used for the wake-up condition is selected in the box
above the
Apply
button.
