Snowpad‎ > ‎

3. Advanced

Parameters

mutScanTime (mutual scan time)

Number of mutual readings to sum per node.
Increasing this value will make Snowpad robust to electrical noises but slow down touch detection speed.
Default values is 0x07.

mutTouchThres (mutual threshold)

Threshold at which a touch may be present.
Increasing this value will make Snowpad robust to electrical noises and increase touch detection speed. However, too high value will cause loss of weak touches.
Default value is 0x23.

numOfAvg (numbe of averages)

Number of previous touch coordinates to average with current position coordinate (smoothing filter).
Increasing this value will give smooth touch movement by sacrificing quick response.
Default value is 0x04.

selfScanTime (self scan time)

Number of self reading to sum per electrode.
Increasing this value will make Snowpad robust to electrical noises but slow down touch detection speed.
Default value is 0x06.

selfTouchThres (self threshold)

Threshold at which a touch may be present
Increasing this value will make Snowpad robust to electrical noises and increase touch detection speed. However, too high value will cause loss of weak touches.
Default value is 0x28
