Touch Screen

The options on this screen can be used to reduce the CPU and power consumption of the HX2.

Bulk Samples

Bulk Samples is the number of touch screen samples taken per cycle, with high and low values discarded. The default is 8. Lowering this value reduces the amount of CPU usage devoted to touch screen processing.

Sample Rate

Sample rate is the frequency with which the touchscren samples are taken. The default is 67.3Hz. Lowering this value reduces the amount of CPU usage devoted to touch screen processing.

Display Power Save Mode

When using the Default option, the operating system turns off power to the display when the HX2 is in system idle or suspend modes. When the Low option is used, the operating system does not cut power to the display. Instead the power management feature of the display controller is used during system idle and suspend modes.
