IRTouch Recommendations

• Setting of touchscreen in strong light, rain and snow condition(As reference)
• The snow and rain drop will be mistakenly a single touch. The function of "delayTouch" will do the work to prevent the false touch.

Settings Specification:

• Alter "delayTouchTime" in /etc/irtouch and set the value from 10 million second to 1000 million second, common value :40-80 million second based on the condition.
• Be sure not to start delayTouch if the value is 0.

Touch response The touch response can not be active if delayTouch function is on.
