Primary Events
The Primary Events described below are the default behavior. Primary events can be modified using the LXEPower-
MgrPrimaryEvents API.
Please refer to the CE API Programming Guide for API details.
User Primary Events
A User Primary Event transitions the Thor VM1 to D0 (On) mode. When no user event happens for the specified
time period, the Thor VM1 transitions to D1 (User Idle), then D2 (System Idle) and then D3 (Suspend). Timeout
periods are set via the Schemes tab in the Power control panel.
User primary events include:
• Any key press on the keypad
• Touch on the touch screen
• USB data entry (from a USB keyboard or mouse)
System Primary Events
A System Primary Event allows the Thor VM1 to transition to D2 (System Idle) but the Thor VM1 does not enter
D3 (Suspend) as long the system event occurs.
System primary events include:
• Serial data transfer
• USB data transfer
Wake Source Events
These events wake the Thor VM1 from suspend:
• Power button
• Touch on the touch screen
• Any key press on the keyboard
• USB connect / disconnect
• Truck power on or off (i.e. ignition key)
•RTC
• Bluetooth connection
• External power connection
• Serial port CTS control line
• Headset connection (this is not enabled by default, but can be configured to wake the Thor VM1)
Events generated by these actions are not processed. For example, the touch screen tap that wakes the Thor
VM1 is ignored.
The following events DO NOT wake the Thor VM1 from suspend:
• Bluetooth keyboard or mouse
• USB host data (unless enabled via API)
• USB host connection
• SDIO interrupt
• Serial data
• 802.11 radio
• External power disconnect
