Drivers

Function	Description
Init()	Initialize the display. Automatically called on power up.
Mode(direct)	Set the graphics mode to 1-direct, 0-buffered (default).
GetW()	Get display width: 106 in buffered, 320 in direct.
GetH()	Get display height: 80 in buffered, 240 in direct.
IsColor()	Returns 1.
GetX()	Return touch x.
GetY()	Return touch y.
DVer()	This driver version.

By default, the display is initialized in buffered mode.

tip

See Graphics for available drawing functions, such as Text() and Circle().

The Code!

Modules ship with this script preloaded. Use Console to reload or modify the drivers. Additionally, some languages, such as Python, include DUELink.Engine.Record() for recording scripts directly from the host.

Script

Use Console to modify the default driver by adding this sample.

# Append this code at the bottom of the script, right after the driver.
# You MUST keep the driver code!!
