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.

# Interrupt mode: 
#   Return button state by interrupt. A read clear last value to 0.
#   If no read, the last value change will be kept for two seconds then reset to 0 if no read. 

# Direct mode:
#   Return button state as is

_m = 0 # 0: interrupt - default, 1: direct mode

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!!
