BoneScript
You might be able to see a newer version of this on beagleboard.org/support/bonescript/digitalWrite
digitalWrite(pin, value, [callback])
Write a HIGH or LOW to a digital I/O pin.
NOTE: The 4 USRx LEDs are all able to operate as digital output pins, giving you an always-available output to test your software.
Arguments
- pin: the BeagleBone pin identifier
- value: the logic level to set the pin
- callback: called upon completion
Return value
callback(x)
- x.err: error status message
Example
var b = require('bonescript');
b.pinMode('USR0', b.OUTPUT);
b.digitalWrite('USR0', b.HIGH);
Build and execute instructions
- The USR0 LED is built in, so no circuit assembly is required.
- Look for it to go high when you run the example code.
- Alter the code to set it low and run it again.
