pinMode(pin, direction, [mux], [pullup], [slew], [callback])

Note: This function doesn't work until BoneScript version 0.2.3

This function configures the mode of a digital I/O pin.

Arguments

• pin: the BeagleBone pin identifier
• direction: INPUT, INPUT_PULLUP (under development on 3.8 kernel) or OUTPUT
• mux: index to mux mode (under development on 3.8 kernel)
• pullup: 'pullup', 'pulldown' or 'disabled' (under development on 3.8 kernel)
• slew: 'fast' or 'slow' (under development on 3.8 kernel)
• callback: called upon completion

Return value

• true if successful
• false on failure

callback(x)

• x.value: return value
• x.err: error status message

Example run restore

var b = require('bonescript');
b.pinMode("P8_13", b.OUTPUT, 7, 'pullup', 
 'fast', printStatus);
b.getPinMode("P8_13", printPinMux);
function printStatus(x) {
    console.log('value = ' + x.value);
    console.log('err = ' + x.err);
}
function printPinMux(x) {
    console.log('mux = ' + x.mux);
    console.log('pullup = ' + x.pullup);
    console.log('slew = ' + x.slew);
    console.log('options = ' + x.options.join(','));
    console.log('err = ' + x.err);
}
