Hello,
I am using a beaglebone Black Rev C
I am trying to run a simple program to make an led ON with a push
button.But getting this error
/usr/local/lib/node_modules/bonescript/my.js:57
if(slot[0]) {
^
TypeError: Cannot read property '0' of null

My code is....
var b = require('bonescript');
var led = "P9_14";
var button = "P8_11";
b.pinMode(led, b.OUTPUT);
b.pinMode(button, b.INPUT);
var state = b.LOW;
b.digitalWrite(led, state);
b.attachInterrupt(button, true, b.CHANGE, toggle);
function toggle(x) {
if (x.value == b.HIGH) {
console.log("The button is HIGH");
b.digitalWrite(led, b.HIGH);
}
else {
console.log("The button is LOW");
b.digitalWrite(led, b.LOW);
}
}
I am getting this error by making the P9_14 an output..
