Hello friend. I think maybe is too late for you, but if someone is alredy
looking for information about that, i took the solution.
In the bonescript library i didn't find a function to append in a text
file, so i used the function appendFile(), from node.js library. To use
this function, we have to write var fs = require('fs');
In my code, i read the value of a pin and i write this value on a text
file, append to the other values. This is my code:
var b = require('bonescript');
*var fs = require('fs');*
b.pinMode('P9_11', b.INPUT);
setInterval(copyInputToFile, 1000);
function copyInputToFile() {
b.digitalRead('P9_11', writeToFile);
function writeToFile(x) {
b.echo(x.value);
* fs.appendFile('datos.txt', x.value);*
}
}
I hope you find it useful.
