Below is the code for the BTC display on the LCD.var Client = require('node-rest-client').Client; var LcdClient = require('lcdproc-client').LcdClient; lc = new LcdClient(13666,'localhost'); function get_bitcoin() { console.log("Get Bitcoin"); client = new Client(); client.registerMethod("jsonMethod", "http://blockchain.info/ticker", "GET"); client.methods.jsonMethod(function(data, response){ // parsed response body as js object var obj = JSON.parse(data); buy = obj.USD['buy']; sell = obj.USD['sell']; lc.widget_val("first_line",1,1,"BTC " ); lc.widget_val("second_line",1,2,"B:" + buy + " S:" + sell); }); } lc.on('ready', function() { console.log("AAA"); console.log("WIDTH: " + lc.width); console.log("HEIGHT: " + lc.height); lc.screen("bacon"); lc.widget("first_line"); lc.widget_val("first_line",1,1,"This is a line"); lc.widget("second_line"); lc.widget_val("second_line",1,2,"This is a second line"); get_bitcoin(); setInterval(get_bitcoin, 300000); }); lc.init(); December 29, 2013| Tags : X Comments Section Feel free to comment on the post but keep it clean and on topic.
