I have downloaded github library and install all need libraries with latest serialport.
I have made following changes into sbi-httpd.js to make compatible with new serialport parser changes.
// Changes begins.
//
// default error handler (just throws the error)
//
function throwIt(err){
if (err) throw new Error(err);
}
class Scale extends Emitter {
constructor( options, callback ) {
super();
let scale = this;
scale.options = Object.assign({}, TTY_DEFAULTS, options || {});
scale.responseHandler = undefined;
const Regex = require('@serialport/parser-regex')
scale.tty = new SerialPort( scale.options.ttyDevice, {
//"parser": SerialPort.parsers.readline("\r\n"),
"autoOpen": false,
// defaults
"baudRate": scale.options.baudRate,
"dataBits": scale.options.dataBits,
"stopBits": scale.options.stopBits,
"parity": scale.options.parity,
"rtscts": scale.options.rtscts,
"xon": scale.options.xon,
"xoff": scale.options.xoff,
"xany": scale.options.xany
});
const parser = scale.tty.pipe(new Regex({ regex: /G\s{5}([-+\s]{1})\s([\d\.\s]{8})\s([\w\s]{3})\r\n/ }))
// Changes ends
Now when I run sbi-httpd.js with node command. I get following error.
Unable To Connect To Serial Port
