Hi Everyone!
I hope someone can help me with this issue - I’m nota able to get data from Parallax RFID reader! Since I update my debian image ( created new with lastest build ). I use 4dsystem 7lcd and my reader is connected to UART4 pin P9_11. Strangest about this is that when I plugin and plugout couple of times it starts get a bytes… Would someone please explain how to get it working all the time?
I define port in cloud9 script
`
…
var RFIDPin = “P9_11”,
enableRFIDPin = “P8_19”,
RFIDport = ‘/dev/ttyO4’;
b.serialOpen(RFIDport, options, onSerial);
function onSerial(x) {
setTimeout(function() {
if (x.err) {
console.log('ERROR ’ + JSON.stringify(x));
}
if (x.event == ‘open’) {
console.log(‘OPENED’);
}
if (x.event == ‘data’) {
processTags(x.data);
}
},500);
return true;
}
function processTags(symbolByte) {
var char = String(symbolByte);
console.log(char);
var charCode = parseInt(char.charCodeAt(0));
if(charCode === 10 && lastCharCode === 13)
allow = true;
if(allow) {
if(compareTag.length < 11) {
compareTag += char;
} else {
allow = false;
compareTags();
}
}
lastCharCode = charCode;
return true;
}

Do I need change pinMux from default one and if yes, how to do that?
Thanks,
Ingus
