Hello all;
I seem to be having a problem writing to ttyO1.
Here is the really simple code and the result on the console:
Code:
var data
var serialPort, sp;
var serialPort = require("serialport").SerialPort;
var sp = new serialPort("/dev/ttyO1", { baudrate: 9600 });
sp.on("open",function(){
console.log("Hello World the Comm Port is Open");
});
function sp_write(data){
sp.write(data,function(err, results) {
console.log('err ' + err + ' What happened? ' + results);
});
}
togglepin();
function togglepin(){
// High and low parts of the frame length (not counting checksum)
sp_write("Hello Again):
//sp_write(0x0);
//sp_write(0x10);
}
And here is the console Output:
Error: Serialport not open. What happened? undefined
Hello World the Comm Port is Open
Anyone got any ideas ??
