serialEvent not working in osx
[0 Replies]

Forum:
Integration and Hardware
using Tom Igoe's serial event processing code:
and some arduino code that works.
http://www.processing.org/reference/libraries/serial/serialEvent_.html
I have verified that this works just fine under windows.
I have yet to verify if it works under linux.
It does NOT work in osx.
OSX hack:
run the following python script FIRST before processing sketch:
#!/usr/bin/env python
import serial
from time import sleep
s = serial.Serial(port='/dev/tty.usbmodem411', baudrate=9600)
while (1):
sleep(1)
s.write('\n')
l = s.readline().strip()
print l
This will "prime the pump" of processing so to speak.
Obviously, the serialEvent has NOT been tested in osx.
I will verify later today, if the same situation applies to linux
using Serial to communicate with arduino

can someone look at this thread? and clue me in on this?
crossposted thread
does someone have working code in Processing for Serial processing from Arduino ( a line at a time )

I am fairly new to Processing, so pardon the newbie question
I have an arduino program that prints out a csv string val1,val2,val3,val4\n:
int firstSensor = 0;
int secondSensor = 0;
int reset = 0;
int serve = 0;
int inByte = 0;
void setup()
{
// start serial port at 9600 bps:
Serial.begin(9600);
randomSeed(10);
//establishContact(); // send a byte to establish contact until Processing responds
}
void loop()
{
// if we get a valid byte, read analog ins:
if (Serial.available() > 0) {
inByte = Serial.read();
firstSensor = random(385);
secondSensor = random(385);
reset = random(0,2);
serve = random(0,2);
if (reset == 1) {
serve = 0;
}
Serial.print(firstSensor);
Serial.print(',');
Serial.print(secondSensor);
Serial.print(',');
Serial.print(reset);
Serial.print(',');
Serial.println(serve);
}
}
I can read the data in python:
#!/usr/bin/env python
import serial
from time import sleep
s = serial.Serial(port='/dev/tty.usbmodem411', baudrate=9600)
while (1):
sleep(1)
s.write('\n')
l = s.readline().strip()
print l
but I can't get this to work in Processing:
I am trying to use serialEvent and bufferUntil, but no matter what I try, absolutely nothing comes over.
Does anyone have any working code that would take the output of the arduino in processing?
thanks,
Jerry
