Has anyone had any success communicating with an Arduino microcontroller with ImageJ (yes, I know MicroManager is supposed to be able to do it, but MM can't be used at the current time).
I'd like to use the "Serial port Macro Extensions" plugin (
http://imagejdocu.tudor.lu/doku.php?id=plugin:utilities:serial_macro_extensions:start from
http://rsbweb.nih.gov/ij/plugins/index.html) to communicate with an Arduino Uno to grab analog voltages while capturing images at various times. I seem to have things properly set now so that I can still run the Arduino development environment to program my board while having ImageJ open for interactive troubleshooting, but while the plugin's instructions tell the user how to address the port ('COM1', 'COM2', etc.) under Windows, there's no mention of the proper syntax to use under Mac OS X (running 10.6.5).
I've tried the usual "/dev/tty.usbmodem1d11" (usual for OS X; "COMx" doesn't work either) and some variations, but it doesn't seem to want to cooperate.
The macro doesn't crash, so I can figure I have no port conflicts - I'm just not specifying it properly to the plugin.
Sample macro I'm using (while the Uno is slamming out ASCII characters 20h-7Fh followed by a 10h, at 9600/8/N/1):
run("serial ext");
Ext.open("/dev/tty.usbmodem1d11",9600,""); //or: Ext.open("COM1",9600,"");
ports = Ext.ports(); print("ports ="+ports+".");
active = Ext.active(); print("active ="+active+".");
data = Ext.read(); print("data ="+data+".");
'Log' window results:
ports =.
active =0.
data =.
(the periods show me there are no hidden characters)
Comments? Ideas? Fixes? Thanks.
