Both worked fine until I updated to OS X Lion. Do you know what the problem is? This is the error log from Processing: ava.lang.NullPointerException at processing.serial.Serial.write(Serial.java:521) at sketch_jan05a.draw(sketch_jan05a.java:145) at processing.core.PApplet.handleDraw(PApplet.java:1606) at processing.core.PApplet.run(PApplet.java:1503) at java.lang.Thread.run(Thread.java:680) Thanks in advance.

Glad to see someone has gotten them to work together. Thanks for the effort... I'm excited to keep exploring.

I was jsut going through some programming codes and I don't know how to sync those codes with the chronos.. Any help will be appreciated. Cheers, Ramesh Hi,

Cool to see there is now a Processing variant as well! Just to clear things up about the 'ACC' and 'PPT' mode of the watch: in ACC mode, the buttons are 17, 49 and 33, while in PPT mode, they are 18, 50 and 34 (at least on my watch). So, it seems that in PPT mode, the values for the buttons are incremented with 1 compared to the ACC mode. This could be exploited in some program on the pc, since now we can pretend that there are 6 different control buttons. Cheers Admar Hi!
