Progress:

1.- downloaded mono for mac (needs X?)
http://www.go-mono.com/mono-downloads/download.html

Gtk#, MonoDevelop, and System.Windows.Forms applications require X11. Installing on a machine without X11 installed will result in errors during install, and these components will not function correctly.

2.- downloaded driver (intel), restart
http://www.ftdichip.com/Drivers/VCP.htm

3.- port: when chronopic3 it's connected, it creates /dev/tty.usbserial-.... (complet name is always the same i the same computer)

4.- downloaded zterm, don't know how to use, the screen:

http://www.macosxhints.com/article.php?story=20061109133825654

exit is ctrl-a k

execute with

screen /dev/tty.usbserial-.... 38400 (or 9600 or...)

zterm works with 38400 N81

5.- playing with chronojump_mini, console.write and changing timeouts

do with 9600 bauds:

parity? Ricardo says: 8N1 (no parity)

we get data with screen and zerm when chronopic3 test button is clicked, but we cannot translate it yet. Try to do it with C examples for Mac:

6.- play with a compile C examples: chronopic-tests for Mac
