TSPTT is a simple project to link up a physical switch, via an Arduino to the PC in order to trigger the PTT on a VoIP program (e.g. TeamSpeak, hence "TS").
The Arduino program is small and just prints a 0 or 1 to the USB->serial connection whenever the state of the switch changes, making it easy to read from the PC.
On the PC, I tried Gobetwino, a closed-source "proxy" that parses commands sent over serial to the Arduino. Unfortunately it can't hold keys down, only press them, at which point I found Rajarshi Roy's blog post on the same subject.
Rajarshi pointed out the Java
API (java.awt.Robot
) for key presses, in order to trigger the
PTT. Along with the rxtx serial Java
library, this makes up TSPTT.
The
code simply installs a systray icon, monitors the serial port and applies
key presses and releases as required.
My TSPTT JAR is available here, set up for F5 as the PTT and COM3 or /dev/ttyUSB0 as the serial port (rxtx must be installed too).
