Library to handle SpaceBall, SpaceMouse and SpaceOrb on serial port. Gets access to 3D rotation and translation vector as well as button status. (USB is not supported)
Serial Connection
To connect any serial SpaceBall or SpaceMouse or SpaceOrb to a mbed device a RS232-driver is used like the MAX3232.
The SpaceBall gets its power from the D-Sub connector at pin 4 and/or 7. The Driver is used to produce about 9 volt. If you have a power supply with 9 to 12 volt, you can connect directly to pins 4 and 7. The spaceball needs about 5 mA.
Adapter to connect a spceball to mbed¶
Connect the TXD and RXD pins to any serial port on the mbed. Use a male D-Sub connector to plug the spaceball in. The capacitors depends on the used RS232-driver (see datasheet)
