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)
Example: SpaceBall 4000¶
