Infineon Powering the Future -
Voice activated switch for DC powered actuators
 
 Transistor IPT60RO28G7 is connected via optocoupler to XMC1100 TSOP16
  The cathode of the diode in the optocoupler is connected to P2.10. The anode is connected to      *  3.3V via a 330 Ohm resistor.
 Commands are received through the serial interface on the Debug module.
 Tx is at P2.0 and Rx is at P2.6
 Transistor switches to 12V a headlamp LED.
