New demo example is uploaded on PIC32-PINGUINO-MX220 web page which demonstrate how to add GSM remote control to Pinguino and place and receive GSM calls.
PIC32-PINGUINO-MX220 have UEXT connector which allow MOD-GSM to be connected and easy to add cellular remote control.
The demo code contain PDE sketch which take calls and if the call is from GSM phone which is known toggle the on board LEDs (or if you attach relay can open your garage door for instance). If the on board button is pressed Pinguino will call stored phone number (i.e. panic button, or alarm event).
The demo code is at http://www.olimex.com/dev/DUINO/PIC32-PINGUINO-MX220/PIC32MX220_MODGSM_call_example.zip
