HiJack Oscilloscope

Description

HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone. HiJack devices harvest power and use bandwidth from the mobile phone's headset interface. The HiJack platform enables a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation.

This application provides a simple oscilloscope demonstration. The HiJack device samples the ADC6 port and sends the data over the headset port to the application. The application acts like an oscilloscope, and displays the readings. A slider on the bottom of the oscilloscope changes the sampling rate from a few readings per second, to about 100Hz.
