Communicating NXP LPC800 and Smart phone with Audio Jack
The NXP Quick-Jack app enables communication from your smartphone to the NXP LPC800 Quick-Jack board. The NXP Quick-Jack solution repurposes the standard 3.5 mm stereo audio jack found on most smartphones into a self-powered data channel that makes communication with these devices as easy as plugging a headset jack into the audio port. This allows hardware to communicate with a smartphone in a simple way and at low-cost.
