The Implementation of Digital Input System for Cellular-phone using the Accelerometer and PIC

Accelerometer Sensor와 PIC를 이용한 Cellular-phone용 Digital Input System 구현

This paper has been studied about designed digital-pen using PIC and Accelerometer and about calculated acceleration by the measure analog signal from accelerometer Finally, we calculate the coordinates and the tilt about the acceleration and discuss the possibility of using the digital-pen from cellular phone. And we discuss about the full-duplex communication of input data that displayed in cellular phone.
