Abstract

The invention relates to an integrated device for detecting, identifying and charging a four-color pen and an eraser, and a related method. The device comprises a main controller, and is characterized by also comprising a pulse width modulation (PWM) timer, an analog channel control switch, a pen electric quantity detecting and charging circuit and analog/digital (A/D) channels which are in signal connection with the main controller respectively. The A/D channels are switched to measure the electric quantity of the pen, the charging of multiple channels and the identification and detection of the pen are combined and integrated, the device has a simple structure and low cost and is reliable, and software and hardware are relatively easy to implement.

Description

technical field [0001] The invention relates to the technical field of electronic whiteboard products, more specifically, to an integrated device for detecting and charging a four-color pen and an eraser, and a method for detecting power and state. Background technique [0002] The current electronic whiteboard writing method provided by the prior art only has a single colorless electromagnetic pen, and does not have the function of automatically identifying multiple pens and multiple colors. When the user needs to write with pens of different colors during the electronic whiteboard writing process, the current The electronic whiteboard writing method cannot meet the requirements. Moreover, the functions of real-time power detection and real-time charging of the pen cannot be achieved. The electronic whiteboard provided by the prior art does not require the traces written by the pens to be stored locally, that is, to be used by a single machine. When the user needs to store...
