Abstract

A method and system for error detecting is provided for the error detecting process in an error detecting servo host and an electronic device. The servo host and electronic device both include a memory unit for storing an error-detecting program and plurality of error detecting code, and a controller having at least one PWM (pulse width modulation) pin and one GPIO (general purpose input/output) pin. Before detecting error toward the electronic device, the GPIO pin and the PWM pin of the servo host need to be connected to the PWM pin and the GPIO pin of the electronic device, respectively. Then the electronic device executes the error-detecting program for sending error-detecting data and the servo host executes the error-detecting program for receiving the error-detecting data, simultaneously. The error-detecting data of the electronic device can therefore be displayed on the servo host thru the pins connected there between.
