Abstract

A method for avoiding collision in command transmission includes starting up special I / O port, transmitting command to extension interface module by master system through I / O port, using embedded controller to analyze and execute command received by extension interface module and feeding executed result back to maser system by said embedded controller after command is executed. The electronic device used for realizing said method is also disclosed.

Description

【Technical field】 [0001] The invention relates to a method for avoiding command transmission conflicts and an electronic device thereof. 【Background technique】 [0002] As shown in FIG. 1 , an electronic device 1 , such as a notebook computer, includes a main system 10 , an embedded controller 12 , and an input terminal 14 (such as a touchpad, keyboard, mouse, etc.). The input terminal 14 is connected to the embedded controller 12 to transmit user's operation commands to the embedded controller 12 . The host system 10 is connected to the embedded controller 12, and the host system 10 can call the embedded controller 12 to execute commands. [0003] As shown in FIG. 2 , the embedded controller 12 in the prior art includes: a keyboard control interface module 122 and an embedded control interface module 124 . The keyboard control interface module 122 is connected to the main system 10 through the input / output port 102 of the keyboard controller, and is used to transmit the c...
