Abstract
A method for simulating a physical-keyboard signal includes executing a monitoring program in an operating system, receiving at least one input key code signal by the monitoring program, sending the input key code signal to an embedded controller, looking up a key mapping table by the embedded controller according to the input key code signal to obtain a keyboard scan code signal corresponding to the input key code signal, sending the obtained keyboard scan code signal to the operating system, and performing a corresponding function by the operating system according to the keyboard scan code signal.
Claims9
A system for simulating a physical-keyboard signal, comprising:
- a signal source terminal, for sending an input key code signal;
- a storage unit, having a monitoring program and an operating system;
- a processor, executing the monitoring program and the operating system;
- and
- an embedded controller, having a key mapping table, the key mapping stable recording a plurality of keyboard scan code signals, each input key code signal corresponding to one of the keyboard scan code signals;
- wherein, when the monitoring program is executed, the processor determines whether the input key code signal sent by the signal source terminal is a virtual key code signal or the keyboard scan code signal, and sends the input key code signal determined as the virtual key code signal to the embedded controller, so that the embedded controller looks up the corresponding keyboard scan code signal according to the received input key code signal, and sends the obtained keyboard scan code signal to the operating system.
