Abstract
The invention provides a method for transmitting encoded infrared rays through a PC. According to the method, a keyboard, a main board, a USB port, an infrared emitting tube and a power source of the PC are used, under the support of software, the PC can have the encoded infrared ray transmitting function, electronic equipment can be controlled remotely by operating the keyboard, therefore, infrared remote operation is simple and convenient to achieve and efficient, and convenience is achieved.
Description
Technical field
The present invention relates to PC, particularly relate to a kind of by the ultrared method of PC launching code.
Background technology
At present, the PC on market does not have the ultrared function of launching code, and remote controlled electronic device sometimes can feel inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of by the ultrared method of PC launching code, the method is utilized keyboard, mainboard, USB interface, infrared transmitting tube, the power supply of PC, under software support, can solve PC and there is no the ultrared function of launching code, sometimes remote controlled electronic device, can feel inconvenient problem.
for achieving the above object, technical scheme of the present invention is as follows:
A kind of by the ultrared method of PC launching code, described PC comprises, keyboard, mainboard, USB interface, infrared transmitting tube, power supply, mainboard is connected with power supply, keyboard, USB interface respectively, described USB interface is also connected with infrared transmitting tube, power supply is to keyboard, mainboard, USB interface, infrared transmitting tube power supply, and described method, comprises the following steps:
A, initialization;
B, operation master routine;
C, operation keyboard produce scan code, and this scan code is sent into 60H port and caused int9 interruption, jumps to b step while not having button;
D, CPU carry out int9 and interrupt processing keyboard input, read the scan code in 60H port, and this scan code is not the scan code of Esc key, jumps to g step;
E, the negate of launching code infrared ray discrimination bit;
F, interruption are returned;
G, launching code infrared ray discrimination bit are not 0, jump to j step;
H, interruption are returned;
J, call the coding infrared emitting driven element program corresponding with scan code in 60H port;
K, this subroutine drive infrared transmitting tube by USB interface, the infrared ray of launching code;
M, interruption are returned.
beneficial effect of the present invention:
The present invention is a kind of by the ultrared method of PC launching code, the method is utilized keyboard, mainboard, USB interface, infrared transmitting tube, the power supply of PC, under software support, can make PC have the ultrared function of launching code, operation keyboard just can remote controlled electronic device, thereby make infrared remote-control operation become easy and efficient, can feel convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the present invention is a kind of with the ultrared method workflow diagram of PC launching code.
Embodiment
In order to further illustrate principle of the present invention and structure, existing by reference to the accompanying drawings to a preferred embodiment of the present invention will be described in detail, but described embodiment is only for furnishing an explanation and the use of explaining, can not be used for limiting scope of patent protection of the present invention.

A, initialization;
B, operation master routine;
C, operation keyboard produce scan code, and this scan code is sent into 60H port and caused int9 interruption, jumps to b step while not having button;
D, CPU carry out int9 and interrupt processing keyboard input, read the scan code in 60H port, and this scan code is not the scan code of Esc key, jumps to g step;
E, the negate of launching code infrared ray discrimination bit;
F, interruption are returned;
G, launching code infrared ray discrimination bit are not 0, jump to j step;
H, interruption are returned;
J, call the coding infrared emitting driven element program corresponding with scan code in 60H port;
K, this subroutine drive infrared transmitting tube by USB interface, the infrared ray of launching code;
M, interruption are returned.
Described embodiment advantage and beneficial effect are, the present invention is a kind of by the ultrared method of PC launching code, the method is utilized keyboard, mainboard, USB interface, infrared transmitting tube, the power supply of PC, under software support, can make PC have the ultrared function of launching code, operation keyboard just can remote controlled electronic device, thereby makes infrared remote-control operation become easy and efficient, can feel convenient.
The just embodiment of invention described above; various not illustrating limited essence of an invention Composition of contents; person of an ordinary skill in the technical field read after instructions can to before described embodiment make an amendment or be out of shape, all should be considered as belonging to protection scope of the present invention.
