Shared library (dynamic base) is an object module (with .so postfix notation), operationally, can be loaded into arbitrary storage address, and gets up with a program chains in memory, and this process is called dynamic link.Dynamic link is performed by a program being called dynamic linker.After shared library generates, write the header file of a .h, this header file comprises the statement of each function in shared library, only need comprise this header file when user writes application program, just directly can call each function in shared library, realize self-defining upper level applications.
In order to meet the demand that distinct program controls message lamp, improving the efficiency that message lamp controls, the present invention proposes a kind of message lamp control method based on Loongson platform.
Summary of the invention
The present invention, in order to make up the defect of prior art, provides a kind of simple, efficient message lamp control method based on Loongson platform.
The present invention is achieved through the following technical solutions:
A kind of message lamp control method based on Loongson platform, it is characterized in that: convert the voltage signal detected to digital signal by control module and send to message lamp control program, and pass through the command signal of message lamp control program transmission, the light on and off of control message lamp, realize the state comprising initial message lamp, message lamp continues setting three functions of flicker and message lamp flashing times; Realizing the state of described initial message lamp, message lamp continues compose-message lamp in the assignment procedure of flicker and message lamp flashing times and controls source program, and compilation message lamp control source program is generated relocatable file destination, and generates shared library; Application program needs directly to call message lamp control program in shared library during control message lamp.
When the state of initial message lamp, first opening device file, then the state of detect-message lamp, when detecting that the duty of message lamp is normal, then being closed, when the working state abnormal of message lamp being detected, then alarm quitting a program.
When setup message lamp continues flicker, first message lamp is turned on, make message lamp bright, then the sleep(time length of one's sleep is set), message lamp is made to enter sleep pattern, the length of one's sleep sleep(time) terminate after, close message lamp, and then make message lamp enter sleep pattern, the length of one's sleep sleep(time) terminate after, the message lamp flashing times of user's setting whether is reached according to message lamp flashing times, select end process or again turn on message lamp to carry out continuing flicker, until process terminates after the message lamp flashing times of completing user setting.
The invention has the beneficial effects as follows: should based on the message lamp control method of Loongson platform, source program is controlled by compose-message lamp, and compiled generation relocatable file destination, and generate shared library, application program needs directly to call message lamp control program in shared library during control message lamp, meet the demand that distinct program controls message lamp, improve the efficiency that message lamp controls.
Accompanying drawing explanation
Accompanying drawing 1 generates shared library and dynamic link schematic flow sheet for the present invention;
Accompanying drawing 2 is for the present invention is based on the message lamp control method schematic flow sheet of Loongson platform.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present invention, and below in conjunction with accompanying drawing, the present invention is described in detail.
Should based on the message lamp control method of Loongson platform, convert the voltage signal detected to digital signal by control module and send to message lamp control program, and pass through the command signal of message lamp control program transmission, the light on and off of control message lamp, realize the state comprising initial message lamp, message lamp continues setting three functions of flicker and message lamp flashing times; Realizing the state of described initial message lamp, message lamp continues compose-message lamp in the assignment procedure of flicker and message lamp flashing times and controls source program, and compilation message lamp control source program is generated relocatable file destination, and generates shared library; Application program needs directly to call message lamp control program in shared library during control message lamp.
When the state of initial message lamp, first opening device file, then the state of detect-message lamp, when detecting that the duty of message lamp is normal, then being closed, when the working state abnormal of message lamp being detected, then alarm quitting a program.
When setup message lamp continues flicker, first message lamp is turned on, make message lamp bright, then the sleep(time length of one's sleep is set), message lamp is made to enter sleep pattern, the length of one's sleep sleep(time) terminate after, close message lamp, and then make message lamp enter sleep pattern, the length of one's sleep sleep(time) terminate after, the message lamp flashing times of user's setting whether is reached according to message lamp flashing times, select end process or again turn on message lamp to carry out continuing flicker, until process terminates after the message lamp flashing times of completing user setting.
The present invention is based on the message lamp control method of Loongson platform, specific implementation step is as follows:
1, the state of initial message lamp: the status information first reading information lamp, namely under the system that opens file/dev/loongson1-gpio, if open successfully, then according to the GPIO value of message pilot lamp, obtain the state of message lamp, if message lamp duty is normal, then in/dev/loongson1-gpio, writes 0, close message lamp.
2, message lamp is set and continues flicker: the state first reading message lamp, under the system that namely opens file/dev/loongson1-gpio, if open successfully, then according to the GPIO value of message lamp, read the state of message lamp, judge whether message lamp occurs exception; If message lamp is working properly, then allow message lamp bright, namely in/dev/loongson1-gpio, 1 is write, then sleep operation is performed, the message lamp sleep(time bright length of one's sleep) close message pilot lamp afterwards, namely in/dev/loongson1-gpio, write 0, then sleep operation is performed, message lamp is allowed to go out the sleep(time length of one's sleep), circulate this operation, can see that message lamp does not stop flicker.Circulation performs this process n time (n is the message lamp flashing times that user sets), namely can see message lamp flicker n time.
3, after programming terminates, perform compiler directive: gcc-osignallight.o-csignallight.c – fPIC, compiling is by rear fill order: gcc – shared – oliblight.sosignallight.o, finally generates shared library liblight.so.
4, the function name realized in above-mentioned steps is write in light.h header file, when the self-defined application program of user needs control message lamp, only need to comprise light.h header file in a program, and liblight.so is placed on the position at application program source program place.
