Abstract
The present invention relates to a method for fast developing a man-machine interactive interface on embedded type Linux of a television and comprises the following steps that a compile switch is set firstly, which indicates that current development is carried out on PC or a television hardware platform; when the current development is carried out on PC, a development platform restricts a PC screen display area into a hardware displaying area via a bottom application program, and thereby, a hardware OSD (On Screen Display) device is simulated out; when the hardware platform is connected and a frame buffer is initialized, a buffer zone corresponding to the hardware displaying area is divided from television hardware via the compile switch, and the buffer zone is mapped into a frame buffer device. The fast development can be carried out on the embedded type Linux of the television via the method. Development can be carried out without a hardware platform and the development cost is lowered. The debugging is carried out by a computer when the development is carried out, which is convenient and fast. A program can be fast transferred on the hardware platform after the development is completed, which saves time.
Description
[technical field]
The present invention relates to the embedded OS field, especially relate to a kind of method of developing fast at the enterprising pedestrian's machine interactive interface of TV set embedded Linux (GUI).
[background technology]
Traditional man-machine interface exploitation is: adopt the commercial version GUI of the complete moulding of a cover, carry out application and development on hardware platform.Generally all have complete on this type systematic and display system fast, need computer and embedded system hardware platform to be used during exploitation.
And in television set, using, employing be the built-in Linux of lightweight, if adopt business level GUI, the OSD display speed of television set is fast inadequately.And the development progress of television set has strict requirement, if adopt traditional development mode, before hardware platform is unripe, can not develop basically.
Among the Linux more than the 2.2.X version, the UDI that a kind of Frame of being called Buffer is arranged, it can be understood as " frame buffering ", be meant the mapping of the shown content of graphics device in video memory, can take out a kind of Frame Buffer equipment thus, it is that graphic hardware equipment is a kind of abstract, uses FrameBuffer and graphic hardware to set up contact, is the interface that the user enters graphical interfaces.FrameBuffer has been arranged, and application program of user does not need can make good figure to just understanding in depth of the driving of bottom.
But FrameBuffer only only provides simple abstract, needs the developer to do upper layer application voluntarily.Under embedded environment, graphical development is the comparison difficulty, and is especially for the exploitation of display device at a slow speed, all the more so.
Therefore, set up a cover efficient, be suitable at a slow speed that the development mode of display device seems extremely necessary.
[summary of the invention]
The object of the present invention is to provide a kind of method of developing fast at the enterprising pedestrian's machine interactive interface of TV set embedded Linux (GUI).
For achieving the above object, the present invention proposes a kind of method of developing fast at the enterprising pedestrian's machine interactive interface of TV set embedded Linux, it is characterized in that comprising the steps:
A, at first a compiler toggle is set, shows that current exploitation is in PC and goes up still on the television set hardware platform;
B, when being in PC and going up, the application program of development platform by bottom is defined as the zone that hardware shows with the on-screen display (osd) area of PC, i.e. the OSD viewing area of television set, thereby simulate the OSD device of a hardware;
C, when connect going up hardware platform, by this compiler toggle, when initialization frame cushion, from television set hardware internal memory, divide earlier one with the corresponding buffering area in hardware viewing area, and this block buffer become the frame buffer device by mapping.
The present invention also comprises following subordinate feature:
Also comprise local updating mechanism, only upgrade the part that modification is arranged, comprise the steps: behind corresponding mapping operation, to set up drawing coordinate to detect, after finishing, drawing obtains the zone of all modifications, when the zone is accumulated to a certain size, perhaps upper layer application is thought when needing to upgrade, and the zone that is modified is sent to hardware OSD equipment, finishes drawing.
In step B, in the time of on being in PC, development platform is introduced into the pattern of 800X600X32.
Compared with prior art, the present invention has following advantage: can be in the enterprising pedestrian's machine interactive interface of TV set embedded Linux (GUI) exploitation fast by this method.Do not need hardware platform during exploitation, reduced development cost; Debug by computer during exploitation, convenient and swift.Can promptly transfer on the hardware platform after exploitation is finished, save time.
Owing to a cover is arranged at the update mechanism of OSD at a slow speed, makes GUI response speed on TV increase substantially.

[embodiment]
Embodiment one:
See also Fig. 1:
The present invention the enterprising pedestrian's machine interactive interface of TV set embedded Linux (GUI) fast the method for exploitation be to cushion by set up a zone at internal memory with the identical size of display screen, realize the mutual butt joint of Frame Buffer and hardware platform.By this buffering area, upper layer application and bottom hardware platform are isolated fully, and upper layer application similarly is at operation Frame Buffer equipment, needn't consider the realization situation of bottom.
A compiler toggle at first is set, shows that current exploitation is on the last still television set hardware platform of PC (Personal Computer).
In the time of on being in PC, development platform is introduced into the pattern of 800X600X32, and the application program by bottom is defined as the zone (the OSD viewing area of television set) that hardware shows with the on-screen display (osd) area of PC, thereby simulates OSD (the On Screen Display) device of a hardware.Its benefit is: there is not any difference in the method exploitation when all upper layer application go up exploitation Frame Buffer application program according to PC.Developing application on this can break away from hardware platform, and can see the effect on hardware platform in real time.
When hardware platform is gone up in connection, by this compiler toggle, when initialization Frame Buffer, from television set hardware internal memory, divide one and the corresponding buffering area in hardware viewing area earlier, and this block buffer is become Frame Buffer equipment by mapping.Like this, with respect to upper procedure any variation does not take place.
For with hardware on the OSD display device interfaces, and accelerate display speed, at television set OSD design one cover local updating mechanism at a slow speed, only upgrade the part that modification is arranged especially.Specifically: behind corresponding mapping operation (setting-out, picture frame, pinup picture), set up drawing coordinate to detect, after finishing, drawing obtains the zone (being generally the rectangular area) of all modifications, when the zone is accumulated to a certain size, perhaps upper layer application is thought when needing to upgrade, the zone that is modified is sent to hardware OSD equipment, finish drawing.As shown in Figure 2.
Wherein, by standardized requirement, all mapping operations all are designed to the mode at buffer operation, change development platform mapping operation is had no effect.Because the same hardware at a slow speed of mapping operation is separated, accelerate mapping operation simultaneously, shortened the drawing overhead time of using.
In sum, the present invention has realized following several big functions:
1. support by FrameBuffer equipment in the linux kernel, make the man-machine interface exploitation break away from hardware platform.
2. specially at television set OSD design one cover local updating mechanism at a slow speed.
3. the OSD memory copying mechanism of design standard set Frame Buffer-＞is at a slow speed transplanted fast to realize the exploitation back.
On certain high-end LCD TV, adopted this way, realized the exploitation experiment of TV menu, PVR (individual video recorder) menu, prove that this method can reach above-mentioned beneficial effect.
