Abstract

A panel adjustment method is executed on a host to adjust settings of a panel connected to the host through a serial bus. The method determines whether the panel is supported by the host. When the panel is supported by the host, the settings of the panel is read from a database of the host to accordingly set the panel. It is further determined whether the panel is correctly set or not. When the panel is correctly set, it is further determined whether the panel is of a frame buffer mode or not. When the panel is of a frame buffer mode, it is determined whether a header file generation is required or not. When the header file generation is required, the settings and a panel name are included in an include file. The include file is compiled to thereby generate a binary file which is loaded into the panel.

Claims

1. A panel adjustment method, which is executed on a host to adjust settings of a panel connected to the host through a serial bus, the method comprising the steps of:

(A) determining whether the panel is supported by the host;

(B) reading the settings of the panel from database of the host to accordingly set the panel when the panel is supported by the host, and further determining whether the panel is correctly set;

(C) determining whether the panel is at a frame buffer mode when the panel is correctly set;

(D) determining whether generating a header file is required when the panel is at a frame buffer mode;

(E) inputting an include file and a panel name, placing the settings and the panel name in the include file and storing the include file when generating the header file is required; and

(F) compiling the include file to thereby generate a binary file, and loading the binary file into the panel.

2. The method as claimed in claim 1, further comprising the step of (G) loading the settings into the panel when step (D) determines that generating the header file is not required.

3. The method as claimed in claim 2, further comprising the steps of:

(H) computing the settings of the panel when step (C) determines that the panel is at a bypass mode;

(I) selecting a bypass table file;

(J) determining whether the bypass table file contains a setting field for the panel; and

(K) using the settings of the panel computed in step (H) to update the setting filed of the bypass table file when the bypass table file contains the setting field for the panel, and executing step (F).

4. The method as claimed in claim 3, further comprising the step of:

(L) adding an associated field for using the settings of the panel computed in step (H) to update the associated filed of the bypass table file when the bypass table file does not contain the setting field for the panel, and executing step (F).

5. The method as claimed in claim 4, further comprising the step of:

(M) inputting the settings of the panel when step (A) determines that the panel is not supported by the host.

6. The method as claimed in claim 5, further comprising the step of:

(N) inputting the settings of the panel when step (B) determines that the panel is not correctly set, and executing step (C).

7. The method as claimed in claim 6, wherein step (C) is based on memory size of the panel to determine whether the panel is at the frame buffer mode.

8. The method as claimed in claim 7, wherein the panel is determined to be at the frame buffer mode when the memory size of the panel is greater than a threshold, and conversely the panel is at the bypass mode.

9. The method as claimed in claim 8, wherein the include file in step (E) has a filename extension “

.h”

.

10. The method as claimed in claim 9, wherein the bypass table file has a filename extension “

.h”

.

11. A computer readable recording medium, which loads a program for execution on a host to adjust settings of a panel connected to the host through a serial bus, the program comprising:

a first procedure, which determines whether the panel is supported by the host;

a second procedure, which reads the settings of the panel from database of the host to accordingly set the panel when the panel is supported by the host, and further determines whether the panel is correctly set;

a third procedure, which determines whether the panel is at a frame buffer mode when the panel is correctly set;

a fourth procedure, which determines whether generating a header file is required when the panel is at the frame buffer mode;

a fifth procedure, which places the settings and a panel name in an include file and stores the include file when generating the header file is required; and

a sixth procedure, which compiles the include file to thereby generate a binary file, and loads the binary file into the panel.

12. The computer readable medium as claimed in claim 11, further comprising:

a seventh procedure, which loads the settings into the panel when the fourth procedure determines that generating the header file is not required.

13. The computer readable medium as claimed in claim 12, further comprising:

an eighth procedure, which computes the settings of the panel when the third procedure determines that the panel is at a bypass mode;

a ninth procedure, which selects a bypass table file;

a tenth procedure, which determines whether the bypass table file contains a setting field for the panel; and

an eleventh procedure, which uses the settings of the panel computed in the eighth procedure to update the setting filed of the bypass, table file when the bypass table file contains the setting field for the panel, and executes the sixth procedure.

14. The computer readable medium as claimed in claim 13, further comprising:

a twelfth procedure, which adds an associated field for using the settings of the panel computed to update the associated filed of the bypass table file when the bypass table file does not contain the setting field for the panel, and executes the sixth procedure.

15. The computer readable medium as claimed in claim 14, further comprising:

a thirteenth procedure, which inputs the settings of the panel when the first procedure determines that the panel is not supported by the host, and executes the third procedure.

16. The computer readable medium as claimed in claim 15, further comprising:

a fourteenth procedure, which inputs the settings of the panel when the second procedure determines that the panel is not correctly set, and executes the third procedure.

17. The computer readable medium as claimed in claim 16, wherein the third procedure is based on memory size of the panel to determine whether the panel is at the frame buffer mode.

18. The computer readable medium as claimed in claim 17, wherein the panel is determined to be at the frame buffer mode when the memory size of the panel is greater than a threshold, and conversely the panel is at the bypass mode.

19. The computer readable medium as claimed in claim 18, wherein the include file in the fifth procedure has a filename extension “

.h”

.

20. The computer readable medium as claimed in claim 19, wherein the bypass table file in the ninth procedure has a filename extension “

.h”

.
