Abstract
A handheld diagnostic device and method for displaying bitmapped graphic characters is provided which utilizes a condensed bitmap library. In particular, the present invention provides a method for condensing extremely large graphically-based bitmapped character sets, such as Chinese, Japanese, Korean or any other graphically-based bitmapped character set, and storing them in simple and economical handheld automotive diagnostic devices.
Claims14
A method for displaying diagnostic trouble codes and affiliated definitions of the diagnostic trouble codes on a handheld electronic diagnostic device, the definitions comprising at least one language character derived from a bitmap which is configured to be displayed graphically, the method comprising:
- determining a desired language to be communicated via the diagnostic device;
- obtaining a library of bitmap fonts and affiliated identification codes representative of a comprehensive character set from the desired language;
- compiling a unique set of characters from the comprehensive character set that are to be displayed by the device;
- and
- generating a condensed library of bitmap fonts and affiliated identification codes representative of the unique character set;
- compiling a list of diagnostic trouble codes and affiliated definitions to be utilized by the device;
- and
- generating a composite code representative of each definition of each diagnostic trouble code, wherein each composite code is a compilation of the affiliated identification codes making up the definition of a respective diagnostic trouble code.
A handheld diagnostic device for receiving diagnostic trouble codes from an on-board vehicular computer, and displaying the retrieved diagnostic trouble codes and affiliated definitions, the definitions comprising at least one language character derived from a bitmap which is configured to be displayed graphically, the handheld diagnostic device comprising:
- a handheld device containing a central processor unit, ROM, SRAM, flash memory, an input port, keypad, and display;
- and
- a computer readable medium for displaying diagnostic trouble codes and affiliated definitions of the diagnostic trouble codes on said display, the computer readable medium comprising:
- a source code segment which provides a condensed library of bitmap fonts and affiliated identification codes representative of the unique character set selected from a comprehensive character set representative a language, wherein the unique set of characters are displayed by the device;
- and
- a source code segment which provides a list of diagnostic trouble codes and affiliated definitions to be utilized by the device;
- a source code segment for providing a composite code table comprising the list of the diagnostic trouble codes and respective composite codes representative of each definition of each diagnostic trouble code, wherein each composite code is a compilation of the affiliated identification codes making up the definition of a respective diagnostic trouble code.
