Digital figure automobile instrument

[0032] Example 1:

[0033] (1) Overall composition:

[0034] See figure 1 , A digital graphical automobile instrument, including a processor 1, a memory 2, a parameter acquisition module 3, a display drive module 4, a display panel 5, and software, namely functional modules stored in the memory, wherein:

[0035] Processor 1: Use low-power, 32-bit or more than 32-bit embedded processor with real-time interrupt function (the processor is the core of the digital graphical car instrument, it will affect every aspect of the entire design, choose A good processor is very important. You must choose a processor that meets the design requirements in all aspects. Under normal circumstances, do not choose a processor lower than 32 bits);

[0036] Memory 2: Including RAM and ROM. ROM is used to store software and data, that is, to store functional modules. The most suitable type of ROM (including ordinary ROM, EEPROM, Flash Memory, etc.) should be selected according to the purpose of the store

[0066] Example 2:

[0067] This implementation mode adds user input buttons 6 and sound output drive module 7 on the basis of Example 1, and adds an interrupt handler module (processing user input data) and a graphics selection program module (such this digital graphics A variety of display graphics can be stored in a car instrument).

[0068] (1) Overall composition:

[0069] See image 3 , Including the processor 1, the memory 2, the parameter collection module 3, the display drive module 4, the display panel 5, the user input buttons 6, the sound drive module 7, and software, namely the functional modules stored in the memory, in which:

[0070] User input button 6: used for user input data;

[0071] Sound driver module 7: sound output, including alarm sound, etc.;

[0072] The functional modules stored in the memory are the required software: including the parameter sampling program module, the dynamic graphic construction program module, the graphic combination program module, t
