Problems solved by technology
At present, most of the instrument development process adopts this scheme. Compared with the first scheme, this scheme greatly reduces the number of image resources, thereby reducing the resource memory usage, but the control strategy is very complicated, and the coordinates of different states need to be calculated. When using the formula to calculate, there will be a situation where the coordinates of the special state cannot be one-to-one correspondence. It is mandatory to set the coordinates of the pointer and the scale to correspond one-to-one, which requires a lot of calculations and tests, which greatly affects the accuracy of the instrument and the design time.

The invention discloses a pointer design method of a liquid crystal instrument. The method comprises steps of importing the picture resources corresponding to the plurality of groups of pointers and scales into a CGI studio system; the pointer and the scale are subjected to coordinate design in the CGI studio system; coordinates are generated in the CGI studio system, and the coordinates are stored in the CGI studio system; a txt file of the precision interval and the appointed address is imported into a Capiciron platform; A pointer deflection algorithm in a txt file is used for replacing anoriginal algorithm in a Copicorn platform, then a Bin file for controlling a pointer is exported from the Copicorn platform, and the Bin file is imported into an instrument to achieve strong rotationof the pointer. According to the invention, the occupied instrument memory is greatly saved, the design difficulty of the pointer is greatly reduced, and the precision of the instrument is effectivelyimproved.
Description
technical field [0001] The invention relates to the field of automobile instrument design. More specifically, the present invention relates to a pointer design method of a liquid crystal meter. Background technique [0002] Automotive instrumentation provides drivers with important information about the vehicle. With the development of embedded technology, the instrument is updated faster and faster; at the same time, the rise of smart cockpit and driverless technology requires the instrument to provide higher sensitivity and accuracy. . People have higher and higher requirements for the accuracy of the instrument, but the current design method of the pointer of the liquid crystal meter is relatively backward, not only the accuracy is low, but the design method is also too complicated, so it is necessary to develop a new pointer design method to provide higher accuracy of the meter pointer . [0003] CGI studio Studio is an upgradeable software platform that is not limite...
