Description

technical field [0001] The invention relates to a digital instrument, in particular to a construction machinery digital instrument based on LPC2478. Background technique [0002] The instrument system is an indispensable part of construction machinery. It can directly reflect the state information of the engine, chassis and other working devices during the operation of construction machinery. It is an important basis for the driver to obtain state information of construction machinery and correctly operate construction machinery. Thanks to the rapid development and popularization of modern sensing technology, microcomputer control technology and display technology, instrument technology is also developing to a higher level. The form of the instrument has developed from the original direct-reading type and pointer type to image display and digital display; from sound and light alarm to intelligent monitoring. At present, most construction machinery still uses traditional ste...
