2、gn take AT89C2051 as the core, making use of the operation of a machine and controlling the function, the E2PROM saves the data, and adopt a LCD manifestation mold piece actually the hour show that design the project the speed table of distance of measure the speed and mileage. This thesis divides t
3、he stanza of a cent, distinguish from the design the principle project, design the function realization, the function adjusts etc. for try many the angle carries on the detailed analysis; Take into the introduction to the function of each parts of mold piece also; The appendix related data and pictu
4、res, strive for the precision to give to the last man with the process and the result of display the design. That project because of using a LCD manifestation mold piece and E2PROMs, and efficiently fast calculate way, as a result for economize the system resources and simplify the program design to provide the beneficial premise and foundations.
