The Research on the Algorithm of Lattice LCD Drawing Controlled by PIC

With the instruments become more and more intelligent, multifunctional, the pointer display way can not meet this kind of development. LCD, especially the lattice LCD with great display screen makes it possible to produce instruments with much more beautiful interface and much more information on the display screen. In this paper some algorithms on drawing dot, line, circle, and the averagely partition of circle are introduced, which fit the applications of MCU. The actual application proves that these algorithms work well in the MCU applications. They can draw all the pictures that are needed for the instruments.
