Accompanying drawing explanation
Fig. 1 is a kind of theory diagram of space pattern display device of capable of dynamic programming.
Embodiment
A space pattern display device for capable of dynamic programming,
LED stereo display array is by 512 5mm white led lamps pearls, 1 inch of built on stilts three-dimensional matrice that is welded into 8x8x8 of spacing, vertically the anodic bonding of each LED together, form row, at eight row composition one pages of same vertical plane, make row by a 74LS595 for every page and drive, have eight pages, eight 74LS595 have formed row driver element; LED stereo display array is divided into eight layers from top to bottom, and the negative electrode of the LED of every one deck links together, and forms a row, has eight row, is connected respectively to this eight row by eight Darlington transistors of ULN2803, forms row driver element.
Indicative control unit forms minimum system by single-chip microcomputer STC12C5AS60 serves as, and crystal selects 24MHz.The P0 mouth of STC12C5AS60, after 74LS373 expansion bus, forms in conjunction with P2 mouth, P3.6, P3.7 the complete bus structure that comprise 16 bit address buses, 8 bit data bus, read-write control line.High 3 at address bus connect a 74HC138 generation chip select pulse.Data bus P0 mouth is connected respectively to the data input pin of eight 74LS595, and the synchronous input end of eight 74LS595 connects together, and is driven by P3.5; The P1 mouth of STC12C5AS60 is connected respectively to the base stage of eight Darlington transistors of ULN2803.
Memory RAM is served as by two 62256, and every has the storage space of 32K; Be connected respectively in bus, by two output line gatings of 74LS138; Indicative control unit STC12C5AS60 first forms the data of the pattern of wish demonstration in 62256 according to directive script, then data scanning is outputed to row driving array, row driving array, the shown pattern of control LED stereo display array.With two 62256 make indicative control unit STC12C5AS60 can rotation output different pattern, to reach the effect of dynamic mapping style.
Storer EPROM is served as by a slice electricity erasable memorizer chip 27C512, is connected in bus, by an output line gating of 74HC138; It has the storage space of 64K byte, can store 1K preset pattern picture; Indicative control unit STC12C5AS60 can call these patterns as material, is written to the medium demonstration of sending to be scanned of RAM62256 after data processing.
