Description
?
Technical field
The present invention relates to a kind of display screen devices at full hardware control system of simple general use, relate in particular to a kind of technology of dot matrix display screen control, belong to field of intelligent control technology.
Background technology
Universal day by day along with computing machine, more and more important with the computer controlled information promulgating platform that is made as the basis.And the control system of digital dot matrix display screen changes along with user's request always, waste of manpower and material resources.For addressing this problem, need general devices at full hardware control system of design.
Summary of the invention
The purpose of this invention is to provide a kind of general, simple and convenient, devices at full hardware display screen control system, this system can meet customer need easily and effectively.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of display screen devices at full hardware control system of simple general use is characterized in that: this system comprises CPU control module, memory module, signal controlling module, row modeling piece, LED lattice module, and changes the string module and a plurality of string changes and module; Said memory module respectively with CPU control module, signal controlling module and and change the string module data and be connected; Control end said and commentaries on classics string module and row modeling piece links to each other with the signal controlling module respectively; And commentaries on classics string module links to each other with row modeling piece; Said a plurality of string changes and module is dot matrix and arranges and is connected with row modeling piece, and the string that dot matrix is arranged changes and module correspondence connection LED lattice module.
Wherein also change the string module and adopt chip into 74LS165; String changes and module adopts the 74LS164 chip; Memory module adopts RAM or EEROM storer.The signal controlling module is made up of the addition chip; Row modeling piece is that multichannel selects chip to form.
The present invention compared with prior art has following advantage:
The display screen devices at full hardware control system of a kind of simple general use of the present invention's design according to the hardware control circuit that invention is designed, is read the data in the memory module, controls the demonstration on the LED dot matrix screen with the mode of dot matrix.In reading memory module during data earlier through and change the string module and become serial data to data-switching; Send to certain delegation of dot matrix screen through the control of row modeling piece; The row of dot matrix screen show to be realized through serial-shift; After data shift satisfied delegation, changeing also through string, module upward showed data latching to the dot matrix screen.All timing control signals are generated by the signal controlling modular circuit.
The present invention is that devices at full hardware realizes, the height that real-time realizes than software, and independence is good, does not take the CPU time of custom system, and is with low cost.
When LED dot matrix size changes, need not to adjust main control circuit part (comprise memory module, signal controlling module, and change string module and row modeling piece), only needing to change string changes and lattice module.
When LED dot matrix resolution changing, need not to adjust main control circuit part (comprise memory module, signal controlling module, and change string module and row modeling piece), only need also to change that the apolegamy string changes and the quantity of lattice module.
The user, just can show after powering on as long as wanting data presented to deliver to the respective regions of memory module, connect the dot matrix panel module more automatically.
Progressive also is, and: CPU just can show as long as deposit video data in respective stored module space automatically, need not take the CPU time completion and show.
As long as change the locus that video data is deposited.
Total system of the present invention adopts simple digital circuitry module to realize, and is cheap.Software control is not used in devices at full hardware control, and extensibility is good, and versatility is good, and the hardware line is few, and the demonstration real-time is good, and final the demonstration is to adopt static demonstration, and brightness can guarantee.
Description of drawings
Fig. 1 is the display screen devices at full hardware control system structural drawing of simple general use.
Embodiment
