The Design of LED Rolling Characters Display Based
on SCM
Abstract:This design in view of thepresent LED display monitor, in
national dividend’s many domains obtain in the widespread quotation
situation, has carried on this paper design after the investigation.
This article introducesthe design of Chinese scroll screen with 16 x
16 lattice LED based on monolithic AT89C51. And it
emphaticallyintroduced the LED lattice demonstration hardware design
mentality, hardware circuit each part of functions and the principle,
the corresponding software’s programming emphatically, as well as
detailed operating instructions and work flow.
This design divides into six parts, the primary coverage is the
system macro analysis, the system hardware design , the system
software designs three parts. The system macro analysis is this
article foundation, the system hardware design is this article key,
is this design hard core, this part first simply describes the system
hardware principle of work, and attaches by the system hardware
design diagram, elaborated various hardware interface technology
which and each interface module function and the work process this
graduation project applies. The system software design is this
article sublimation.
This article composes the guiding ideology is the software and
hardware unifies, take the hardware as the foundation, carries on
various functional module the design. This design usability is strong,
simplicity of operator, extended function.
