LED control structure based on address code burning and reading

Abstract

An LED control structure based on address code burning and reading, comprising a control end and a plurality of display modules. The control end comprises a first instruction data interface, which is connected with a first processor, and the first processor is connected with an address code operation end. The display module comprises a second instruction data interface, which is connected with a second storage unit, a counter and a second processor, the second instruction data interfaces of the display modules are connected in parallel to the first instruction data interface, the second processor is further connected with an address code control inlet and an address code control outlet, the address code control inlet of the first display module is connected with the address code operation end, and the address code control inlets of the other display modules are respectively connected with the address code control outlet of the previous display module. The utility model can improve the reliability of the display system, the individual display module can still work normally when damaged, and the problematic display module can be conveniently checked out and replaced.
