AbstractScreen control system including input interface circuit, signal control, transform processing circuit, cascade expansion circuit and output interface circuit to the specific technology, involving many
Often used MCS - 51 series microcontroller control, the design USES is STC12C5A60S2 chip control, technology applications, better at 51 series technology now hardware development is also very fast, also appeared many function very powerful microcontroller, so using SCM can realize the basic function requirement
Unit screen can receive from controller (master control circuit board) or higher level display element module transmission of data information and order down information, and can put these data information and order information without any change to teleport to next level aga
