This syste?m is compo?sed by on SCM small? syste?m and LCD displ?ay syste?m, on the PC machi?ne carri?es on the demon?strat?ion conte?nt the editi?on and matri?x data withd?rawin?g; LCD displ?ay syste?m contr?ols the modul?e and certa?in LCD by the host demon?strat?ed the modul?e T6963?C compo?ses, the host contr?ols the modul?e T6963?C to be respo?nsibl?e for in the recei?ve the SCM matri?x data and contr?ols each demon?strat?ion modul?e work, demon?strat?ed the modul?e take the host contr?ols the modul?e T6963?C as a core, contr?ols the LCD displ?ay monit?or displ?ay, In order? to the conve?nient? syste?m expan?ds, betwe?en vario?us modul?es conne?ction? uses meets? inser?ts the type struc?ture, betwe?en the SCM and PC machi?ne to use the RS-232 stand?ard to carry? on the data and the order? seria?l commu?nicat?ion. This artic?le not only has carri?ed on the whole? plan from the overa?ll to the syste?m, but also in detai?l intro?duced? take modul?e desig?n as the examp?le the PC machi?ne matri?x withd?raws, the matri?x data trans?missi?
