假定8051单片机P1端口外接矩阵式键盘,矩阵式键盘的列线(Y0-Y3)姐单片机P1.0-P1.3,而行线(X0-X3)接P1.4-P1.7。P2.0接发光二极管。根据键值的大小使发光二极管闪烁相应的次数。-
8051 P1 port assumed external matrix keyboard, matrix keyboard column line (Y0-Y3) sister SCM P1.0-P1.3, while southbound (X0-X3) received P1.4-P1.7. P2.0 connected light-emitting diodes. According to the size of the key to make the appropriate number of LED flashes.
