  1. 實例演練(4-6-1) • 連接電路 4ms 4ms 4ms

  2. Ch4-1.asm-1 ORG 0 ;程式從0位址開始 START: MOV P1, #1EH ;將最右邊數字顯示1 CALL DELAY ;延遲4ms MOV P1, #5DH ;將右邊第二個數字顯示5 CALL DELAY ;延遲4ms MOV P1, #0BH ;將右邊第三個數字顯示0 CALL DELAY ;延遲4ms MOV P1, #87H ;將最左邊數字顯示8 CALL DELAY ;延遲4ms JMP START ;從頭開始掃瞄

  3. Ch4-1.asm-2 ;=========延遲約4ms=(即2usxR7xR7)============= DELAY: MOV R7, #10 D1: MOV R6, #200 DJNZ R6, $ ; (2 machine cycles) DJNZ R7, D1 RET END Note: For XTAL clk =12 MHz, 1mc = 12 clk = 1μs.
