#38380 - Check my Delay Responding to: ???'s previous message |
Let say i have to make a program for an LED which is connected to P1.0 to blink it continuously..
1) Using 12 Mhz Crystal. Crystal/ 12 = 1 Mico-Second. Time of Delay / 1 Micro-second = 1000000 so i need 1000000 instructions to create 1 second delay. 2) It means that 100*100*100 = 1000000 MOV R0,#101 MOV R1,#101 DELAY1, MOV R3,#101 DJNZ R3,$ DJNZ R1,DELAY1 DJNZ R0,DELAY1 CPL P1.0 RET IS IT OK |
