Look at the diagram: you obviously need a 1-second "clock" that controls everything; then you just need to count the clock "ticks" and toggle each pin on the appropriate count... I used Timer0 for 1sec delay and with that i can toggle P1.0 for each overflow. But i could not do the same for other ports. this is the problem i face. I tried incrementing a register for 1sec delay and toggling the ports by reading it. But couldnt find a suitable Solution. Erik, Thanks for that link on PCA. But as the rating says its really a homework assignment given to me by an employer. I was told to develop a ASM code for it. regard's Suresh. |
