hi,henric thanks for replying ,i tried ur programm but its not working ,i guess i could not describe my requirement clearly,let me explain again ,
here i have this simple led blink programm and in this program led on portb.7 is blinking endlessly with the pause of 500ms
now i want another led to blink on portb.6 with pause of 1000 ms ,along with the led which is already blinking with pause of 500ms on portb.7 , both led on portb.6 and portb.7 should blink endlessly but different speed.
I dont need this programm in any project i am just trying to learn ,Thankyou ,i hope now i have made my requirement clear
