Using timer how to make 5 sec delay in pca10040 board?

[naveen]

Hi,

I am using pca10040 board. i need to toggle a led in 5sec once. I tried to change the prescale value. But im not able to get that much time delay.

Can any one help me on this?

BTW you can use TIMER to get 5 second delay. Using prescaler 9 and 32 bits the overflow value will be 2^32 / 16MHz * 2^9 = 137439 seconds.
