unable to find a 15-bit Binary Divider

[Lac]

I'm not able to find a 15-bit binary divider only 14-bit ones. Anyone know a way to make a 15-bit divider?

Thanks!
Lac.

:shock:

Sorry for being stupid..... but do you just want to rotate 2bytes right by 15 bits?

 

[Lac]

huh?

What I really want to is to divide the 32 KHz clock signal from an oscillator down to a 1Hz signal.

A frequency devider is really just a digital counter. If you take your 14 bit devider, put a 4 bit counter on the output and just ignore the extra 3 bits.

Try this.
32768kHz on the input. 1Hz on the output.

csaba911, aint that two 12-Stage binary counters you have used there?

csaba911:

Should'nt the second stage binary counter be 3-bits only???...if you want to get 1Hz.

 

[bmcculla]

By taking the output from the 3rd bit you ignore the other 9 bits so it works like a 3 bit counter.

YES

and you are right !
Q2 have the 1Hz clock output.

:?:
Is this 1hz clock to be used in some pic code or do u just want a 1hz clk availble on the pcb?

 

[Lac]

it's a 1hz clock that is going to be used in a digital clock.

:shock:

Sorry, it's probably me....... :wink: but are you going to use a pic to display the digits etc? It's just that the post is in the microcontroller section, I thought you may be after some help with a micro-based clock.

Again sorry if I have got the wrong end of the stick :wink:

My fault.. I saw that i had posted it in the wrong section, but then it was too late. But anyways, thanks for help! :wink:

Cheers!
