08m2 frequency trip "please help"

#1
Hi,

Looking for simple program for a frequency trip using the 08m2 chip. i/p around 3 volts frequency range 0 - 3000 hz, trip setting example 1000 hz & 2000 hz.

Many thanks

Do repost it in the forum , as then many will see it and be able to help. Also, say a bit about what this is for, it is hard to respond to a simple problem statement like this.

At present I wish to make a simple ferquency trip, via a "magnetic pickup which gives 3 - 12 volts a.c. depending on the air gap" the project requires to sense around 0 - 500 r.p.m. & 2020 r.p.m as an example to disconnect the starter and then also shut down when overspeed reached.

I'M o.k. with the circuitry and can test using a square wave generator with i/p of say 3v as I have used 08m2 chips for many projects; it's just the simple programming I get stuck with for the correct instructions and read to P.C. Screen.

Hope this makes some sense.

Regards

Ron
