Hi
Anyone can help about the following task.
Have to multiply input frequency by 11.
The input frequency range is from 1 Hz to 1 MHz.
Output frequency has to be from 11 Hz to 11 Mhz.
Input frequency is coming in time frames of 5 minutes to PIC input stochastically.Means for instance first freq. is 1 KHz and lasts for 5 minutes, after that come second freq. for instance 2 KHz which lasts 5 minutes, then come third freq. 950 KHz etc. etc.
That means first PIC have to measure input frequency, recognize if it has changed to the new value, and sent to output the present frequency multiplied by 11.
Much gratefull for any suggestion of which PIC to use for that and how to solve the problem. (16F628A with 20 MHz resonator, PIC16F1455 with 48 MHz osc., PIC18F13K22 with 64 MHz osc. ) ?
If you can post some code for that the better.
Have PBP3 Gold edition.
Thanks
