Frequency counter using PIC's

I came across some good ideas for frequency counter using PIC's. PIC are now being available in India and hence these ideas can be tried out. In India 16C54 (OTP) and 16C84/16F84 are available. These are not my ideas and I claim no resonsibility of any kind towards it. .I have PCBs and the code required for this project, so if any of  you'll are interested in trying it out these project I can help them out.. The code for these counter are self explanatory on the various steps involved and one should check them out.
