Help to develop software for freq. counter

[szabi]

I understand now, nice procedure. You should get now a 10Hz resolution?
Why are you inverting twice the value in prescaler? ~(256-count)

I have found another good counter, that uses the same technique:

szabi,

(256-count) - this is just result of count up procedure. After that we need to restore the byte value. The byte value = ~ count up +1.

Assembly code of 2.5GHz counter using LMX2322 and PIC16F870

Dear All
I have the complete assembly code of 2.5GHz Freq Counter with
"7-segment displays",
Link for complete project site, the auther of this site is very intelligent person
and this is the best site ever seen for RF Hobbiests.
2.5 GHz Frequency counter
interested persons can contact me through the following email.
kamranmu@yahoo.com,
Actually I have disassembled and done some modifications, and when compiled it using MPLAB, now surprisingly the compiled code (HEX Format) is 100.00% same to the original code given at the project site. but there are very minimal charges for this code.

OK
