Source attached.

Functions are:
Frequency measurement up to 500MHz, in 2 ranges (:1 and :10) and with/without prescaler;
Period measurement down to 0.1Hz and up to 1uS;
IF (intermediate frequency) add/subtract feature, from 1 to 99999999Hz.

Using a PIC16F1847.

If disabled or set to 1:2, it does not go... Attachments: frequenz17.c (23.32 KB)
