Hi
I have initially mentioned my two issues related to frequency counter in this thread.
As the second issues mentioned in that thread was separate from the thread title, I have created this second thread.
Here I have taken example of frequency counter suggested in this thread:
and modified it. Please see attached project and Picture file 4.jpg. See the path for “Freq_Clock” and see the attached picture and this are three cases:
Case 1)
RPM frequency is generated 12 KHz, Routed to PIN P0[6], through a external wire(jumper) connected to PIN P0[2]. Result: working fine
Case 2)
RPM frequency is generated 15 KHz, Routed to PIN P0[6], through a external wire(jumper) connected to PIN P0[2]. Result: working not OK.
Case 3)
RPM frequency is generated 15 KHz, directly connected on schematic with Frequency Counter. Result: working not OK.

Hi,
I tested the project with external wire with 15 kHz input frequency. It measures correctly. Can you check if wire was properly connected ?
Also, I noticed that you have double sync enabled on input pin. Disable the double sync on input pin "Freq_In" as it syncs input signal with master clock twice. You are anyways syncing input later in the schematic. I have attached an image showing how to disable double sync.
Thank you,
Pavan
