    PSoC 5 Frequency Counter, Problem when routing Clock Externally

    user_202683688
          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.
