    PSOC3 counter difficulty

    telemaque.olivier

      Hello,

         

      I use a "Up and Down" counter ( 32 bits ) configured as follows :

         

      -period : 4294967295 (2^32  - 1)

         

      -clock mode : count input and direction

         

      -run mode : continuous

         

      -reload counter on "reset" and on "tc"

         

      Besides my input pin is configured in "resistive pull down" as drive mode, my goal is to count rising edge of a rotary encoder (in order to know the position of a robot), however my problem is when I turn my encoder the counter increment too fast whereas I turn a little bit the encoder. What's the problem ?

         

      Thanks.

         

      PS : I'm French what explain the quality of my English, I joined the project with the post, the name of the counter is "Counter_debug" in the PSOC Creator project!
