      Hi, todat I opened a new project, I wanted to have a timer running free on  my project so I can need to get delta time, the thing is that I start the timer and it it counting backwards?? , how can I fix this?, It can not be a software Error, because I am Only calling Timer_Start(); and Timer_ReadCounter();

         

      Thanks =)

          Welcome in the forum.

             

          The timer usually counts down to zero from period value. A simple difference (PeriodValue - Counter) will give the counts elapsed.

             

          Some more information needed: Which PSoC ? Which board (self made, Kit? Which kit).

             

          When you got stuck, please post your complete project, so that we all can have a look at all of your settings. To do so, use
          Creator->File->Create Workspace Bundle (minimal)
          and attach the resulting file.

            Great, this is what I did:

               

                    uint8_t a = Timer_ReadPeriod();

               

                    uint8_t b = Timer_ReadCounter();

               

                    CurrentTime = (a - b);

               

             

               

            Im Using CY8CKIT - 059 , the project is really simple, im just trying to check for Delta time so I can read it at the begin of my loop and then use the same "time" on different functions, I think it was a pretty generic project so i didn't included it, but got it gorking now, thanks Bob
