Question about RPS.

I am looking to write the following code, however I am stuck.· I know you guys will beat it out in second, so I figgured I would ask.

I have a switch, I need to measure how many times a second the switch is being activated. But it needs to have 2 different levels.

If the switch is activating 1· - 6 times a second I need to set a variable to 1
If the switch is activating 7+ times a second I need to set a variable to 3

However it needs to constantally monitor the switches/second.· If it drops under 7 it needs to change the var to 1, if it goes above 7 it needs to change the var to 3

The variable will be used in a loop to control the number of times a solenoid is activated.

Thanks,
·· Chris

    Give this a go:

    COUNT switch, 1000, swIns
IF (swIns > 6) THEN 
  rate = 3
ELSE
  rate = 1
ENDIF

    Jon,
    ·· Will that freeze the program for the entire second?

    I am also working on a switch / solenoid program.· Every time the switch is pulled I need it to activate the·solenoid 1 time, however if the switch is pulled more then·7 times a second I want it to activate 3·times for every pull.· The·switch and the pull need to operate·together.

    The variable controls how many times the·"Activate" routine activates inside of a loop.

    Thanks
    ·· Chris·

    I'm not even sure Miss Cleo could help here.... but let me keep trying.

    Can one measure the time between one trigger pull and the next, then work from there? -- assuming that the trigger pulls are going to be at a fairly regular rate.· If the trigger pulls are about 142 ms or less apart, that would be seven pulls per second.

    GOSUB Reset_Timer
DO
  GOSUB Wait_For_Trigger
  GOSUB Get_Timer
  GOSUB Reset_Timer
  IF (timer > 142) THEN
    rate = 3
  ELSE
    rate = 1
  ENDIF
LOOP
