    Default syntax error

    Hi,

    I'm trying to use 4 pots to provide a range of values to set the temperature set point in the code featured http://www.picbasic.co.uk/forum/showthread.php?t=12712

    When I use the following code I get a bad expression syntax error on the SetPoint(ADchan) = POTS(ADchan) line

    Code:
        FOR ADchan = 0 to 3
        GOSUB GetADC
        POTS(ADchan) = ADvalue
        SetPoint(ADchan) = POTS(ADchan)
    NEXT ADchan
    My logic seems that it gets the adc value, places that in the POTS(0), POTS(1) etc, and then should give SetPoint(0) the same value as POTS(0)

    All I really need is a range between 100 and 500 for each SetPoint

    Have you tried [square] brackets ?
    If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.
    .
    Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants - but debt is the money of slaves

    Hmmm . . . so (ADchan) is a MATH operation ? I thought it was an array, if it is, then (brackets) are OK ?

    Hi Malc, I would say pretty darn easy, given the size of this program, I just un zipped it, nice work ! To all involved.

    Thanks, but really the credit for the coding goes to Darrel.

    I'm still a rookie in PBP, and it's taking me hours to try and work this out and I'm still having trouble getting the value from the pot to change the set temperature
