I have been scratching my head to work out a routine that would return
true if the result from an AD conversion is within a certain range.
For example
if ADRES >= 40 and ADRES <=60 then Interval = 5000
else Interval = 1200
Most things that seem logical fail.
Any help/suggestions would greatly appreciated.
Well, in the first place: assuming you are using the Jallib ADC library
- why would you place your message here otherwise - you have nothing to
to with ADRES. The ADC value is returned by the functions
adc_read_high_res (a word) or adc_read_low_res (a byte).
When you have setup the ADC library correctly and low resolution is
sufficient for you and you are using pin_AN0 then you might read the ADC
value with:
var byte adcvalue
adcvalue = adc_read_low_res(0)
Now if you want to check if this value is between 40 and 60 (inclusive)
you could write:
if adcvalue >= 40 & adcvalue <= 60 then
Interval = 5000
end if
Note: the word 'and' is not a valid operator in JAL. Check section 3.1
of the jalv2 manual for a list of operators with JalV2
