Adc Disconnecting Ezb

would appreciate assistance please
included a short set of instructions that reads a potentiometer on a motor shaft
and then moves a motor forward & reverse
but for some reason it crashes my EZB after a few moves

script
:one
set(d22, on)
ADC_Wait(ADC7, lower, 120)
set(d22, off)
sleep(900)
set(d23, on)
ADC_Wait(ADC7, higher, 180)
set(d23, off)
sleep(900)
goto(one)

Sounding like a broken record but, what is your power source? Most of these issues are from a servo using more power than can be supplied by the battery.
Ireland
#2  
don't think its a power issue
EZB has seperate 8.7v 1.5amp supply

one ADC input and two digital outputs used on EZB
think its something to do with script
#3  
Try using repeatuntil or repeatwhile as a loop instead.... It may not make sense, but try it...

It still might be a power issue, though
United Kingdom
#4  
The script looks fine. Check your circuit
Ireland
#5  
Using hbridge

8.7V 1.5amp supply to Ezb
5v supply to motor

d22 to in1
d23 to in2
gnd to gnd
adc7 to potentiometer

The resistance of the potentiometer is 4k7 is it possible that may be too low
Ireland
#6  
Disconnected everything from EZB except adc7 ran script and it disconnected
EZB after approx 1 minute
#7  
Do you know the actual ADC values present when you read ADC7? Try printing the value out and see what it shows.
#8  
The analog port's on the EZB4 voltage level is only 3.3v.. So If you are powering the pot from the analog ports are you sure the pot will work with 3.3V?

It has to be something along that line as with only the ADC port connected it will crash out
will do some further tests when I get home later
thanks

Thanks to all
did a full re install of EZ Builder seems to have resolved issue
well it has worked for more than a few minutes so fingers crossed

At times like this I need a resolved by " all " option
