Wonderful,
dataFile reset.
^dataFile upToEnd
I thought every read request would just produce a new value.
Thanks,
Herbert
does the trick

Hi,
I can successfully read a GPIO Pin on the RasPi if I do it like:
|value|
dataFile ensureOpen.
value := dataFile upToEnd.
dataFile close.
^value
dataFile is the /sys/class/gpio/gpioxx/value file that exists
after exporting gpioxx.
Without the reopening and closing of the file I get '' on
subsequent reads which means that
StandartFileStream>>basicNext answers nil.
Is there a way to get the values without having to close and
reopen the file each time?
Thanks
Herbert
