OpenPin crashes if the pin is already exported #4

Closed tylerstillwater closed 11 years ago

Check to see if the pin is already exported before attempting to export.

weird, i thought I fixed that.

Was that a recent fix? It is possible I haven't pulled it. I'll double check.

I have the latest code and it is crashing if export is already done. This is a legit bug.

Cool. Thanks for checking. At the same time, please check too see if a pin which cannot be exported gives a sensible error. Some GPIO pins like GPIO 14,15, and 16 my be in use by the operating system. http://elinux.org/RPi_BCM2835_GPIOs.
