Piface Digital 2 InterruptEnableException #24

Closed simonsmart99 closed 9 years ago

simonsmart99 commented 9 years ago

Hi all

I am VERY new to Raspberry pi and linux in general, so please excuse the noob questions.

I have followed the Piface Digital 2 installation instructions to the letter, however receive an interrupt error on line 213 of the Interrupts.py script when I try to run the blink.py script. I am using python 2 by default, but have tried to run the blink.py script under both python 2 and 3. I have attached response in both versions.

At first I thought the problem may relate to the SPI driver, but I have enabled the port and tested it by bridging the MOSI and MISO pins and running spidev_test.c. I receive the correct response.

python 2

start using python2

python 3

start using python3

Any help would be greatly appreciated. Kind regards Simon

Hi, there appears to be a bug with our interrupt exception handler in your example, however the root cause is actually to do with the software not finding the GPIO pins. If I remember correctly this was because they moved after a kernel update (or something like that). Anyway, all should be fixed now. Can you try updating with:

sudo apt-get update
sudo apt-get upgrade

to see if that fixes your issue?
