Hi kodyaz!

Sorry for the long wait, I missed the post - sorry!!!

It looks like the module could not communicate with the piControl0 device.

Could you type this command to a linux shell and post the return value?

Code: Select all

ls -lah /dev/piControl0

Could you use your existing program c.py and extend it like this:

Code: Select all

import revpimodio2
rpi = revpimodio2.RevPiModIO(autorefresh=False)

print(rpi.length, rpi.procimg, rpi.configrsc)

# Do some things on the process image
print(rpi._myfh.tell())
print(rpi._myfh.seek(0))
print(rpi._myfh.read(1))

Please post the outputs including errors!


I will build an extended version of RevPiModIO with a "debugging" flag to show detailed error messages.
