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?
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.
Regards
Sven
