I have been following the "Simple Installation Process" in the Pi Co-op manual to setup a working Raspberry Pi system. I am using a 32GB SD card setup with NOOBS 1.3.5 (ie. Raspbian 7.5), installed Arduino IDE version 1.0.1. I have selected the "blink" sketch and tried to upload it to the Pi_Co-op board, however I get the error message:-

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
Binary sketch size: 1,072 bytes (of a 32,256 byte maximum)
done with autoreset
avrdude-original: stk500_recv(): programmer is not responding


I then pressed the reset button on the Pi_Co-op board (as suggested by the Trouble shooting guide); I then edited the Blink sketch to write to the Serial Monitor and uploaded this modified version only to get this message:-

Binary sketch size: 2,432 bytes (of a 32,256 byte maximum)
/usr/bin/autoreset:21: RuntimeWarning: This channel is already in use, continuing anyway. Use GPIO.setwarnings(False) to disable warnings.
GPIO.setup( pin, GPIO.OUT )
done with autoreset


The messages sent to the Serial Monitor are being displayed.

Any suggestions on how to fix these errors?

Hi there,

The first warning seems to be an occasional bug which I think is due to a timing issue when sending a reset to the Pi Co-op. Please let me know if you see it a lot.

The second warning is fairly harmless (at this point the blink sketch should have been uploaded, did you see this?). The warning happens because there wasn't a call to GPIO cleanup at the end of the auto reset script. I've uploaded a fix to try and get rid of this warning, if you've got the time, could you please try it by running

Code: Select all

cd pi_co-op
git pull
sudo python  setup_pi_co-op.py uninstall
sudo python  setup_pi_co-op.py install

Regards

Hello Alan,

Thank you for your response.

I'll keep an eye out for the re-appearence of the first warning.

I have installed your modified software as suggested, and I now do not see the second warning.

Perhaps the Pi Co-op manual should be modified to say that after a sketch is uploaded expect to see the message "done with autoreset".

I'll now try and get my head arround using "Firmata".

This board is certainly a lot easier to setup and use when compared with the GertDuino.

regards Galen
