Re: Cloud robotics demo code (now with actual code and links to BBC and FT)

Hey everyone! I know I'm way late in this thread but I wanted to say I love what you all are doing. Sorry I haven't had more time on the forum here, but you all are doing an outstanding job running with this. Love it!

Re: Motor gearbox broken - part specs?

Great idea. I think that would need to be designed on a case-by-case basis. You can access the motor control signals with the port on the lower left corner of the main board. You'd probably want to use those signals to control an external motor driver with an external power system. I wouldn't pull p...

Re: Motor gearbox broken - part specs?

If anyone has a motor that never worked correctly, please let me know and I'll replace it. I've heard from 2 people who had this problem. If anyone else send me a contact form from the main website. If you need extras - we purchased them custom, but they are the same motor as this one from Pololu: h...

Re: volts.py output problem

You may still get a few errors here and there. I have seen those randomly in testing, but it shouldn't be a "lot" of errors. Also note that the Arduino can occasionally hang the bus (seems to have something to do with the bug on the Pi side) - I've only seen this hanging if I have comms fr...

Re: volts.py output problem

Yep. That's it!!!!!!!!!!!!!!!!!!!!!!!!!! :D :D :D Use the following command to edit your /boot/config.txt file: sudo nano /boot/config.txt Add the following line. (I added this right above the dtparam=i2c_arm=on line, but I don't think it matters where it goes) dtoverlay=i2c-bcm2708 sudo reboot Whe...

Re: volts.py output problem

FWIW the switch from the 2708 driver to the 2835 driver happened with the update to Raspbian 4.9, and I am hearing reports of similar issues with other programs. (Broadcom 2708 is the original chip used as the RPis CPU, and Broadcom 2835 is the same core but in a SOC which includes RAM as part of t...

Re: volts.py output problem

So for both my Pi's I need to have i2c_bcm2835 loaded for i2cdetect to run, but I think for your working unit Kevin you have i2c_bcm2708 loaded. Yea I'm thinking this may be it. How can we make 2835 not load at all, but instead load 2708? If we could try that and things work I would be very happy b...

Re: volts.py output problem

Thanks gpvillamil. I tried sudo modprobe i2c-bcm2708 after running the commands below and just tried volts again and it didn't work. I wonder if the other driver must be removed first? (the i2c_bcm2835). Here are the outputs requested.... lsmod Working Unit: Module Size Used by bnep 10336 2 hci_uart...

Re: volts.py output problem

Here are some differences between the working and non-working units. If you think anything else will be helpful, please post the exact command I should run and I'll post it up. dpkg-query -l | grep -i i2c output: Working Unit: ii i2c-tools 3.1.1+svn-2 armhf heterogeneous set of I2C tools for Linux i...
