- RaspberryPi
- Running Rasbpian
- ssh raspberrypi.local
- Running Rasbpian
Steps Taken
- Installed Raspbian on a 16GB SD memory card
- Followed this guide to get I2C available
- Used this article to determine that I had a 256MB Model B RaspberryPi. This is important, because when checking i2cdetect I have to use "-y 0" instead of the "-y 1".
Troubleshooting
- Ran into this error when running DannyO's (hubcitylabs) poll.py script:
quick2wire/i2c.py", line 72, in transaction
ioctl(self.fd, I2C_RDWR, addressof(ioctl_arg))
