I2C Resource Busy

Taylor Howard

If I use i2cget to read a byte from a connected I2C device I get:

root@Omega-0849:~# i2cget -y 0 0x10 0x00
Error: Could not set address to 0x10: Resource busy

If I use the force option I can successfully read a byte:

root@Omega-0849:~# i2cget -y -f 0 0x10 0x00
0x54

Also when using the python onionI2C module I'm receiving an error:

root@Omega-0849:~# python test.py 
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Traceback (most recent call last):
  File "test.py", line 4, in <module>
    readVal = i2c.readBytes(0x10, 0x00, 1)
IOError: I2C transaction failed.

This is my Python code:

from OmegaExpansion import onionI2C

i2c = onionI2C.OnionI2C()
readVal = i2c.readBytes(0x10, 0x00, 1)
print readVal

Any idea why this would be happening?
