I2C Resource Busy
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
onionI2Cmodule 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?
