i2c-tools userspace tools

[Svein Seldal <sveinse@seldal.com>]

Hi

Is this the right list to discuss the i2c-tools user space software? If 
not, please disregard this email.

I have noticed that I can't seem to be able to use these tools out of 
box for very many i2c devices, as the i2cget/i2cset isn't using a very 
common protocol that these chips use.

E.g. the protocol for byte/word read (which is also found in the SMBUS 
spec) is:

START - WR:SLAVE - DADR - START - RD:SLAVE - DATA - STOP

 From what I have tested, it seems "i2cget BUS SLAVE DADR" does the 
following

START - WR:SLAVE - DADR - START - RD:SLAVE - DADR - DATA - STOP

It contains an extra read DADR byte, which is the slot where the actual 
data is being returned.

(My workaround is to run "i2cset BUS SLAVE CMD; i2cget BUS SLAVE")

Is this something that patches will be accepted for?


Best regards,
