Bus Pirate Support / BP I2C Drive Strength?
I was wondering if anybody knows how much drive strength (current) that the I2C line outputs?  Is it a configurable parameter that can be changed?  From the provided menu that did not seem to be the case.

Bus Pirate Development / BP v3 I2C 16-bit register writes?
I have a component that uses a 16-bit register write, and I'm a bit unsure if the BP is writing and reading correctly.

Does this look correct? (from a terminal session)  There doesn't look like there's any distinction when I write a 0x000A or a 0x010A. 

I2C>[0x34 0x000A 0x47 0x81]
I2C START BIT
WRITE: 0x34 NACK
WRITE: 0x0A NACK
WRITE: 0x47 NACK
WRITE: 0x81 NACK
I2C STOP BIT
I2C>[0x34 0x010a 0x47 0x81]
I2C START BIT
WRITE: 0x34 NACK
WRITE: 0x0A NACK
WRITE: 0x47 NACK
WRITE: 0x81 NACK
I2C STOP BIT
