Yet another I2C driver - with utilities

Erlend

Just had to make my own driver, bit-banging the protocol into my brain so that it sticks. Includes some utilities for scanning and re-addressing.
But why does it not show up when I do a Search on OBEX?

And your new SPI Driver is here:

I just sorted by posting date, and they all showed up.

Ok, thanks.

Sounds cool.
When posting a summary, you could include the Clock range supported, and if it is master, or slave, or both, and if it supports Clock Stretching.

Ok. Done.

That was quick

To check the speed of a master, you can capture time before/after some common sequence like Read 1 or 2 bytes from Serial EEPROM.

Repeat with differing pull-ups.
A pull-up of 1k is only 3.3mA of BUS current.
