Re: pyb.I2C.SLAVE can't discover.

I2C design to 2-wire, I'm curious how to test when writing this docutment:
http://docs.micropython.org/en/latest/l ... b.I2C.html
;)

What's purpose of pyb.I2C.SLAVE ?
And the pyb.I2C() big different between machine.I2C().

What's mean 'opt=3' in manifest.py for frozen ?

In some manifest.py file, likes:

Code: Select all

    "..",
    (
        "xx/xxx.py",
        ...
    ),
    opt=3,
)
What's mean

Code: Select all

opt=3

pyb.I2C.SLAVE can't discover.

I create a I2C slave via:

Code: Select all

i2c = pyb.I2C(1, pyb.I2C.SLAVE, addr = 0x43)
then connect PB6(scl), PB7(sda), GND to other board, but i2c scan result is empty on other board, and I try to connect it to RPi's I2C also.

What step I missing ?
