Q: I2C on Nucleo F401

Post by ubiq_01 » Mon Feb 08, 2016 1:51 pm

Is there anybody actively using the Nucleo MicroPython port? I'm using the nuraci source tree refered to from
https://github.com/micropython/micropyt ... LEO-F401RE and that works well in general. I have trouble
using the I2C functionality though. Specific questions are:
Which pins to use (I use PB8/PB9 on the Arduino header)?
Any specific additional initialization needed? (i2c.scan() doesn't find a peripheral, whereas it does with the same one on the pyboard)

I'd also be interested in getting into direct email interaction with the developer(s)/user(s) of the Nucleo port.

best regards
Ralf

It looks like the 401 is suffering from the same issue as the 411 on the PYBLITEV10.
