I2C pullups needed
Are pullups needed on pins 28 and 29 for the SDA and SCL lines?
It looks like they aren't there in various example circuits, but
there is a 10k resistor between SDA and RESn.· What's that for?
Once the pins turn into GPIO after bootup, will I need to have
pullups to bit-bang the i2c from spin?
Thanks,
MX

direction when bit-banging the I2C, correct?

1+1=10
