Re: [avr-gcc-list] TWI pullup resisor values

[Douglas Dotson]

I would think that I should be able to get a simple
device operating at 100K over a 2" distance working
without resorting to this kind of thing. I'm beginning
to think that the slave device is actually bad. I'm
going to try another one and if acts the same way then
I'll have to start getting creative.
