Wire library doesn't support clock skew. #334

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago

What change would like to see?
I wanted to see clock_skew support.
Why?
Because slaves might needed to make some job that takes long time. So If we 
drive SCL low, than master knows that slave is busy.

Would this cause any incompatibilities with previous versions?  If so, how
can these be mitigated?
No, it doesn't cause any incompatibility.

When I think this, it's needed to be "defect" instead of enhancement, since 
current slave code "drops" packages, which is defect. Proper approach is using 
clock stretching/skewing. So please convert this request to defect.

I found that code supports clock stretching actually. but package dropping. So 
please close this. Will open as defect for dropping packets.
Regards.
