PCF8575

Ludo Gys asked 7 months ago

Sorry, the first submission went wrong. The question is if anyone has a recommendation for a good Arduino library to work with multiple PCF 8575 modules. Any suggestion is more than welcome. Thanks!

Thank you Sara, I think it is going to be straithforward with the addressing via I2C. In any case if I find a problem I will post on it.

My experience is doing it straightforward using the wire library works great. They will work on 3V3 just keep the pull ups 1.5 to 3K range.
