PCF8575

Ludo Gys asked 3 years 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!

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.
