Hello,

I get following compiler error on FC7 after trying DS3231 RTC module (Otherwise system works OK with i2c OLED display)

FC7 version: 7.2.1.4

Could you try the updates from here....

If that does not fix the issue, please post your project file (*.fcfx)

Hello

After updates RTC is working ok, thanks.

I also noticed that DS3231 component from FC6 is working ok in FC7. (at least on arduino?)

How usually FC6 components are compatible with FC7? Does it depend on compiler?

Yes, it would depend mainly on if there is any embedded C in the component
