How to have CubeMX configure a peripheral but NOT enable it?

[Andrew Neil]

I think it's a common scenario to have (at least some) peripherals which are not enabled until needed?

Or, perhaps, just configured at start-up, but not enabled until actually needed.

eg, an RTC alarm.

But CubeMX doesn't seem to support this:

• If you don't enable the peripheral/feature, it won't let you configure it;
• If you do enable it, it will be enabled at startup - no option to leave it til "later"

Or have I missed something/?

Hello @Andrew Neil ,

Thank you for rising this up.

I escalated your request internally to take a closer look at the problem (via Internal ticket number: 200359).

STM2CubeMX Project Manager Advanced Settings has "Do not generate function call" options for the various _Init functions.

Ah yes - that's it!

Although, in the specific case of the RTC alarm, it still just creates one MX_RTC_Init function - whereas I'd have thought it more likely that you'd want to configure and start the RTC itself separately from setting an alarm?

But that's a different question ...
