Measure the supply voltage of an AVR

Hi, There. I need to measure the voltage that supplies the AVR 8bit ATtiny series using this very same MCU. Maybe I can use the Vgap reference 1.1V But I would like to ask if this can be done directly in Flowcode 11?

It should be easy to measure the Vcc within Flowcode using an analogue input and the voltage reference. A web search brought up
this article and
this article which might be of help.

Hi
Following on from above, I think Steve001 posted a solution in the old forum. A search there would probably be worth trying.
