UNIV3 AN0/AN1 analog pins

[kneelo]

Hi,

Are the voltage levels connected to AN0 and AN1 on the UNIV 3 processor used in the firmware? I am designing hardware for an energy monitor so would like to use these analog inputs for extra channels if they are just for information.

I have had a look at the switch module univ_3-1-3-1-rev1 code and these pins seem to be initialised but then I cant see them used anywhere.

Thanks
Neil

Both pins are used.
AN0 is used in the bootloader to measure supply voltage. R4 and R5 resistors are used for that in each module.

AN1 is used in the bootloader to define bootloader working mode.
You can read more about that here:

Thanks for the response... I forgot to look at the boot loader.
