Hi Danilo,
Try searching for Getadc.
The search without the "C" doesn't find anything.
Regards

you might want to check the bascom help for : GETAD2051 and getad as mentioned.
you can also use an a/d converter with i2c or SPI control.

when your micro has the comparator, you could use the getad2051 but otherwise you need an external a/d converter.

this processor has NO comparator. It also has no A/D converter so you need a different processor or an external A/D

i could not find a datasheet of your chip but i looked at the AT89S52 which did not had this comparator.
when it has one : just look in the help for the circuit. getad2051
