Ordered an AD2 today, should be delivered tomorrow and the moment i completed the transaction i realized ... i need a Logic-Level-Converter ... Arduino 5V ... AD2 3.3V ... that's the kind of "i am afraid of missing something" i was talking about.
A TXS0108E based logic-level-converter should do the trick?
To set the record straight, i consider myself a newbie compared to the average scope-using eevblog user, i have been soldering the past ~10 years and repaired simple electronics for family and friends but i am not the "bins of ic's / gates etc in the cupboard" type, rather the "if a resistor or a big cap doesn't help let's put in an even bigger cap ... or plop in an arduino (even for the most basic logic things)"... i was always limited to the "multimeter-world". Only 1 short in 10 years
.
Being able to solve differential equations in advanced physics in highschool and scoring 100% on every test didn't help me a bit, when circuits do not behave as ideal as "school theory", when every component starts to be a bit of everyting (L-C-R) and even changes behaviour with frequency ... i never had enough of a reason to get a scope but finally decided i don't need a reason to get one.
