You're Writing Development on a Micro Controller?

So you're writing seplus plus code to work on a micro controller. I'd always ot that my mental model, i guess, of doing development on a micre controller is that performance is just absolutely essential. And like, if you want to get anything to work rite and feel real time, like, especially if you're trying to get it to mimic what you're drawing with your hand, you got to have every last little ounce of performance h you can get. It sounds like there would be so many, i would have guessed that there'd be so many steps in there, thatt, therewould be a lot of latency. But it sounds like, i guess it's reasonable
