Arduino vs teensy for keyboard emulation

[simondid]

hey

so i'm about to start my Gameboy zero w build and i'm in the process off deciding how i wanna handle input to the pi which goth me thinking
is it really necessary to use the 3 times as fast teensy over the arduino nano ore pro mini?

my project is not gonna be a normal retro pi build as it's gonna be a controller for my Sonos based sound system which means that the ability to put my system in some kind of low power mode is gonna be important i know that the Arduino can do this with a sleep mode of less than 1 MA i'm unsure on how low you can get the teensy in sleep mode?

so how i see it

teensy 3.2
- price 15 + times the price off an Arduino nano
+ 2-3 times fast processing then the arduino nano
- unknown sleep mode power usage

Arduino
+ low price
- slow processing


has anyone tried using an arduino instead of the teensy and is there any noticeable difference between the input speeds?

Check the Wiki for the Leonardo Pro micro. It is based on arduino, so it should bei a good reference to what you are able to Do with an arduino nano.

Seconded on the Pro Micro. I got mine for <$5 and has the exact same layout as the Teensy.

are you experiencing any lags / processing speed related issues? with the pro micro arduino

I've just finished a build with a Leonardo Pro Micro. No issues whatsoever.

okay great thanks is the the 8 mhz ore 16 mhz version youre using?

16mhz

I hate to revive an old thread, but I use a Leonardo in my build. I have experienced quite a bit of input lag vs a wired USB SNES controller (Buffalo). The Buffalo controller responds noticeably quicker. Does anyone know if this could be improved with a Teensy or is it just the nature of the build?

What software are you running on your Leonardo fox? I found a script for buttons only worked fine with my pro micro, but a script that included joysticks I was using previously was problematic when it came to response time. Perhaps another script might give better results, or debounce is set way too high?
