As a another user pointed out there is a onboard chip that you could use aswell. The ATMega32u is integrated in the latte Panda and it has native USB support. There are a lot of keyboard projects that's based on that chip. Have a look at deskthority and geekhack.

[@SzymonJakubiak]

How does it handle fast interrupts for example those coming from a rotary encoder attached to a motor? Arduino has this bad behaviour of skipping/acknowledging interrupts if the interrupt generated is too fast...this was also because Arduino had a clock speed of 16MHz...with 48MHz, does that perform any better? Secondly, I wanted to ask about code latency...what is the latency produced due to the code itself? I'm guessing it is less but that caused problems in my Arduino too. Please reply.And the interrupts I mentioned are pretty fast....assume a 120RPM ...i.e. 2 RPS motor and 60 spokes/revolution.... that's 120Hz: the rate at which the interrupt is being called every second...and this happens to be too fast for the Arduino.

The Teensy's also have very powerful DMA... This allows to control eight Strings of digital or so called adressable (They actually aren't adressable) LEDs at a time, since at above about 1000 LED's the refresh rate gets to low. With the OctoWS2811 library for the Teensy's, you can control huge amounts of LEDs. And the best thing about this is, that sending out the actual data signal does not slow down or affect the CPU, it is managed by them DMA-Controller. The CPU can continue working while the data signal is sent out. Combined with other really neat features like the DSP-instructions (very useful for FFT), this facilitated me to build a 12^3 RGB LED-Cube with a Teensy 3.6.

[@MaltWhiskey]

Did you use TH or SMD for your cube? I’m going to make a 15^3 or 16^3 using HexaWS2811, but am still in the process of designing. How did you build your jig? I have made a 9^3 cube with a teensy 3.5 see my page if you’d like. I sends all data using DMA over SPI, taking no processor power away from calculations. But that one was made using old tech, dumb RGB leds and led drivers. If you have any insight available for me i’d appreciate it ;-)

[@hallolo2]

@@MaltWhiskey I used TH; WS2811-F8 from China. These work fine on 5V and with OctoWS2811. I only built an one-dimensional jig with 3D-printed sockets for the LEDs, fixing them on one line in regular distances (50mm). Then, two 0.6mm copper wires connect the 12 LEDs in a line and supply them with 5V. The data pins are bent sideways, then 12 of these "sticks" get soldered to an array of 12^2 by soldering the sideways bent data pins together... Finally, putting these arrays parallel to each other, make up the whole cube.... I ommitted many many details since a YT comment is not really a good way to explain something like this. I have insight available in form of a dissertation about this project but it is in German and I currently have no English version. You could try to google-translate this dissertation or ask me specific questions about the cube. You can contact me via [CENSORED].

I quite like the STM32F103 as an Arduino alternative and has a USB interface. It is also pretty powerful. It is a little bit more of a pain to flash it with a compatible bootloader, but once you know the process it is a 2-minute thing to do. They are also similarly priced to a nano.

[@rdxdt]

That is the MCU in the Teensy 2.0. USB AVRs have the convenient feature that they have a USB bootloader preloaded, so you pretty much just need a clock source to build your own boards, no programmer required.

STM32 boards require a lot more skill to use to their full potential since the Arduino support for STM32 is less mature then what Teensy offers. The whole point of Teensy is that they give you the complete Arduino experience but with more processing power and more pins, no extra knowledge required, everything is abstracted away for easy usage. STM32 is great but the library and tooling support is just not there yet in the Arduino environment (at least when i checked last time, which is quite some time ago).

Have you looked at V-USB? -- It's a library that lets you bitbang the USB protocol, so you can use it with any AT MEGA chip (including many Arduino ones), even if that chip has NO on board USB support! -- You can even get away without a Crystal OSC (it can measure an offset between it's own internal RC, and the PC's USB signal and use the settings registers to fine tune it's exact running frequency, so that USB continues to work; obviously a 12 MHz OSC is easier to code for, but it's not that bad.)

As far as I can tell an Arduino Micro would have been more than enough for your application, it has about as many pins as the Teensy LC and has native USB support (so it can emulate a keyboard/mouse/controller) but it costs about half as much as the Teensy LC shipped from China.

How does it handle fast interrupts for example those coming from a rotary encoder attached to a motor? Arduino has this bad behaviour of skipping/acknowledging interrupts if the interrupt generated is too fast...this was also because Arduino had a clock speed of 16MHz...with 48MHz, does that perform any better? Secondly, I wanted to ask about code latency...what is the latency produced due to the code itself? I'm guessing it is less but that caused problems in my Arduino too. Please reply.And the interrupts I mentioned are pretty fast....assume a 120RPM ...i.e. 2 RPS motor and 60 spokes/revolution.... that's 120Hz: the rate at which the interrupt is being called every second...and this happens to be too fast for the Arduino. I want to know if this can handle it to a better extent?

Will there be a german version of this video too?

No

how does the "Teensy" compare to the "Bela" board?

Creating a voltage divider with your potentiometer probably wasn't the best idea. I thought the pins do not tolerate 5 volts, how did this not fry the board?

I used 3.3V
