#ADAFRUIT TRINKET MULTITHREAD PRO#

Above this code are the contents of TrinketKeyboardC. Implemented and analyzed dynamic control to optimize string stability of a connected system of 6 trains designed using Adafruit Pro Trinket microcontrollers. If needed, it would be easy to bring over more utility functions from Adafruit’s library, but this will do for now: My minimal example does not toggle any LEDs and only has one button wired between pin #0 (PB0) and ground, which sends a string of capital A’s when pressed. The sensor circuit board is connected to the Adafruit Trinket M0 (see. That was basically it! I did a few small tweaks, including a few pointer casts so the compiler would not complain, and remove some needless #includes. upgrade, and is now configured as a multithreading system, meaning that several.

Remove everything else except the above file, usbconfig.h and usbdrv directory.

Add 30 lines of code in the end - pressKey from the C++ part of the library and a simple main() method.

Rename TrinketKeyboardC.c to main.c (we’ll only have one.

I decided to adapt the excellent base code in Adafruit Trinket USB GitHub repository, but trim the keyboard example to bare essentials (my next step will be to transform it into a USB MIDI device, so the less code I have to adapt, the better). Time to do some chopping! Slimming Down the TrinketKeyboard Example Also, all USB MIDI examples are on “bare metal”, so the Adafruit example Arduino code would require deeper knowledge of Arduino inner workings than I have.

I somewhat dislike the high-level Arduino environment in cases where low-level performance is needed (and the V-USB implementation is one of those places), and for my later MIDI part, I will need fine-grained control to juggle serial communication and USB.

Adafruit examples for USB come in Arduino form.

Now I am planning a project which involves transforming the very compact, but already USB-enabled Trinket into a USB MIDI device. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together.

Among them was the lovely Adafruit Trinket (which actually came as a free bonus because I spent way too much on black friday :). Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. I ordered a big chunk of things recently from Adafruit shop and Sparkfun. I have a bigger (USB MIDI related) project posting coming up, but just wanted share a small nugget already. Use the 3V one to interface with sensors and devices that need 3V logic, or when you want to power it off of a LiPo battery.

Both work the same, but have different operating logic voltages.

Happy New Year 2016! After a long hiatus in electronics, I have been quite busy in the last month or so. Simply use a USB v2 port or a USB hub in between There are two versions of the Trinket.
