Good news everyone! A new free and open source USB stack is now available for PIC microcontrollers. Today we finished testing and prepared a simple echo test that works with PIC 18F and 24F. We hope a demo release will get more developers involved. A release package and overview are in the forum. As always, thanks to Honken and JTR for making this possible.
Microchip has a free-as-in-beer USB firmware for the PIC microcontroller, but it can’t be redistributed. For a project like the USB IR Toy, we can give you our source code but not the USB source. You have to get that on your own from Microchip. It’s not a huge problem, but it is a barrier for people new to PICs. We used the Microchip firmware because it works great and there wasn’t an alternative.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. 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 code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
