The TinyUSB open source cross-platform USB stack, designed specifically for embedded devices, is set to gain a new feature in a future release: support for the eptri tri-FIFO USB device, offering 16 IN and 16 OUT endpoints without consuming excessive resources.
Supported on a range of microcontrollers, the TinyUSB stack aims to offer memory- and thread-safe USB control on resource-constrained devices without using dynamic allocation. The stack is set to get a shiny new function in its next release, courtesy of a pull request from Sean Cross to add support for a tri-FIFO device mode: eptri.

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.
