tinyusb is an open-source (BSD-licensed) USB Host/Device/OTG stack for embedded micro-controllers, especially ARM MCUs. It is designed to be user-friendly in term of configuration and out-of-the-box running experience.

In addition to running without an RTOS, tinyusb can run across multiple RTOS vendors. More documents and API reference can be found at http://docs.tinyusb.org

Features

Device

• HID Mouse
• HID Keyboard
• HID Generic
• Communication Class (CDC)
• Mass Storage Class (MSC)

Host

** Most active development is on the Device stack. The Host stack is largely untested.**

• HID Mouse
• HID Keyboard
• HID Generic (coming soon)
• Communication Device Class (CDC)
• Mass Storage Class (MSC)
• Hub currently only support 1 level of hub (due to my laziness)

RTOS

Currently the following OS are supported with tinyusb out of the box with a simple change of CFG_TUSB_OS macro.

• None OS
• FreeRTOS
• MyNewt

Toolchains

You can compile with any of following toolchains, however, the stack requires C99 to build with

• GCC
• lpcxpresso
• Keil MDK
• IAR Workbench

Supported MCUs

The stack supports the following MCUs

• LPC11uxx
• LPC13uxx (12 bit ADC)
• LPC175x_6x
• LPC43xx
• MicroChip SAMD21
• MicroChip SAMD51
• Nordic nRF52840

Here is the list of supported Boards in the code base

Getting Started

Here is the details for getting started with the stack.

Uses

TinyUSB is currently used by these other projects:

• nRF52840 UF2 Bootloader
• CircuitPython
