TinyUSB

TinyUSB is an open-source cross-platform USB Host/Device stack for embedded system.

hw/mcu Low level mcu core & peripheral drivers
lib Source files from 3rd party such as freeRTOS, fatfs etc ...
src All sources files for TinyUSB stack itself.
tests Unit tests for the stack
tools Files used internally

Device Stack

  • Human Interface Device (HID): Keyboard, Mouse, Generic
  • Communication Class (CDC)
  • Mass Storage Class (MSC)

Host Stack

Most active development is on the Device stack. The Host stack is under rework and largely untested.

  • Human Interface Device (HID): Keyboard, Mouse, Generic
  • Mass Storage Class (MSC)
  • Hub currently only support 1 level of hub (due to my laziness)

OS Abtraction layer

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

  • No OS
  • FreeRTOS
  • MyNewt (work in progress)

Supported MCUs

The stack supports the following MCUs

  • NXP: LPC11Uxx, LPC13xx, LPC175x_6x, LPC177x_8x, LPC40xx, LPC43xx
  • MicroChip: SAMD21, SAMD51 (device only)
  • Nordic: nRF52840

Here is the list of supported Boards

Compiler & IDE

The stack is developed with GCC compiler, and should be compilable with others. However, it requires C99 to build with. Folder examples provide Makefile and Segger Embedded Studio build support.

Getting Started

Here is the details for getting started with the stack.

Uses

TinyUSB is currently used by these other projects:
