Device Stack
- Human Interface Device (HID): Keyboard, Mouse, Generic
- Communication Class (CDC)
- Mass Storage Class (MSC)
- Musical Instrument Digital Interface (MIDI)
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
- Nordic: nRF52840
- NXP: LPC11Uxx, LPC13xx, LPC175x_6x, LPC177x_8x, LPC18xx, LPC40xx, LPC43xx
- MicroChip: SAMD21, SAMD51
- ST: STM32F4
Here is the list of supported Boards
Compiler & IDE
The stack is developed with GCC compiler, and should be compilable with others. Folder examples provide Makefile and Segger Embedded Studio build support.
Getting Started
Here is the details for getting started with the stack.
