What Is tinyusb
tinyusb is an open-source (BSD-licensed) USB Host/Device/OTG stack for embedded micro-controller. It is developed using Test-Driven Development (TDD) approach to eliminate bugs as soon as possible.
Features
designed to be simple and run out-of-the-box provided the configuration is correct.
Host
- HID Mouse
- HID Keyboard
- HID Generic (comming soon)
- Communication Device Class (CDC)
- Mass Storage Class (MSC)
- Hub
- Only support 1 level of hub (due to my laziness)
Device
- HID Mouse
- HID Keyboard
- HID Generic (comming soon)
- Communication Class (CDC)
- Mass Storage Class (MSC)
RTOS
tinyusb is designed to be OS-ware and run across RTOS vendors, thanks to its OS Abstraction Layer (OSAL). However, it can also run without an RTOS (OSAL will be expanded to be a state machine in this case). Currently the following OS can be run with tinyusb (out of the box).
- None OS
- FreeRTOS
- CMSIS RTX
Getting Started
coming soon ...
Supported MCUs
- NXP
- LPC11uxx
- LPC13uxx (12 bit ADC)
- LPC175x_6x
- LPC43xx
Supported Toolchains
The following toolchains are supported
- lpcxpresso/redsuite
- Keil MDK
- IAR Workbench
Known Issues
- LPC11uxx & LPC13uxx cannot able to STALL Control OUT endpoint !!! --> unsupported with data out request may cause host stuck with control transfer forever. (reproduce: enable keyboard + mouse, return error in set report of hid_device)
How Can I Help
If you find my little USB stack is useful, please take some time to file any issues that you encountered. It is not necessary to be a software bug, it can be a question, request, suggestion etc. We can consider each github's issue as a forum's topic. Alternatively, you can buy me a cup of coffee if you happen to be in Hochiminh city.
