Lightweight USB Device Stack
- Lightweight and fast
- Event-driven process workflow
- Completely separated USB hardware driver and middleware
- Easy to use.
Supported hardware
| MCU series | Driver Name | Written on | Endpoints (1) | Internal S/N | Doublebuffered transfer |
|---|---|---|---|---|---|
| STM32L0/F0 | usb_stml0a | GCC ASM | 8 | FNV1A 32bit | ISO, BULK OUT, BULK IN (2) |
| STM32L0/F0 | usb_stmv0 | C | 8 | FNV1A 32bit | ISO, BULK OUT, BULK IN (2) |
Single physicsl endpoint can be used to implement
- one bi-directional/single-buffer logical endpoint (CONTROL)
- one mono-directional/double-buffer logical endpoint (BULK OR ISOCHRONOUS)
- two mono-directional/single-buffer logical endpoints (BULK OR INTERRUPT)
At this moment BULK IN endpoint can use both buffers, but it is not real doublebuffered.
Implemented definitions for classes
- USB HID based on Device Class Definition for Human Interface Devices (HID) Version 1.11
- USB DFU based on USB Device Firmware Upgrade Specification, Revision 1.1
- USB CDC based on Class definitions for Communication Devices 1.2
