Lightweight USB Device Stack
- Lightweight and fast
- Event-driven process workflow
- Completely separated USB hardware driver and usb core
- Easy to use.
Supported hardware
| HW driver | Written on | Endpoints | Features | MCU series |
|---|---|---|---|---|
| usb_stmv0 | GCC C | 8 | Internal S/N, Doublebuffered | STM32L0x2 STM32L0x3 STM32L4x2 STM32L4x3 STM32F0x2 STM32F0x8 |
| usb_stmv0a | GCC ASM | 8 | Internal S/N, Doublebuffered | STM32L0x2 STM32L0x3 STM32L4x2 STM32L4x3 STM32F0x2 STM32F0x8 |
| usb_stmv1 | GCC C | 8 | Internal S/N, Doublebuffered | STM32L1xx |
| usb_stmv1a | GCC ASM | 8 | Internal S/N, Doublebuffered | STM32L1xx |
Single physical 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.
Tested with STM32L052, STM31L100
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
