lib_xud merges the existing sc_xud and lib_usb (a fork of sc_xud) and replaces them both. It includes an API that supports both previous libraries providing a unified and maintained library going forward.
The XMOS USB Device (XUD) library provides a low-level interface to USB. lib_xud is a software defined, industry-standard, USB library that allows you to control an USB bus via xCORE ports.
The library provides functionality to act as a USB device only.
This library is for use with xCORE-200 Series or xCORE-AI series devices only, previous generations of xCORE devices are no longer supported.
Note, at points lib_xud will run in "fast mode" this is a requirement to meet timing.
- USB 2.0 Full-speed (12Mbps) and High-speed (480Mbps)
- Device mode
- Bulk, control, interrupt and isochronous endpoint types supported
- SOF tokens are not CRC checked on XS3 based devices (see tests/test_sof_badcrc)
- Documentation not updated for removal of XS1 and addition of XS3 based devices
The CHANGELOG contains information about the current and previous versions. For a list of direct dependencies, look for DEPENDENT_MODULES in lib_xud/module_build_info.
