0.15.0

February 10, 2023

• Add codespell to detect typo
• Add support for fuzzing and badge for oss-fuzz
• [osal]
  • Allow the use of non-static allocation for FreeRTOS
  • Fix FreeRTOS wrong task switch in some cases
• Fix tu_fifo memory overflown when repeatedly write to overwritable fifo (accumulated more than 2 depths)
• Better support for IAR (ARM) with ci build check for stm32 mcus.
• Fix Windows build for some mingw gnu make situations

Controller Driver (DCD & HCD)

• Add new port support (WIP) for WCH CH32V307 USB Highspeed
• Add new port support (WIP) for PIC32MM/MX & PIC24

nRF

• Fix endpoint internal state when closed
• Fix reception of large ISO packets

rp2040

• [dcd] Implement workaround for Errata 15. This enable SOF when bulk-in endpoint is in use and reduce its bandwidth to only 80%
• [hcd] Fix shared irq slots filling up when hcd_init() is called multiple times
• [hcd] Support host bulk endpoint using hw "interrupt" endpoint. Note speed limit is 64KB/s

samd

• [dcd] Add support for ISO endpoint

dwc2

• [dcd] Add support for stm32u5xx

esp32sx

• Fix Isochronous transfers only transmitted on even frame

lpc_ip3511

• [dcd] Add isochronous support and fix endpoint accidental write

ft90x

• Improve and enhance support for FT9xx MCU, tested with more examples

Device Stack

Video

• Add support for MJPEG
• Fix probe on macOS

MIDI

• Support port name strings
• fix MS Header wTotalLength computation

HID

• Add FIDO descriptor template
• change length in tud_hid_report_complete_cb() from uint8_t to uint16_t

CDC

• Fix autoflush for FIFO < MPS
• Fix tx fifo memory overflown when DTR is not set and tud_cdc_write() is called repeatedly with large enough data

USBTMC

• Fix packet size with highspeed

Host Stack

• Retry a few times with transfers in enumeration since device can be unstable when starting up
• [MSC] Rework host mass storage API. Add new host/msc_file_explorer example

CDC

• Add support for host cdc
• Fix host cdc with device without IAD e.g Arduino Due
