0.14.0

August 23, 2022

• Improve compiler support for CCRX and IAR
• Add timeout to osal_queue_receive()
• Add tud_task_ext(timeout, in_isr) as generic version of tud_task(). Same as tuh_task_ext(), tuh_task()
• Enable more warnings -Wnull-dereference -Wuninitialized -Wunused -Wredundant-decls -Wconversion

Add new examples

• host/bare_api to demonstrate generic (app-level) enumeration and endpoint transfer
• dual/host_hid_to_device_cdc to run both device and host stack concurrently, get HID report from host and print out to device CDC. This example only work with multiple-controller MCUs and rp2040 with the help of pio-usb as added controller.

Controller Driver (DCD & HCD)

• Enhance rhports management to better support dual roles

  • CFG_TUD_ENABLED/CFG_TUH_ENABLED, CFG_TUD_MAX_SPEED/CFG_TUH_MAX_SPEED can be used to replace CFG_TUSB_RHPORT0_MODE/CFG_TUSB_RHPORT1_MODE
  • tud_init(rhport), tuh_init(rhport) can be used to init stack on specified roothub port (controller) instead of tusb_init(void)

• Add dcd/hcd port specific defines TUP_ (stand for tinyusb port-specific)

dwc2

• Update to support stm32 h72x, h73x with only 1 otg controller
• Fix overwrite with grstctl when disable endpoint

EHCI

• Fix an issue with EHCI driver

msp430

• Fix for possible bug in msp430-elf-gcc 9.3.0

nrf5x

• Fix DMA access race condition using atomic function

pic32

• Fix PIC32 sanity

rp2040

• Add PICO-PIO-USB as controller (device/host) support for rp2040
• Use shared IRQ handlers, so user can also hook the USB IRQ
• Fix resumed signal not reported to device stack

stm32fsdev

• Add support for stm32wb55

Device Stack

• [Audio] Add support for feedback endpoint computation

  • New API tud_audio_feedback_params_cb(), tud_audio_feedback_interval_isr().
  • Supported computation method are: frequency with fixed/float or power of 2. Feedback with fifo count is not yet supported.
  • Fix nitfs (should be 3) in TUD_AUDIO_HEADSET_STEREO_DESCRIPTOR
  • Fix typo in audiod_rx_done_cb()

• [DFU] Fix coexistence with other interfaces BTH, RNDIS

• [MSC] Fix inquiry response additional length field

• [Vendor] Improve write performance

Host Stack

• Add new API tuh_configure(rhport, cfg_id, cfg_param) for dynamic port specific behavior configuration
• [HID] Open OUT endpoint if available
• [Hub] hub clear port and device interrupts

[USBH] Major improvement

• Rework usbh control transfer with complete callback. New API tuh_control_xfer() though still only carry 1 usbh (no queueing) at a time.

• Add generic endpoint transfer with tuh_edpt_open(), tuh_edpt_xfer(). Require CFG_TUH_API_EDPT_XFER=1

• Support app-level enumeration with new APIs

  • tuh_descriptor_get(), tuh_descriptor_get_device(), tuh_descriptor_get_configuration(), tuh_descriptor_get_hid_report()
  • tuh_descriptor_get_string(), tuh_descriptor_get_manufacturer_string(), tuh_descriptor_get_product_string(), tuh_descriptor_get_serial_string()
  • Also add _sync() as sync/blocking version for above APIs
