0.7.0

November 7, 2020

Device Controller Driver

• Added new support for Espressif ESP32-S2
• Added new support for Dialog DA1469x
• Enhance STM32 Synopsys
• Support bus events disconnection/suspend/resume/wakeup
• Improve transfer performance with optimizing xfer and fifo size
• Support Highspeed port (OTG_HS) with both internal and external PHY
• Support multiple usb ports with rhport=1 is highspeed on selected MCUs e.g H743, F23. It is possible to have OTG_HS to run on Fullspeed PHY (e.g lacking external PHY)
• Add ISO transfer, fix odd/even frame
• Fix FIFO flush during stall
• Implement dcd_edpt_close() API
• Support F105, F107

Enhance STM32 fsdev

• Improve dcd fifo allocation
• Fix ISTR race condition
• Support remap USB IRQ on supported MCUs
• Implement dcd_edpt_close() API

Enhance NUC 505

• enhance set configure behavior

Enhance SAMD

• Fix race condition with setup packet
• Add SAMD11 option OPT_MCU_SAMD11
• Add SAME5x option OPT_MCU_SAME5X

SAMG

• Fix SAMG control data toggle and stall race condition

Enhance nRF

• Fix hanged when tud_task() is called within critical section (disabled interrupt)
• Fix disconnect bus event not submitted
• Implement ISO transfer and dcd_edpt_close()

USB Device

USBD

• Add new class driver for Bluetooth HCI class driver with example can be found in mynewt-tinyusb-example since it needs mynewt OS to run with.
• Fix USBD endpoint usage racing condition with usbd_edpt_claim()/usbd_edpt_release()
• Added tud_task_event_ready() and osal_queue_empty(). This API is needed to check before enter low power mode with WFI/WFE
• Rename USB IRQ Handler to dcd_int_handler(). Application must define IRQ handler in which it calls this API.
• Add dcd_connect() and dcd_disconnect() to enable/disable internal pullup on D+/D- on supported MCUs.
• Add usbd_edpt_open()
• Remove dcd_set_config()
• Add OPT_OS_CUMSTOM as hook for application to overwrite and/or add their own OS implementation
• Support SET_INTERFACE, GET_INTERFACE request
• Add Logging for debug with optional uart/rtt/swo printf retarget or CFG_TUSB_DEBUG_PRINTF hook
• Add IAR compiler support
• Support multiple configuration descriptors. TUD_CONFIG_DESCRIPTOR() template has extra config_num as 1st argument
• Improve USB Highspeed support with actual link speed detection with dcd_event_bus_reset()
• Enhance class driver management
  • usbd_driver_open() add max length argument, and return length of interface (0 for not supported). Return value is used for finding appropriate driver
  • Add application implemented class driver via usbd_app_driver_get_cb()
  • IAD is handled to assign driver id
• Added tud_descriptor_device_qualifier_cb() callback
• Optimize tu_fifo bulk write/read transfer
• Forward non-std control request to class driver
• Let application handle Microsoft OS 1.0 Descriptors (the 0xEE index string)
• Fix OSAL FreeRTOS yield from ISR
• Rename some configure macro to make it clear that those are used directly for endpoint transfer
  • CFG_TUD_HID_BUFSIZE to CFG_TUD_HID_EP_BUFSIZE
  • CFG_TUD_CDC_EPSIZE to CFG_TUD_CDC_EP_BUFSIZE
  • CFG_TUD_MSC_BUFSIZE to CFG_TUD_MSC_EP_BUFSIZE
  • CFG_TUD_MIDI_EPSIZE to CFG_TUD_MIDI_EP_BUFSIZE

USBNET

• Remove ACM-EEM due to lack of support from host

USBTMC

• Fix descriptors when INT EP is disabled

CDC

• Send zero length packet for end of data when needed
• Add tud_cdc_tx_complete_cb() callback
• Change tud_cdc_n_write_flush() return number of bytes forced to transfer, and flush when writing enough data to fifo

MIDI

• Add packet interface
• Add multiple jack descriptors
• Fix MIDI driver for sysex

DFU Runtime

• fix response to SET_INTERFACE and DFU_GETSTATUS request

HID

• Fix gamepad template descriptor
• Add multiple HID interface API
• Add extra comma to HID_REPORT_ID

USB Host

• Rework USB host stack (still work in progress)

  • Fix compile error with pipehandle
  • Rework usbh control and enumeration as non-blocking

• Improve Hub, MSC, HID host driver

Examples

• Add new hid_composite_freertos
• Add new dynamic_configuration to demonstrate how to switch configuration descriptors
• Add new hid_multiple_interface
• Enhance net_lwip_webserver example
  • Add multiple configuration: RNDIS for Windows, CDC-ECM for macOS (Linux will work with both)
  • Update lwip to STABLE-2_1_2_RELEASE for net_lwip_webserver
• Added new Audio example: audio_test uac2_headsest

New Boards

• Espressif ESP32-S2: saola_1, kaluga_1
• STM32: F746 Nucleo, H743 Eval, H743 Nucleo, F723 discovery, stlink v3 mini, STM32L4r5 Nucleo
• Dialog DA1469x dk pro and dk usb
• Microchip: Great Scoot Gadgets' LUNA, samd11_xplained, D5035-01, atsamd21 xplained pro
• nRF: ItsyBitsy nRF52840
