TinyUSB Changelog

Master branch (WIP)

Breaking

  • TinyUSB does not directly implement USB IRQ Handler function anymore. Application must implement IRQ Handler and invoke tud_int_handler(rhport). This is due to:
    • IRQ Handler name can be different across system depending on the startup
    • Some OS need to execute enterISR()/exitISR() to work properly, also tracing tool may need to insert trace ISR enter/exit to record usb event
    • Give application full control of IRQ handler, can be useful e.g signaling there is new usb event without constant polling

MCU

  • Added support for Espressif ESP32-S2 and saola-1 board
  • All default IRQ Handler is renamed to dcd_int_handler()
  • STM32 Synopsys
    • Bus events disconnection/suspend/resume are supported
  • Added dcd_connect() and dcd_disconnect() to enable/disable internal pullup on D+/D- on supported MCUs.
  • Added dcd_edpt_close() for STM32 FSDev

Device Stack

  • tud_cdc_n_write_flush() return number of bytes forced to transfer instead of bool
  • Support multiple configuration descriptors. TUD_CONFIG_DESCRIPTOR() template has extra config_num as 1st argument
  • Improve class driver management
    • Driver detection is done by open() API
    • IAD is handled to assign driver id
  • Improve Alternate Interface request with SET_INTERFACE() (not fully supported yet).
  • Fixed CDC ZLP response #260
  • Remove ACM-EEM due to lack of support from host

Others

  • Added OPT_OS_CUMSTOM as hook for application to overwrite and/or add their own OS implementation
  • Enhanced net_lwip_webserver example with multiple configuration: RNDIS for Windows, CDC-ECM for macOS (Linux will work with both)

0.6.0 - 2019.03.30

Added CONTRIBUTORS.md to give proper credit for contributors to the stack. Special thanks to Nathan Conrad, Peter Lawrence and William D. Jones and others for spending their precious time to add lots of features and ports for this release.

0.5.0 (Initial Release) - 2019.07.10

First release, device stack works great, host stack works but still need improvement.

  • Special thanks to @adafruit team, especially @tannewt to help out immensely to rework device stack: simplify osal & control transfer, adding SAMD21/SAMD51 ports, writing porting docs, adding MIDI class support etc...
  • Thanks to @cr1901 for adding STM32F4 port.
  • Thanks to @PTS93 and @todbot for HID raw API
