History
Angus Gratton 22f1d76633 shared/tinyusb: Use device event hook to schedule USB task. 
Previously MicroPython ports would linker-wrap dcd_event_handler
in order to schedule the USB task callback to run when needed.

TinyUSB 0.16 added proper support for an event hook to do the
same thing without the hacky linker wrapping.

This work was funded through GitHub Sponsors.

MicroPython port to Alif Ensemble MCUs

This is a port of MicroPython to the Alif Ensemble series of microcontrollers.

Initial development of this Alif port was sponsored by OpenMV LLC.

Features currently supported:

  • UART REPL.
  • TinyUSB with CDC and MSC device support.
  • Octal SPI flash with XIP mode.
  • machine.Pin support with named pins.
  • machine.UART, machine.SPI, machine.I2C, machine.RTC peripherals.
  • WiFi and Bluetooth using cyw43.
  • Dual core support of the HE and HP cores using Open-AMP.
  • Low power modes.

The following more advanced features will follow later:

  • Ethernet support.
  • SDRAM support.
  • Other machine modules.
