What's in it

The release notes are the 0.1.0-rc.1 section of CHANGELOG.md. This is the first version.

• phyduino.py, built into the firmware:
  • Pins by board name (PINS, pin(), gpio()), with pwm() and led.
  • Analog reads on A0–A5. A3–A5 use the on-board MAX11635, also available directly through external_adc().
  • vbus_volts(), cpu_temperature(), and usb_pd() for STUSB4500 USB-PD profiles (10 W limit).
  • i2c(), spi() and uart() on the header pins, and version().
• arduino.py, also built in: Arduino-style functions ande(), digitalWrite(), analogRead() (10-bit),analogWrite()(8-bit),tone(), delay(), millis(), map(), constrain(), and HIGH, LOWandA0–A5`.
• Board definition in boards/PHYDUINO_PICO/ and `tools/be firmware.
• 50 examples: 25 in each of two sets, examples/arduino/ (with setup() and loop()) and examples/phyduino/ (plain MicroPython).
• Host tests: 166, run with pytest against a fake `machine
• Documentation site with the Doxygen API reference, on GitHub Pages.

Known issue: after pwm("LED"), led no longer changes the LED. Run pin("LED", "out") to free the pin.
