int	ADC_FULL_SCALE_MILLIVOLTS = 3300
	Maximum input voltage of A0-A2 (RP2040 ADC) in millivolts.
int	EXT_ADC_FULL_SCALE_MILLIVOLTS = 2048
	Maximum input voltage A3-A5 (MAX11635, LM4040 reference on AREF) in millivolts.
	led = Led()
	The on-board LED: a Led object.

Detailed Description

Phyduino Pico board library for MicroPython.

Built into the Phyduino Pico MicroPython firmware, so your own main.py can use it:

import phyduino as mcu
 
mcu.led.on()
print(mcu.analog_volts("A3"))
button = mcu.pin("D2", "in", pull="up")

Pins use the names printed on the board: "D0"-"D13", "D18", "D19", "A0"-"A5", plus "SDA", "SCL" and "LED". Names are not case-sensitive.

A0-A2 are read by the RP2040 (0-3.3 V). A3-A5 are read by the on-board MAX11635 ADC (0-2.048 V) and are analog only. The same functions work on all six analog inputs.
