Topics

Here is a list of all topics with brief descriptions:

phyduino.py	The Phyduino Pico library: import phyduino as mcu, with MicroPython-style names
Pins	Pin names, the pin map, digital pins and PWM
On-board LED	The green built-in LED on GPIO5
Analog inputs	Reading A0-A5, the same functions on every pin
Power and temperature	The USB-C supply (VBUS), USB Power Delivery and the RP2040's temperature
Header buses	I2C, SPI and UART set up on the header pins
External ADC	The MAX11635 chip behind A3-A5, by channel
arduino.py	Optional Arduino-style functions: from arduino import *, with Arduino's names and ranges
Digital I/O	Pins as inputs and outputs: pinMode(), digitalWrite(), digitalRead() and the pin constants
Analog I/O	Reading A0-A5 with analogRead() (0-1023) and PWM with analogWrite() (0-255), with their settings
Tones	Notes on a piezo buzzer: tone() and noTone()
Time	Waiting and timing: delay(), delayMicroseconds(), millis() and micros()
Math	Rescaling and limiting numbers: map() and constrain()
