Library for the U of T Physics Analog Shield (Introduction to Electronics). More...

#include <Arduino.h>

Classes
class	AnalogShield
	Encoder, switch, temperature signals, potentiometer and LEDs on the Analog Shield. More...

Namespaces
namespace	AnalogShieldPins
	Shield signals by Arduino pin, from the Rev-C schematic.

Macros
Library version
Keep equal to version= in library.properties; CI checks that they match.
#define	ANALOG_SHIELD_VERSION "0.1.2"
	Full version, as in library.properties (may carry a suffix such as "-rc.1").
#define	ANALOG_SHIELD_VERSION_MAJOR 0
	Major version: incompatible API changes.
#define	ANALOG_SHIELD_VERSION_MINOR 1
	Minor version: new features, compatible.
#define	ANALOG_SHIELD_VERSION_PATCH 2
	Patch version: fixes only.

Enumerations
enum class	TempSource : uint8_t { SENSOR , MCU , EXT }
	Temperature signal to read with AnalogShield::TempRaw() or AnalogShield::TempMillivolts(). More...

Variables
Analog header (J4)
A2 is not connected.
constexpr uint8_t	AnalogShieldPins::TEMP_SIG_MCU = A0
	Conditioned temperature signal, JP2 at Internal (RP2040 ADC).

	Rotary encoder push switch, active low (pulled up to VDD).
constexpr uint8_t	AnalogShieldPins::ENC_A = 3
	Rotary encoder channel A, active low (pulled up to VDD).
constexpr uint8_t	AnalogShieldPins::ENC_B = 4
	Rotary encoder channel B, active low (pulled up to VDD).

constexpr uint8_t	AnalogShieldPins::LED1 = 6
	D1 green LED, active low (anode to VDD).

Detailed Description

Library for the U of T Physics Analog Shield (Introduction to Electronics).

Pins use Arduino names (A0, 2, ...), never MCU GPIO numbers, so the library works on any Uno-style board (Phyduino Pico, Uno R3/R4).
