Defines all available digital input/output pins of ATtinyX5, with additional pin imaginary numbering (as for an Arduino board).

Each symbol is in the form Dxx_Pyz, where xx is the imaginary pin number, y is the port letter (B, C or D) and z is the bit number for that pin within its port.

Enumerator
D0_PB0	Pin PB0 (D0)
D1_PB1	Pin PB1 (D1)
D2_PB2	Pin PB2 (D2)
D3_PB3	Pin PB3 (D3)
D4_PB4	Pin PB4 (D4)
LED	Shortcut for LED pin, arbitrarily chosen to be D0.

◆ AnalogReference

enum class board::AnalogReference : uint8_t

strong

Defines available voltage references of ATtinyX5, used for analog input.

Enumerator
AREF	Voltage reference is given by the `AREF` (PB0) pin.
AVCC	Voltage reference is given by the `Vcc` pin.
INTERNAL_1_1V	Voltage reference is internal 1.1V reference, generated from the internal bandgap reference.

◆ AnalogPin

enum class board::AnalogPin : uint8_t

strong

Defines all available analog input pins of ATtinyX5, with reference to ATtinyX5 pins.

A2	Pin ADC2 (PB4)
A3	Pin ADC3 (PB3)
BANDGAP	Bandgap reference.

Each symbol is in the form Dxx_Pyz_OCuv, where xx is the imaginary pin number , y is the port letter (B, C or D), z is the bit number for that pin within its port, u is the number of the timer used by this PWM pin and v the letter indicating which compare register of the timer this PWM pin is mapped to.

Definition at line 157 of file attiny_x5.h.

◆ ExternalInterruptPin

enum class board::ExternalInterruptPin : uint8_t

strong

Defines all digital output pins of ATtinyX5, usable as direct external interrupt pins.

Definition at line 176 of file attiny_x5.h.

◆ InterruptPin

enum class board::InterruptPin : uint8_t

strong

Defines all digital output pins of ATtinyX5, usable as pin change interrupt (PCI) pins.

Each symbol is in the form Dxx_Pyz_PCIu, where xx is the imaginary pin number, y is the port letter (B, C or D), z is the bit number for that pin within its port and u is the number of the PCI vector for that pin.

◆ USART

enum class board::USART : uint8_t

strong

Defines all USART modules of ATtinyX5, actually none at all.

enum class board::Timer : uint8_t

strong

Defines all timers available for ATtinyX5.

Enumerator
TIMER0	Timer0 (8 bits)
TIMER1	Timer1 (8 bits)

Definition at line 208 of file attiny_x5.h.

◆ SleepMode

enum class board::SleepMode : uint8_t

strong

Defines all available sleep modes for ATmega328P.

Enumerator
IDLE	In this mode, CPU is stopped but all other peripherals and interrupts work normally. In this mode, current consumption is reduced to about 25% of active mode consumption.
ADC_NOISE_REDUCTION	In this mode, CPU is stopped but other peripherals and interrupts work normally, except IO. This mode is actually very similar to `IDLE`.
POWER_DOWN	In this mode, everything is stopped (including oscillator) but external interrupts, USI start condition (if enabled) and Watchdog Timer (if enabled). This is lowest current consumption mode, typically a few uA, depending on other factors (voltage, watchdog enabled or not). Waking up from this mode may take significant time until internal oscillator is restarted and stabilized; refer to datasheet for more detailed data (look for `Start-up times`).
POWER_SAVE	This mode is exactly the same `POWER_DOWN`.
STANDBY	This mode is exactly the same `POWER_DOWN`.
EXTENDED_STANDBY	This mode is exactly the same `POWER_SAVE`.

Definition at line 219 of file attiny_x5.h.

Function Documentation

◆ init()

static void board::init ( )

inlinestatic

Performs special initialization for ATtinyX5, actually nothing at all.

This must be called first in your main() function, even before sei(). In general you should ALWAYS call this function at the beginning of your main() even if you know it will not do anything; this will prevent strange behaviors when you want to port your code to another MCU target for which init() does perform important initialization, e.g. ATmega32u4 (Arduino LEONARDO).
