Arduino - FastPin

This library provide a quick way for digital port manipulation - an alternative to pinMode, digitalWrite and digitalRead - where speed is crucial.

This is FAST pin.

Installation

Copy FastPin folder to Arduino library folder

Usage

• FastPin(byte id, bool isOutput = false, bool isHigh = false) constructor, initialize FastPin object with id of the pin and initial states (optional).
• void changePin(byte id, bool isOutput = false, bool isHigh = false) change pin.
• inline void input() equavilent to pinMode(pinId, INPUT).
• inline void output() equavilent to pinMode(pinId, OUTPUT).
• inline void high() equavilent to digitalWrite(pinId, HIGH).
• inline void low() equavilent to digitalWrite(pinId, LOW).
• inline byte read() equavilent to digitalRead(pinId).
• byte pinId() const get id of the pin.
• byte bitmask() const get bitmask of the pin, is used with DDR, PORT and PIN.
• volatile byte * ddr() const get DDR register of the pin.
• volatile byte * port() const get PORT register of the pin.
• volatile byte * pin() const get PIN register of the pin.
