Small servo library for Arduino

This library is contained in the Arduino SevoEasing library.

• Comparable to Adafruit_TiCoServo library.
• No problems with servo twitching.
• Enables use of NeoPixels, SoftwareSerial, and DmxSimple together with servos in the same Arduino sketch.
• LightweightServo implementation only for pin 9 and 10 of Arduino Uno, Nano etc..
• Only timer1 hardware and no interrupts or other overhead used.
• Provides auto initialization.
• Supports F_CPU of 16, 8, 4, 2, 1 MHz.
• Save up to 600 bytes program size / 40 bytes RAM including auto initialization compared to Arduino Servo library.
• 8 bytes for each call to write9() or write10().

Usage

As simple as this:

#include "LightweightServo.hpp"

void setup() {
    // no initialization required for LightweightServo :-)
    // or use manual initialization (and compiler macro "DISABLE_SERVO_TIMER_AUTO_INITIALIZE") to save additional 60 bytes program memory
    // initLightweightServoPin9();
}

void loop() {
    write9(0);
    delay(1000);
    write9(180);
    delay(1000);
}

API

Compile options / macros for this library

To customize the library to different requirements, there are some compile options / macros available. Most macros must be defined in your program before the line #include <LightweightServo.hpp> to take effect. Modify them by enabling / disabling them, or change the values if applicable.
