 /*
 * Created by: Cheng Saetern
 * This example is meant to demonstrate the ability to adjust pwm frequency and/or  
 * resolution for Arduino Nano/Uno pin 9 and 10 using function setPWM16(uint8_t prescaler, unsigned int resolution).
 * Equation for fast pwm frequency = frequency of MPU(16Mhz)/prescaler/resolution
 * F_PWM = 16000000/prescaler/resolution.
 * prescaler argument value MUST be between 1-5, representing 1,8,64,256,1024 respectively. 
 * resolution MUST be a value from 0-65535.

 /********************************************************************
 This is a "Fast PCD8544 Library". It is designed to be used with
 Nokia 5110 type of display, driven by the PCD8544 controller.
 This library uses hardware SPI of your Arduino microcontroller,
 and does not supprt 'software SPI' mode.

 // It is very important to wire the LCD correctly. 
 // The following is the default wiring configuration for an Atmega168/328 based Arduino:
 // PIN_DC    D8 
 // PIN_RESET D9 
 // PIN_SCE   D10 
 // PIN_SDIN  D11 
 // PIN_SCLK  D13 
 // You may change pins DC, Reset and SCE to map them to different pins on your Arduino board. 
 // Please keep SDIN and SCLK connected to your Arduino's MOSI and SCK (hardware SPI) pins.
 // You can remap the LCD control pins by changing the following '#define' values:
 // Please refer to the pin/port mapping for your Arduino device:
 // http://arduino.cc/en/Hacking/PinMapping168
 // http://arduino.cc/en/Hacking/PinMapping2560
 // Pins labeled Px (PB, PC, etc.) stand for PORTx.
 // The current version of this library only allows the use of one port for the control pins.
 // Pins are mapped in binary order. Valid values are 0x01, 0x02, 0x04, 0x08, 0x10, 0x20, 0x40, 0x80.
 // Px0 is the LSB pin of the port, which in turn is represented by the hexadecimal number 0x01. 
 // Px7 is the MSB pin of the port, which in turn is represented by the hexadecimal number 0x80.
 // This is the port where the LCD is connected.

 #define PIN_RESET			0x08	// D3
 #define PIN_CE				0x10	// D4
