I created a simple external memory interface/static memory controller.  Because of some HW limitations, it's not a full bus interface but can be used for interfacing with parallel LCDs.

ported Adafruit's sensor framework and TSL2561 (luminosity sensor) lib to the Due:

The AccelStepper library works beautifully with the Due. (Using step/dir based driver board.)

Desc:
High performance Non-Blocking (or blocking if desired).
Stepper library written in C++

Developmental Assets:
Very well documented.

Library:  pwm01.h
Description:  A clean alternate approach for setting up unique PWM frequencies from within a sketch, for any or all PWM pins.  The trick is to utilize the two PWM clocks (CLKA & CLKB) provided by the SAM3X8E chip.

I wrote and enclosed a library (pwm01.h).  It includes 4 user functions to:  1) setup PWM resolution, 2) setup PWM pin, frequency & pick clock, 3) write duty cycle, and 4) stop PWM.  See example code for usage:

Code: [Select]
#include "C:\Programs\arduino-1.5.1r2\hardware\arduino\sam\libraries\Pwm01\pwm01.h"

void setup()
{
   uint32_t  pwm_duty = 32767;
   uint32_t  pwm_freq1 = 2;  
   uint32_t  pwm_freq2 = 5000;

   // Set PWM Resolution
   pwm_set_resolution(16);  

   // Setup PWM Once (Up to two unique frequencies allowed
   //-----------------------------------------------------    
   pwm_setup( 6, pwm_freq1, 1);  // Pin 6 freq set to "pwm_freq1" on clock A
   pwm_setup( 7, pwm_freq2, 2);  // Pin 7 freq set to "pwm_freq2" on clock B
   pwm_setup( 8, pwm_freq2, 2);  // Pin 8 freq set to "pwm_freq2" on clock B
   pwm_setup( 9, pwm_freq2, 2);  // Pin 9 freq set to "pwm_freq2" on clock B
     
   // Write PWM Duty Cycle Anytime After PWM Setup
   //-----------------------------------------------------    
   pwm_write_duty( 6, pwm_duty );  // 50% duty cycle on Pin 6
   pwm_write_duty( 7, pwm_duty );  // 50% duty cycle on Pin 7
   pwm_write_duty( 8, pwm_duty );  // 50% duty cycle on Pin 8
   pwm_write_duty( 9, pwm_duty );  // 50% duty cycle on Pin 9

   delay(30000);  // 30sec Delay; PWM signal will still stream
       
   // Force PWM Stop On All Pins
   //-----------------------------    
   pwm_stop( 6 );
   pwm_stop( 7 );
   pwm_stop( 8 );
   pwm_stop( 9 );
}

void loop()
{  
}



The pwm01.h library and example code were tested in IDE 1.5.1r2.  Additional notes on this library:
- Applies to Arduino-Due board, PWM pins 6, 7, 8 & 9.
- Libary Does not operate on the TIO pins.
- Unique frequencies set via PWM Clock-A ("CLKA") and Clock-B ("CLKB")
 Therefore, up to two unique frequencies allowed.
- Set max duty cycle counts (pwm_max_duty_Ncount) equal to 255 per Arduino approach.  
 This value is best SUITED for low frequency applications (2hz to 40,000hz) such as
 PWM motor drivers, 38khz infrared transmitters, etc.
- Future library versions will address high frequency applications.
- Arduino's "wiring_analog.c" function was very helpful in this effort.

Hi!
As i like libraries, i have done one for Timers on the Arduino DUE.

You can check it out here: https://github.com/ivanseidel/DueTimer

All 6 timers are fully implemented, and ready to play with...
Arduino DueTimer | https://github.com/ivanseidel/DueTimer
Arduino Thread | https://github.com/ivanseidel/ArduinoThread

I made a (very basic) library to interface with the FTDI Vdrive2 module. Uses TX1/RX1 for communication with the Vdrive2 and TX0/RX0 to send the responses to the Serial Monitor.

https://github.com/prphntm63/VDRIVE2.git

Improvements welcome ;)

I can confirm that the Xbee Library works on DUE.  I ported over my code and tested last night.

I have merged all the features of my timer library with his. This is a great timer library, and we would love feedback for any features that people would like to see.

The Time library has been updated for compatibility with Arduino Due.

http://playground.arduino.cc/Code/Time

A Due-specific example was added, using Markus Lange's rtc_clock library to access the Due's on-chip RTC.

What on-chip RTC? I just built a DS1307 project for Arduino Mini; does the Arduino Due have an internal RTC so a chip like DS1307 is not needed?
I run Xubuntu Linux as my only computer operating system!
Windows does not run here; Only

Due does have an on-chip RTC.  The way the reset signals are wired makes it less useful for many projects, but there is indeed a RTC on the chip.

For more info, please download the new version of the Time library and look at its TimeArduinoDue example.  You'll also need Markus's rtc_clock libary.  Again, see the comments in TimeArduinoDue for more info.

May I ask you how I can use your file? I cannot include any library from out side. Is there anyway to run within one file? I would like to use a timer and change the REG by Serial Monitor.
