Topic: Arduino Due libraries (official and 3rd party) (Read 259749 times) previous topic - next topic


Sorry for late reply - been working a lot lately. There is a README file added now. It explains how to "deactivate" the standard serial handling in Arduino. However, I think commenting out the old U(S)ARTClass objects are only necessary if you need to save space and never call e.g. Serial1.begin() after calling the begin() of DmaSerial.

About limitations. There are some todos marked in the code, e.g. supporting other confs than 8N1.

Usage is quite simple..

Outside loop() and setup():

#include "DmaSerial.h"

DmaSerial dma_serial  = DmaSerial((Uart*)USART0, ID_USART0);

USART0 is Serial1, USART1 is Serial2...

In setup():


In loop() or where you want to use it:

dma_serial.put("THIS IS A TEST!\n");
dma_serial.putln("THIS IS ALSO A TES!");

uint8_t buffer[32];

dma_serial.get(buffer, 32);

Sorry for the sloppy explanation.. Will include a proper example sketch in the future..



i try to load a lot of my working 2560 Mega projects on a Due.
The actual Due IDE is 1.5.8. If i select a Mega it compiles.
If i select a Due (programming port)  a lot of errors happen...
With an I2C bus:
Code: [Select]
avr/io.h: No such file or directory
 #include <avr/io.h>

or if i use a clock:
Code: [Select]
Arduino: 1.5.8 (Linux), Board: "Arduino Due (Programming Port)"

Build options changed, rebuilding all

Is there something wrong with my installation or are the Due-libraries still weak?
Is there no central Due support???


Finally succeeded to modified Adafruit RGB panel library for 16x32 rgb panel to suit arduino due.


I found it at here and it worked : https://codeload.github.com/enternoescape/Arduino-IRremote-Due/zip/master


how i can interface arduino due with HC05 bluetooth module.....
i was doing but there was no response with due....


The MIFARE MFRC522 library works properly with arduino due.
The SPI ports have to be used for interfacing.

I have created MIDI USB Library for Arduino Due.



How to transform a library for arduino DUE?
I want use a library that it is for operate with matrices, but it is not working for Arduino Due. What I should change in the library for use the library in the Due?

These is the librery:




I need to have the softwareserial.h or similar to run on a Due for a student project.
I have located 3 serial ports on the Due. Pls. advice: How do I get these ports up and running?

Regards, Steenoluf

Just got a DUE bord, and tried to compile. error can not find delay.h it is the _delay_ms() that I need.
Eny idea how I can work around it? Got IDE 1.6.4

Is there an easy way to change the code , so it will have different code when I want to run it on DUE and nano.
Maybe something like this, but for the delay.h

#if defined(ARDUINO) && ARDUINO >= 100
#include "Arduino.h"
#include "WProgram.h"

I guess I need to put in someting else, but this might be a sceleton I can use. If some got what I need to put in it will help.


First release of the RTC Library for the Arduino Due.

2 examples included.

I would call it final for the moment.

And on github: https://github.com/MarkusLange/Arduino-Due-RTC-Library

I hope the library is self explaining.


Update new library with unixtime and compilertime support

Update Version 1.2 now support for Date & Time in one operation for BKM.

And some changes all in the changelog

Update Version 1.3 now unixtime with timezone support with Example for it, for tevroc

Update Version 1.4 now support for geman timezone with Summertime.

Update Version 1.5 some changes in the Summertime Sketch, and updates at this point only on git

Update Version 1.6 added rtc_clock.timing to detect when the time was set in summer- or wintertime
(mostly helpfully for the german member)

Update Version 1.7 added rtc_clock.date_already_set() to proof if date is allready set, to prevent setting time again for Paul Stoffregen

Update Version 1.8 added rtc_clock.set_clock() to set __Time__,__Date__ in one line fixed bug in unixtime() and summertime() thanks to Paul Stoffregen for the hint
Hi, what are the pines to conect in DUE?


I tested the ethernet library and it works with one minor difference. Do not set D10 as an OUTPUT in setup.

I tested these playground sketches and all work with the Due.


I just tested the Pololu AHRS (9DOF) library, and it works.
I'm using it with the 10DOF board from Adafruit.


A question for garygrewal: I looked through the library set you pointed to and didn't see anything related to USB MIDI, did i miss it? It looked like there was just the usual HID, keyboard, etc., but nothing I could see related to MIDI. Was I looking at the wrong branch (I used the URL you posted), or are the methods buried somewhere else in the library and I just missed it?

I'm very interested in trying to use such a library with a project I working on, so any help in finding your work is greatly appreciated.

The Adafruit 16 channel PWM/servo library works with the Due. If you use the breakout board, insure you use the new SDA and SCL pins (Wire1) next to the AREF pin.
