Thanks. DUE version would be also good.

Yes, the Author fixed the links to the website, but not for the downloads. The Author is still active here in the forum, but is not answering forum messages, website comments or emails.

So, the only hope is that maybe another user has that download stuff and can upload it in this forum.

@johnfraiser

Please, can you post the whole code, because it's not available anymore on the original website (all Download-Links are dead). And the author is not answering requests via email or forum account.

Thanks in advanced.
5  Using Arduino / Project Guidance / Arduino DUE + i2C: massively problems with LCD LiquidCrystal LCD + Compass on: August 16, 2014, 02:56:18 am
It seems that the DUE has massively problems with the I2C library.

First I give it up to use a i2c compass (HMC 5883) and now also the LuqidCrystal LCD (SaintSmart) is not working.


Code:
#include <LiquidCrystal_I2C.h>

void setup(){}

void loop() {}

Error Message: libraries/LiquidCrystal_I2C/I2CIO.cpp:35: fatal error: ../Wire/Wire.h: No such file or directory. compilation terminated.

Code:
#include <Wire.h>

#include <LiquidCrystal_I2C.h>

void setup(){}

void loop() {}

Error Message: libraries/LiquidCrystal_I2C/LiquidCrystal.cpp: In member function 'virtual void LiquidCrystal::setBacklight(uint8_t)': libraries/LiquidCrystal_I2C/LiquidCrystal.cpp:173: error: expected primary-expression before ')' token


Code:
// LCD Demo
#include <Wire.h>
#include <LCD.h>
#include <LiquidCrystal_I2C.h>
....

Error Message: LiquidCrystalSaintsmart16_2_Demo.ino: In function 'void setup()':
LiquidCrystalSaintsmart16_2_Demo:207: error: 'PSTR' was not declared in this scope
LiquidCrystalSaintsmart16_2_Demo:209: error: 'fdevopen' was not declared in this scope


Hint:All is working fine... if I use an UNO Board.


Has anybody got it to work with a DUE Board?

Oha, I've seen the nice "Udoo" Board with Arduino, Linux and Android in it.

There you have the same problem with the USB Ports, ... but you can store the whole "System Image on a Micro SDCard", so you can give it to other users very easily (no Sketch upload, no python script handling, no configuration).

This is also the big thing with the Raspberry Pi.

I will give it a try.

Thanks,  I've seen it before I've made this post, but this is a difficult phyton solution, not an easy out-of-the-box sketch solution smiley

And I don't know if the USB Mouse is also working.
The USB part of the Yun is physically only connected to the Linux part, so you can't use any USB connected device on the Yun in a sketch (directly).

Thanks, but I know this. But maybe, ... in the future ... a new Image can handle this.

The Arduino Yun is a nice project, because of integrated Ethernet + USB Host.

I'm using USB Mouse + USB Keyboard a lot, but for the old Arduino Boards you need a USB Shiled... and if you need Internet, also an Ethernet shield.

So, I was hoping now I need only the Arduino Yun, and no more the USB and Ethernet Shields.

But... it seems that simple USB devices the Adruino Yun can not handle and read the data via sketch ( I know to install python,  and other stuff, but this is not "out of the box").

... so, it would be nice for a Yun Image upgrade, to support access for USB Mouse + Keyboard via an Arduino "sketch".

(UDP Server/Client would be also nice smiley

Thanks.

11  International / Deutsch / Re: Arduino Mega: nur 1 von 4 UARTS (Serial 1-4) funktioniert, warum? on: June 14, 2013, 12:19:33 pm
Ich verstehs auch net.

Vielleicht liegts auch an dem Bluetooth Shield (Itead V2.2). Keine Ahnung. Hatte über Probleme mit dem Mega bei Google gelesen und dachte ich hätte das gleiche Problem.

Muss ich alles mal durchtesten.
12  International / Deutsch / Re: Arduino Mega: nur 1 von 4 UARTS (Serial 1-4) funktioniert, warum? on: June 14, 2013, 11:29:56 am
Hmmm...

Ich habe das hier mal gemacht:
Code:
void setup() {
  // initialize both serial ports:
  Serial.begin(38400);
  Serial1.begin(38400);
  Serial2.begin(38400);
  Serial3.begin(38400);
}

void loop() {
 
  Serial1.write(0x41);
 
  delay(200);
 
  if (Serial2.available()) {
    int inByte = Serial2.read();
    Serial2.write(inByte);
  } 
  delay(200);
 
 
  if (Serial3.available()) {
    int inByte = Serial3.read();
    Serial3.write(inByte);
  }   
  delay(200);
 
 
   if (Serial.available()) {
    int inByte = Serial.read();
    Serial.write(inByte);
  }   
 
  delay(200);
}

Und Brücken gesteckt TX1->RX2 | TX2->RX3 |  TX3->RX0

Funktioniert.


Kann es sein, dass es an meinen gesetzten Interrupts liegt? :

Code:
// * Interrupt *
 TCCR1A = 0;  
 TCCR1B = (1<<CS10); 
 TIMSK1 = (1<<OCIE1A);



ISR(TIMER1_CAPT_vect) {         
   
}


ISR(TIMER1_COMPA_vect) {
       
    long time = micros();           
   
   OCR1A += 5000-time; 
}

Laut dieser Aussage hat der Mega 2560 4 "hardware serial, Serial1, Serial2 or Serial3 on Arduino mega2560":
http://embeddedcomputing.weebly.com/tutorial-2-playing-with-serial-ports.html


Du kannst ja mal probieren ein Byte an Serial1 zu senden, und mit Brücken jeweils TX/RX der Serial1,Serial2, Serial3 zu überbrücken... und zum Schluss dann von Serial3.TX => Serial.RX Pin, dann im Seriellen Monitor das gesendete Byte anzeigen lassen.

Serial.begin(38400);     
Serial1.begin(38400);
Serial2.begin(38400);           
Serial3.begin(38400);   


Das wird nicht funktionieren... weil bereits schon Serial1 oder Serial2 nicht available() sein wird.



14  International / Deutsch / Arduino Mega: nur 1 von 4 UARTS (Serial 1-4) funktioniert, warum? on: June 14, 2013, 04:51:11 am
Hallo,

Seit ca. 7 Stunden wühle ich mich bei Google durch, und das Internet ist voll von Berichten über nicht funktionierende Serials des Arduino Mega.

Wenn man nur 1 der 4 mit SerialX.begin(X) initialisiert, funktioniert alles problemlos. Dabei ist es vollkommen egal ob Serial1, Serial3 usw.
Aber wenn man einen 2. versucht zu initialisieren, dann bekommt man mit SerialX.available() immer ein negatives Ergebnis.

Kennt irgendjemand eine Lösung wie man diesen Bug umgehen kann?

Welche "funktionierende" Alternative existiert zu dem defekten Arduino Mega?


PS.: mit dem Arduino DUE scheint das selbe Problem zu existieren, jedenfalls kann ich nur 1 UART gleichzeitig nutzen. Ärgerlich. Da hat man 2 Boards mit 4 Uarts...  doch sind genauso limitiert wie ein uralter Arduino Duemilanove smiley
15  International / Deutsch / Re: Arduino Pro mini 3.3v 8 Mhz, ist 132000 Baud irgendwie möglich? on: June 07, 2013, 03:08:18 pm
Ok, danke.


Bei "UBRR0L  = 15" bekomme ich keine Fehlermeldung, das ist schon mal gut.

Dann werde ich wohl es mal mit dem Pro Micro 3.3V / 8 Mhz probieren... vielleicht klappt es ja dann doch mit dem Serial1. Wer weiss smiley
Werde dann davon berichten.
