2  International / Software / Re: como usar librerías?? on: August 20, 2014, 09:59:29 pm
Hola joselet.

La libreria VirtualWire fue creada en el 2009 muy probablemente con una IDE no actualizada como la IDE que estas utilizando. Ello te obliga a realizar los siguientes cambios:

-En el archivo VirtualWire.cpp reemplaza la linea 14: #include "WProgram.h" con #include "Arduino.h"
-En el archivo VirctualWire.h  reemplaza la linea 14: #include <wiring.h> con #include <wiring_private.h>.

Saludos,

.... Yo lo que si quisiera es un integrado que tenga muchas salidas/entradas bidirecionales para el detalle del cambio 3.3/5 asi se simplificarian los montajes... pero ni idea de como buscar algo asi

Hola Nomada. He utilizado con exito la siguiente tarjetita que tiene 4 entradas/4 salidas.

https://www.sparkfun.com/products/12009

Aprovecho para comentarte que  actualmente cada vez mas fabricantes (Sparkfun, Adafruit, etc.) vienen agregando el pin de 3.3 voltios en sus escudos de Arduino. La tendencia es disminuir el consumo de energia al adaptarse a microcontroladores como el SAM de Arduino Due. Saludos.

4  Products / Arduino Due / Problem finding COM device in Arduino DUE with 25V caps on: August 20, 2014, 02:46:13 pm
I just got a few new Arduino Due boards. All of them with 25 volts capacitors (SERIALS D000394XX) and I have noticed that it is necessary to press the erase and reset buttons everytime I need to load a sketch, otherwise I get the following:

Code:
Send auto-baud
Set binary mode
No device found on COMXX

Such a thing has never happened to me before using old Arduino Due boards with 16 volts caps.
Has anyone experience this lately?

Regards,

5  Development / Other Hardware Development / New MultiTech SocketModem Shield Arduino compatible on: August 11, 2014, 09:51:43 pm
I got today this SocketModem Shield for my MTSMC modem. It's an Arduino shield compatible board. It comes with the antenna, cable U.FL IPEX to SMA, a DC power adapter, European connectors and a dual small screwdriver. I haven't tried yet but planning to post about my tests with it.

Hello ecousin,

The tutorial that you linked is for AVR. Arduino Due is SAM. It's also a bit hard to tell you what could be happening with your project without the code or at least the main file. Regards,

fsimon,

Code:
//save value in two bytes
EEPROM.write(10, lowByte(sensorValue));
EEPROM.write(11, highByte(sensorValue));

Code:
//retrieve saved value
sensorValue = word(EEPROM.read(11), EEPROM.read(10));

I've been running the IDE 1.5.7 for a week without problems. I must say my Arduino libraries folder is always empty (I always like that way). If you want the same way, backup (copy-save in safe area of your hard drive) all your Arduino libraries and clean the folder located at:

Quote
C:\Users\YourName\Documents\Arduino\libraries

Then, try to compile again.

Hello mboroff,
Please, post the error messages. Most of the time they indicate a code line or library file reference like...

Hello An00bIS,

The EMAC library for Due remains very raw. You can download it with an sample sketch here:

https://github.com/elechouse/EMAC-DEMO/tree/master/EMAC

I tried to conform a work team about a year ago but this has not really been possible for a number of reasons. I also corroborated the library with a sample of a basic HTTP web server using lwIP TCP/IP stack (see reply#92) but that is not on github yet. Feel free to use the library 'as is' but again, it is raw and will work as a base for more developments. Regards,

p

AFAIK, yes. The libraries (TFT, Adafruit_ST7735 and Adafruit_GFX) were used from IDE 1.5.6-r2 dated Feb.21, 2014. By the way, have you a 1.77 and UNO?

It's hard to say but the TFT initialization is the key ingredient in the formula. Despite having experience working with TFTs with UNO, MEGA and DUE, I'm not a good connoisseur of the Arduino 1.77. In particular, the codes that I have provided to you run thoroughly with my Arduino UNO and Adafruit 1.8 TFT which are closest to yours. It could be anything what is causing your problem, from a broken wire to a corrupted IDE (without ruling out the possibility of a defective TFT). Right now the only thing I can think of is for you to contact support@arduino.com and depending on their answer, to contact your TFT's vendor for a replacement.

Let's try replacing the following line of code:

Quote
tft.initR(INITR_BLACKTAB);

with

Quote
tft.initG();

and also with

Quote
tft.initR(INITR_GREENTAB);

Hello Thorium234,
Green tag. Thank for the info. This meas that you have the new version of the LCD and that runs by default with the 1.5.X.

Given that the Arduino LCD TFT library is based on the Adafruit one, please, try the following test code (equivalent to my previous one) that I have prepared using the Adafruit library and let's see how it goes.
Notes:
-Use the Arduin IDE 1.5.6-r2.
-Use the last wiring I told you from: http://arduino.cc/en/Guide/TFTtoBoards#.UyWQNNyP4p0

Here the Adafruit test code:

Code:
#include <TFT.h>
#include <SPI.h>

#define sclk 13
#define mosi 11
#define cs   10
#define dc   9
#define rst  8

Adafruit_ST7735 tft = Adafruit_ST7735(cs, dc, mosi, sclk, rst);

void setup(void) {
 tft.initR(INITR_BLACKTAB);
}

void loop() {
  tft.fillScreen(ST7735_RED);
  delay(1000);
  tft.fillScreen(ST7735_GREEN);
  delay(1000);
  tft.fillScreen(ST7735_BLUE);
  delay(1000);
}
