121  Using Arduino / Networking, Protocols, and Devices / Re: W5200 Module on: May 15, 2012, 05:44:09 pm
Hi I have been using it for a while now.
I have even implemented some of the 1.0.1 code into the libraries from wiznet in order to use the DHCP maintain function.
I will hopefully begin work on the shield to start with during the summer

Product Webpage is here
http://www.wiznettechnology.com/sub_modules/en/product/Product_Detail.asp?cate1=5&cate2=38&cate3=0&pid=1144#tab

The W5200 has support for 8 simultaneous sockets vs w5100s 4 sockets
W5200 has Powerdown mode and wake on LAN
W5200 is a 48 pin package
W5200 has Internal 32Kbytes Memory for Tx/Rx Buffers vs 16KB for W5100.

From my testing it appears to gain a DHCP lease faster then the w5100 too.

Replacing the dated w5100 controller on the ethernet shield and arduino ethernet with the w5200 which supports sleep mode for one and is an overall better chip

Sorry I didn't reply to anything here guys. Life is chaos, but good to see everyone likes the new chip.  The only thing that would be awesome would be an arduino ethernet with the W5200 onboard instead of a w5100 and the same for the ethernet shield.
When I get the project I'm working on out the door I think that is what I'm gonna do.
125  Using Arduino / Storage / SD to Progmem on: April 07, 2012, 12:09:27 pm
Hi

I have a data logging application that stores data in a text file as CSV, I then want to send that data using http://arduino.cc/forum/index.php/topic,93502.msg707104.html#msg707104
Can I transfer the text file into progmem from the SD card so that I can send the file in one go and avoid SPI issues?
I am using a mega2560 so space isn't an issue.

Hi,
What is the most reliable and efficient method to send text files from my arduino over the internet/network to my computer?
127  Using Arduino / Networking, Protocols, and Devices / Re: W5200 Module on: April 06, 2012, 06:01:07 pm
I would just like to report back on these modules,
THEY ARE BRILLIANT, screw the ethernet shield, lower power consumption from what I have tried and faster DHCP pickup as well as cheaper and don't forget the power down option which I still need to implement/play with.

It turns out that if I set the SS pins for the SD.h lib and the Ethernet.h lib (4 and 10 respectively) then they don't work.  However if I don't mention anything in the setup they work fine.  And the oscilloscope confirms that all the selections seem to be done automatically.  Aaaaannnnddd everything works together.  smiley-lol
129  Using Arduino / Programming Questions / Re: Simultaneous SPI Devices on: April 05, 2012, 11:05:38 am
Hi
With just ethernet device plugged in I enabled the SS pin as an output even if i put it low it stops working, does the ethernet library control this because I had a look on an oscilloscope without mentioning the SS pin and it seemed to output 3.3V but drop it to low whenever there was communication between the two.

Hi,
I am trying to run an SD Card and the WIZ820io Ethernet interface on an Arduino Mega 2560
Both work separately but as soon as I add
Code:
pinMode(10, OUTPUT);
digitalWrite(10, LOW);
the ethernet interface stops working

I found it!
I had one of those Eureka moment thingys!  smiley-mr-green

in the Ports.h file
change
Code:
    uint8_t portNum;

    inline uint8_t digiPin() const
        { return portNum ? portNum + 3 : 18; }
    inline uint8_t digiPin2() const
        { return portNum ? portNum + 13 : 19; }
    inline uint8_t anaPin() const
        { return portNum - 1; }

to

Code:
    uint8_t portNum;

    inline uint8_t digiPin() const
        { return portNum ? portNum + 3 : 18; }
    inline uint8_t digiPin2() const
        { return portNum ? portNum + 53 : 19; }
    inline uint8_t anaPin() const
        { return portNum + 53; }

I have tried checking with an oscilloscope on the analogue pins when the sensor is plugged in and I don't seem to get anything as I normally would.

The hardware i2c channel works just fine on the mega, its the soft ones I am trying to use that don't seem to work
133  Using Arduino / Programming Questions / Soft SHT21 Libraries on Arduino Mega on: April 04, 2012, 05:48:39 am
Hi
I am using the following libraries and I am trying to get them working on an arduino mega
I am unsure how the pins would be mapped.

https://github.com/mrjonny2/PortsSHT21
The code worked on anything with an ATMega328
the code to use the library is;

Quote
#include <Wire.h>
#include <Ports.h>
#include <PortsSHT21.h>
#include <SHT2x.h>

//Define soft i2c channels for 3 sensors
  SHT21 hsensor2 (2); // pins A1 and D5 - Sensor 2
  SHT21 hsensor3 (3); // pins A2 and D6 - Sensor 3
  SHT21 hsensor4 (4); // pins A3 and D7 - Sensor 4

//define variables for temp data
  float h, t;
 

void setup()
{
        Wire.begin();
   Serial.begin(9600);
}

void loop()
{
   // Get data from first sensor hard I2C channel
    float hum1 = (SHT2x.GetHumidity());
    float temp1 = (SHT2x.GetTemperature());
    Serial.println("temp1");
    Serial.println(temp1);
 
  // Get data from second sensor soft I2C
  hsensor2.measure(SHT21::HUMI);
  hsensor2.measure(SHT21::TEMP);
  hsensor2.calculate(h, t);
    float hum2 = (h);
    float temp2 = (t);
    Serial.println("temp2");
    Serial.println(temp2);     
 
   // Get data from third sensor soft I2C
  hsensor3.measure(SHT21::HUMI);
  hsensor3.measure(SHT21::TEMP);
  hsensor3.calculate(h, t);
    float hum3 = (h);
    float temp3 = (t);
    Serial.println("temp3");
    Serial.println(temp3);     
     
     // Get data from fourth sensor soft I2C 
  hsensor4.measure(SHT21::HUMI);
  hsensor4.measure(SHT21::TEMP);
  hsensor4.calculate(h, t); 
    float hum4 = (h);
    float temp4 = (t);
    Serial.println("temp4");
    Serial.println(temp4);
    Serial.println("");
    Serial.println("");
    delay(500);
}

Hey,
So thats why the SD library kills my SRAM then.
Yes I have been looking into the Mega but the 1280 is an expensive chip.   
are there any other storage options that offer at least 4MB of memory that would not suck up SRAM?
135  Using Arduino / Programming Questions / Re: SD Card and Ethernet lead to avrdude: stk500_recv(): programmer is not respondin on: March 29, 2012, 05:04:51 pm
The serial print stuff is just there for bug testing, so would commenting it all out be beneficial to reducing ram?

Are there any alternative libraries that you know of that are more conservative towards SRAM?  Should I keep the sketch see below 29000 bytes because that is where the funny stuff seems to happen?

Is there anything else I could get rid of that you see as unnecessary? within the code? or a way to trim down the libraries?
