Ethernet module [SOLVED]

[Simone Sandonati]

Hello
I want to connect this network adapter like this



I can not understand where to connect the pin SS in the arduino mega

[Fernando Garcia]

Hi!

SS is Select Slave goes to pin 53.

Best regards.

[Simone Sandonati]

but the 53-pin I am using it for the sd card

I could use a more different pin?

[Fernando Garcia]

Hi!

The SD card SHOULD be connected on pin 4 as explained in many topics here.

Best regards.

[Simone Sandonati]

OK, fine

but it would be possible to use another pin for the network card?

and leave the pin 53 for the sd card?

[Fernando Garcia]

Hi!

In fact is possible changing the code.

Use the pin 4 for SS because it can work in parallel with touch screen so, you will save a pin to another function.

In Ferduino tab, if do you have this variable uncommented:

Code: Select all

USE_PIN_53_FOR_SD_CARD

Only check if your code is like this:

Code: Select all

#ifdef USE_PIN_53_FOR_SD_CARD
const byte SelectSlave_ETH = 4;


If your version haven't the lines above change your code to:

Code: Select all

const byte ChipSelect_SD = 53;
const byte SelectSlave_ETH = 4;

Keeping the pins according to default code helps to upgrade when a new version is available. For it I told to connect the SD card to pin 4 and ethernet to pin 53.

Best regards.

so if instead of pin 4 in the Select Slave ETH you can for example use a free pin right?

Code: Select all

const byte ChipSelect_SD = 53;
const byte SelectSlave_ETH = (pin free);


thank you

[Fernando Garcia]

Yes, it's right but you will lose a pin that can be used to another function as I told.

This works because the ethernet library has been modified by you right?
because I have upgraded your library via IDE 1.6.9 and does not work anymore
if you get back your library back to work

[Fernando Garcia]

Hi!

Yes, it's a custom library.

Best regards.

[Simone Sandonati]

connected all right but with the small network adapter gives me:

please insert a SD Card





if you put the shield network card works well doing same links them

[Fernando Garcia]

Hi!

Use the codes for test to make the ethernet module and SD card to work separatelly. Then the example "Simple Web server running on SD card".

Maybe is needed change the speed on setup.

Code: Select all

while (!SD.begin(ChipSelect_SD, SPI_HALF_SPEED))

Best regards.

I found this article on the internet could be the problem that this network module does not work with the sd card

[Simone Sandonati]

It could be the problem ????

[Fernando Garcia]

Hi!

Can you make the tests suggested above and show me results first please?

Best regards.
