Arduino - 2.2 tft shield - w5100 shield [SOLVED]

[Maciej Kozyra]

Hi Fernando.
I read posts about tft and w5100 but to be sure if you have new 2.2 tft sheld and ethernet shield w5100 with sd card on it you have to:
1. Remove pins 50, 51, 52, 53 from tft shield
2. remove pins 10, 11,12 and 13 from ethernet shield W5100
3. enabled pin 4 in the code (#define USE_PIN_4_FOR_SD_CARD)
right?

Hi!

You should NOT remove pins from ethernet shield. Just leave this pins disconnected then make a bridge as shown in this image.

Best regards.

Ok than, to sum up this procedure:
If you use arduino mega tft shield ver. 2.2, ethernet shield w5100 and sd card on this ethernet shield:
1 Remove pins 50, 51, 52, 53 from tft shield
2. Disconnect pins 10, 11,12 and 13 between arduino mega and ethernet shield W5100
3. Connect pin 53 from arduino mega with pin 10 on the ethernet shield
4. enabled pin 4 in the code (#define USE_PIN_4_FOR_SD_CARD)

and job is done to connect ferduino with internet (of course after uploading software to arduino and connecting at least rtc ds3231 to arduino too)?

Best regards

More or less because you have to change IP address, gateway e credentials for web interface on code.

Also a PCF8575 is required otherwise you will get a white screen.

[Maciej Kozyra]

Rtc and PCF8575 in the proper version must be connected.
But if I want to join your web interface I have to change user name and password only do I? In your the latest software I don't have to change IP and gateway adress right?

Hi!

The instructions about web interface are here please check it.

Best regards.

In my case I didn't have to change the rest of web parameters. I had problem with unstable connetion but the problem was router. W5100 didn't want to cooperate with it. Connecting to diffrent router solved problem.

Thank you Fernando.

Glad to hear!
