You should not use float to store the rfid codes, because of floating point format truncates some values and i wont work.

stere them as integers o byte values

I'm having problems with the EDB library using an AT24C1024 memory, first I create a db with some data, I read the data back to verify it was written correctly, and it was.

After i reset the arduino, the data from the two first registers of the database are corrupt, just the two first.

I would like to know if someone is having the same problem. I need some advice.

thanks

i'm appending a capture of five strings i saved to the database,
when I save them and read them back from the database they are like this:

T12345 F200 G200 H200 S1
T12345 F200 G200 H200 S1
T12345 F200 G200 H200 S1
T12345 F200 G200 H200 S1
T12345 F200 G200 H200 S1

after a reset the same strings read this:

T17 F0 G0 H8 S0
T2 F200 G200 H200 S1
T12345 F200 G200 H200 S1
T12345 F200 G200 H200 S1
T12345 F200 G200 H200 S1

Sure you can use up to 4 tcp/udp sockets, control several i/o lines and receive commands from serial or ethernet connection. You can implement your own command interpreter. It´s not hard to do.

If you need any help , Let me know, sure i can give you  some advice.

best regards

you will need the crystal for normal operation unless you set the atmega fuses to work with internal oscillator

I had the same problem, I figured out that the google server was refusing the connection, so i try with another ip from google, and it worked.

sure you can do what you say, just check the crystal frequency has to be the same
