My chip have the Pin E2 to VCC thats mean The Device Adress is :10101000 for Write and

Ok, is it the serial part that's not working?
The EEPROM is returning bad data?
Is the program running?
Which is it?
Think simple...build it up...
Make the LED blink...Show some data on the LED...Make the HSEROUT work
I know you don't have an LED here...maybe you should put one there eh?
Hi,
im so Stupid I forgott something important ,on the Chip I forgott to set WC Low,and i use now more pause to write and to read data.
Now is working but what i don't understand ,on the 24C02 i dont set wc too and has working!
What you think is this a good Idea to use 24c chips to store rfid tags data,the chips have a 1000.000 write cyclus.
When I write on one day Double (Write and Erase) I have then on one Day maybe 4 Write Cycle.
Thank You

depending the warranty and service you want to provide... but you could use F-RAM instead

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
Thank You Mister_e
The RFID Data will be stored on the 24C and then Send trough GPRS Transmitter to Central Unit.
If all is ok the data will be Erased.
And I have again free space for new data.

Ok
All work fine now but :-)
I receive the data from rfid reader in ascii i use to receive data on the pic this:
Serin2 PortD.0,84,[Wait("E0") ,Daten[6],Daten[5],Daten[4],Daten[3],Daten[2],Daten[1],Daten[0]]
Daten[7] = $E0
but when I send to pc and to LCD with this
HSEROUT [hex2 Daten[7],hex2 Daten[6],hex2 Daten[5],hex2 Daten[4],hex2 Daten[3],hex2 Daten[2],hex2 Daten[1],hex2 Daten[0],13,10]
Lcdout $fe,$80,hex2 Daten[7],hex2 Daten[6],hex2 Daten[5],hex2 Daten[4],hex2 Daten[3],hex2 Daten[2],hex2 Daten[1],hex2 Daten[0]
I receive on the PC and on the LCD this : E030343031303030
I don't have found the way to convert to hex I need Hex on PC and on LCD.
Thanks
Regards Pesti
