Saving RFID Data

[mister_e]

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

Endurance
Internally, a FRAM operates with a read and restore
mechanism. Therefore, endurance cycles are applied
for each read or write cycle. The FRAM architecture
is based on an array of rows and columns. Rows are
defined by A8-A2. Each access causes an endurance
cycle for a row. Endurance is virtually unlimited. At
3000 accesses per second to the same segment, it will
take more than 10 years to reach the endurance limit.

not bad

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

Have you opened your PicBasicPro manual since you bought PicBasicPro?
What do you think the HEX2 does FOR you?
Take the HEX2 out of your HSEROUT and you'll get raw data.

Hi

Yes I read the book and i now that hex is to convert decimal in hex !
I think i have a serial problem i have read more rfid chips and i receive always the same serial.

Thank you

Hi

Yes I now what is happen the rfid send ascii,the pic receive the ascii and convert all the characters in decimal values 0 is 30 ,4 is 34 and so on.
Than I have more than 8 bytes I have 16 bytes.
I must now convert the decimals in hex,while i need hex data.

I try with hex but dont work!

Re-Read Post #16...then refer to your PBP on the proper use of SERIN/SEROUT/(etc) available modifiers and you WILL have your answer. I understand what you want, but I'm not going to give you the answer you need because you have all of the resources you need to get that answer...and you might learn something.
