Hi,

I’m trying to read a temperature sensor from ON Semiconductor using the Simultaneous Rfid Tag Reader

I can read all the data from bank 0 to 3 without problems

To read the temperature there is a procedure to follows:

  • request (set bank3, address E0, length 0 and mask empty) with 2.5ms continuous wave output

  • reading (set bank0 , address E0)

but I can have a correct data

Have you never try to read this kind of rfid sensor ?

have you any suggestion?

thanks

Fausto

Never tried, but in order to read/write on a specific address with a specific length, I have modified the original Sparkfun library before. There is a call and example to handle that for user bank/Tid bank. Take the latest version from https://github.com/paulvha/ThingMagic/t … ib_special.

However, to keep the RFID signal on for 2.5mS, the full MercuryAPI (Linux or Windows) has an option :/reader/gen2/writeReplyTimeout which is not in the scaled-down version of Sparkfun. But you can still try and see what happens.

Thanks Paul,

I’ll try with your library but I was already able to read specific addres from one of the four banks

The problems is that, for the documentation of this Rfid sensor, I need to send a “standard SELECT command” to an addres of the bank 3 and then a “standard READ command” to an addres of the bank 0: if I try to use the read command also for the first part I don’t have the correct answer from the sensor

p.s. Just few minutes ago I found more comments from others who have attempted the acquisition and they said there is no this possibilities with the Sparkfun Rfid Tag Reader…
