Other Parts Discussed in Thread: TRF7970A I have built a board with the TRF7970A NFC transceiver IC. It is used in SPI mode with SS. It uses a trace antenna much like the one on the EVM board but I can't get it to work. The board is powered with 3.3V…
Hi Michael,
The P2P example in TivaWare does not include Reader/Writer functionality at all, so it is not a matter of modifying some sections. However, the firmware basis for that P2P project has been updated on the MSP430 platform to include Reader…
Hey there,
I got the initial information from an email.
I would still like to have the design files. The design is different than just the IoT Gateway.
The links to the Hardware and Software guides are still active, but design files are missing…
Hello John,
1) Yes.
2) Yes, 4064.TIDM_NFC_RW_DLP7970ABP_SCHEMATIC.pdf
3) See above, that is all I can provide.
4) Yes, it is used to handle the emulation and debug for the device. This allows for the programming over USB without needing an MSP…
Kaka,
It is possible to operate purely passive. See the attached document. It is important to note that the phone/tablet transceivers do differ in field strength and the length of the RF "field on" time during the polling cycle. The performance of the…

Equation 4
The velocity of gas medium is directly proportional to (1/Tup - 1/Tdown) = △T/(Tup*Tdown)
Does it mean the delay is cancelled on numerator but gets error on the denominator?
Hi Ralph,
thx for your reply.
Now I read nfc data with common app "TagInfo" by NXP.
The result of full scan tab is:
** TagInfo scan (version 4.23) 2018-09-11 18:52:37 ** Report Type: External

Newbie here - yet oldie in other fields. Hoping you guys can help a simpleton understand some basic concepts.
I have researched the old RFID readers TI S4100 is designed around the S6700 Multi-Protocol Transceiver IC, an integrated HF reader system…
Newbie here - yet oldie in other fields. Hoping you guys can help a simpleton understand some basic concepts and make suggestions for component add-on's for my TRF7970- EVM Evaluation board and complete testing system.

Utsav -
discussion about GUI commands starts around slide 27 - hope this helps you out.

in case you want it to be automatic (standalone) - we do also have this TI design available - just FYI
