Hi, I`m Dan Park
I have some questions.
We are NFC Forum member and NFC Forum test laboratory.
So, I bought TRF7970AEVM/RF430FRL152HEVM last week.
Becuase we need NFC reference sample.
Do you know how to configure your test sample with our testing tool(Protocol capture tool).
We don`t want to develop NFC device, but want to test only NFC role such as Card emulation, R/W and P2P mode.
I`m looking forward to your quick response.
Hi Dan,
Thanks for reaching out about this. We do have example firmware+hardware designed with NFC Forum standards in mind, but the TRF7970AEVM is not a platform which supports this. The MCU on the TRF7970AEVM is too small to run a fully featured NFC stack.
We have developed our latest firmware for use with our DLP-7970ABP BoosterPack which is the BoosterPack for the TRF7970A. The firmware itself was developed on an MSP430F5529, and you can use the MSP-EXP430F5529LP to interface with the BoosterPack to run our firmware example.
This bundle can be acquired from the following link: https://store.ti.com/nfclink-bndl.aspx
I will note that the BoosterPack setup runs at 3.3V by default so the output power over RF of the TRF7970A will be limited by this. You can get around this by wiring in connections between the boards without plugging them together and then sourcing 5V to the BoosterPack and use the GUI (will explain in a moment) to change the TRF7970A to 5V operation.
Alternative you could get a more expensive evaluation solution which uses the TRF7970ATB Eval Module and the MSP430F5529 Experimenter's board. This setup runs the TRF7970ATB at 5V at all times due to a boost regulator on the TRF7970ATB.
You can purchase the TRF7970ATB at: https://store.ti.com/TRF7970ATB.aspx
And the Experimenter's board at: https://store.ti.com/MSP-EXP430F5529-MSP430F5529-USB-Experimenters-Board-P2413.aspx
Regarding the firmware, our latest NFC stack release has support for Peer to Peer, Card Emulation, and Reader/Writer modes as well as NFC Forum compliance settings which allow for the various required configurations for testing.
The latest version of this stack can be found at: http://www.ti.com/lit/zip/sloa227
This firmware includes a GUI which allows for the easy configuration of our device for each NFC mode:
The orange boxes allow you to choose different NFC operating modes and the appropriate technology types and bitrates
The red boxes give you configuration settings, such as the 3V vs 5V mode I mentioned above, and the NFC Forum Compliance Configuration pane which allows you to set a number of variables that can vary during compliance testing for P2P and Reader/Writer.
We also wrote app notes for each NFC operating mode which you can reference:
Regarding the RF430FRL152HEVM, what do you wish to test with it? It is a Type 5/V tag, and it doesn't natively support NDEF messages though it is possible that a patch could be applied in order to do so. Do you want to test it for NDEF contents?
Another tag platform we have used with the NFC Forum tests is the RF430CL330H. It is a dynamic NFC tag which uses ISO14443B/NFC Forum Type 4B and it only does NDEF messages. I think for testing purposes specifically we used the RF430CL330HTB along with an MSP430FR5739 LaunchPad. I'd have to check for more details on that if this is something you are interested in.
If you want to discuss any of this in a more private channel, you can send me a friend request on E2E and then we could have a Private Message thread.
