Using the TRF7970A EVM With PC GUI
2.4 ISO14443A Tab
The ISO14443A tab is used to perform Layer 3 and some Layer 4 operations on ISO14443A PICCs, up to
the stage at which transparent data is to be exchanged according to the ISO/IEC144443-4 standard.
2.4.1 Anticollision
In the TRF7970A EVM GUI, this command performs the anticollision loop as outlined in the
ISO/IEC14443-3 standard as outlined for one PICC (steps 1-5, flowchart for PCD). The TRF7970A EVM
firmware and GUI also have provisions for resolving a collision between two Type A PICCs by using a
special combination command (0xE6) and the Test tab. This section demonstrates the remaining steps
(6-10) for this operation from the previously mentioned flowchart that occur before the select command is
issued.
To perform anticollision loop on one tag using the GUI:
1. Select the radio button for anticollision
2. Click Set Protocol.
3. Place tag or transponder near enough to the TRF7970A EVM antenna to be read.
4. Click Execute.
Figure 20. Anticollision Command Example for One Type A PICC
To perform anticollision loop on up to two tags using the GUI:
1. Go to the ISO14443A tab.
2. Click Set Protocol.
3. Go to the Test tab.
4. Type the string E600 in String to Send window (see Figure 21).
5. Place up to two ISO/IEC14443A PICCs near enough to the TRF7970A EVM antenna to be read.
6. Click Send.
