ST25R3916-DISCO and STEVAL-25R3916B
reference graphical user interface
Introduction
The ST25R3916-DISCO GUI (STSW-ST25R010) software allows the user to configure,
evaluate, and communicate with the ST25R3916-DISCO and STEVAL-253916B kits using a
PC.
The software must be used with the ST25R3916-DISCO or the STEVAL-253916B kits,
which include a ready-to-use board to interface with the host PC through USB. This
software allows the user to evaluate the features of ST25R3916 and ST253916B, high
performance NFC universal device and EMVCo readers, communicating with the 32-bit
core STM32L476 MCU via the SPI bus.
The boards are powered through the USB port, and no external power supply is required.
They include an ST25R3916 or an ST25R3916B device, an etched antenna, and the
associated tuning components.
This software package includes the ST25PC-NFC software, which allows access to all
features of ST25 NFC / RFID Tags and ST25 Dynamic NFC Tags.

Page 13: Dpo
UM2517 Demonstration kits 1.4.4 DPO stands for dynamic power output. It is a software-based feature for the dynamic control of the transmitter driver resistance and the generated RF field, depending upon the presence of a PICC. A dynamic RF power adjustment can be useful in challenging environments where strong antenna detuning causes an abrupt increase in driver current and a violation of the maximum allowed field strength in the applicable standard. -

DPO panel enabled DPO measurement methods The two drop-down fields at the top of the DPO screen allow the user to configure the number of power levels and the source of measurement to be used to adjust the RF power. One of the two measurement methods (amplitude or phase) can be chosen. -

Page 16: Figure 12. Switching Resistance Values
Demonstration kits UM2517 Figure 12 shows an example of how the threshold levels can be set to switch between two resistance values. Figure 12. Switching resistance values In most cases, the user must reduce the generated field in close proximity of the reader. This means that sliders or threshold levels must be moved down into the region of interest. -
