 Before we start this SD25 NFC workshop, we need to go over the needed evaluation boards and PC software. Three evaluation boards are needed for working with the examples. One would be the SD25R3911B Discovery Board. Two, SD25DV Discovery Board. And three, Cloud SD25TA Board. For interfacing software, either the SD25R3911B GUI PC software or NFC-enabled Android phone would install SD25 NFC app. You will need two micro USB cables, a one micro USB cable and one mini USB cable. The SD25R3911B board will need a micro USB cable to connect to your PC. For the SD25DV Discovery Board, you can connect either the micro USB or mini USB port to power up the board. However, if you need to update the firmware of the SCM32L phone onboard or debugging the firmware, you will need to connect via the mini USB cable. Before installing the SD25R3911B GUI software, internet connection will be needed for downloading supporting libraries. You can either install the software from the USB key that comes with the package or you can simply download the GUI software from st.com. During installation, notice that the program needs Microsoft Visual C++ 2015 Redistributable. Once you have successfully installed the software, connect the SD25R3911B board to your PC via micro USB cable and run the software. Click on Demo Board Check to see firmware version of the board. The current version is 1.1.12. If lower, you will need to update the firmware. You will need to install the SDM32 USB DFU driver if it's not already installed on your PC. Go to Subdirectory Driver. Choose the correct one for your version of Windows and install it. To update the Discovery Board firmware, first click on Firmware Update button under Help or you can also press Ctrl F. After that, choose the disco-stm32l4x6.hacks. After the firmware update process, you should start a clean power up the board. Once the GUI software loads, click on Demo Board Check to see the latest version of the firmware. Click on Calibrate Antenna and Adjust Regulators. And now you're ready to start the SD25 NFC workshop.
