 Merci d'avoir regardé, je m'appelle Vincent Latour et je suis l'engineur d'application software à ST Microelectronics. Je voudrais vous montrer dans cette vidéo comment un développeur comme vous peut utiliser le R3911B Reader ST25 avec notre software ST25 PC pour démonstrer les taxes dynamiques de la dynamique de la dynamique de la dynamique de la dynamique de la dynamique de la dynamique. Mais d'abord, let's introduce the two stars of the video. The ST25DV Discovery is a demonstration kit to evaluate the features and capabilities of the ST25DV series. The kit is divided in two parts. The first one is the motherboard. And the other one is the motherboard based on the ST25DV 04K dynamic tags, which is ISO 15693 and NFC forum type 5 compliant. So now, let's have a more detailed look at the motherboard. The ST25DV in DFN12 package, the antenna and the motherboard connector. This board is a ready to use kit featuring ST25R certain 11B product, an highly integrated HF Reader NFC initiator IC. This Reader is one of the most powerful the market with 1.4W output power. It supports all NFC and HF standards. It embeds the unique automatic antenna tuning, dynamic power output and low power output mode. Those kits can be ordered online at the address shown on the screen. Finally, you will need to download and install the ST25PC01 software from the ST website. This software is a Java application running on Windows PCs. It has been developed to demonstrate RF communication with all NFC tags from ST. This software supports multiple Fag Readers and the ST25R 3911B Reader. Let's start with our demonstration with ST25DV anti-collision procedure. In this demo, we use the ST25R 3911B Reader to detect multiple ST25DV tags. This shows the benefit of the ST25DV being a long range tag. It also demonstrates the reading distance of the Reader. Et pour votre information, le hâte de la stade de displays est à plus de 10 cm. Reste le PC software Java et ouvrez l'amélioration. Comme vous pouvez le voir, type 5 anti-collision est sélectionnée par défaut. Puis cliquez sur continue scan bouton. Les 3 ST25DVs sont détectées et leur UID est display. Let's continue with the firmware upgrade demo, based on the fast transfer mode feature. This feature is using the 256 byte buffers of fast memory embedded in the ST25DV product. This demo shows that the reader is able to upgrade the firmware of several boards simultaneously. Please note that in this case, we are using class 1 antenna. Let's check the current firmware version of the motherboard. It's 1.0.6. Then enter the fast transfer mode demo by selecting FTM icon. To upgrade the firmware of the motherboard, select the firmware upgrade menu. Then select the firmware file to transmit. The file size is about 110 kb. Activate fast mode feature to enable faster response from ST25DV. And finally, click on send to RF. The PC software first sends the password required by the MCUs, and then the transfer starts. All ST25DV discovery boards are updated simultaneously. After 42 seconds, the firmware has been successfully upgraded on all boards. As you can see, the firmware version is now 2.0.0. The firmware uploads through NFC simultaneously on multiple boards can bring great benefits to the industrial sector as for machine maintenance or parameter settings. To continue our demo, we'll show that the FTM feature can also be used to upload data from the MCU to the reader. On the ST25DV discovery board, enter the FTM menu, then click on the picture icon. The selected picture size is about 16 kb. In the PC software, click on the picture transfer demo. Select download the picture from the tag. Activate fast mode feature. Then click on start transfer. After 6 seconds, the picture has been successfully transferred and is displayed in the PC software. The PC software opens the tags menu, then ST25DV and select specific commands. Select the send interrupt by JPO command and click on send RF command. ST25DV supports a dedicated RF command to generate JPO interrupt to the MCU. As you can see on the LCD display, MCU is detecting the interrupts from ST25DV. Merci d'avoir regardé. Nous espérons que vous avez aimé cette vidéo. N'hésitez pas à abonner à la chaîne ST25DV et d'offrir des features intéressantes pour votre application NFC. À bientôt.
