Hi I am using ST25DV04KC tag in my product. During EN300330 test, there is a very high 2nd harmonic component radiated and exceeds the limit when the NFC reader is placed beside the tag. Anyone encounter this issue before?For Type-5 tag, is it normal...
Hi,I want to use ST25R3916B with nRF5340 from nordic semiconductor. The software for ST25R3916B is written mainly for STM32 MCUs. How can I port the software to nRF5340? How can I start at all? Thanks.https://www.st.com/en/embedded-software/x-cube-nf...
in NFC readers product selection page the "interface to host" feature for solutions ST25R3916, ST25R3916B, ST25R3917B, and ST25R3919B is listed as "SPI" only, But when I open the product page of these solutions I find that they support both SPI and I...
Hi everyone,I am using a ST25DV04KC-IE8T3 connected to a low power consumption display.I'm trying to power the display with ST25 when ST25 detect the RF. (the display can work from 1.5V to 5V with just on/off configuration).ST25DV04KC-IE8T3 GPO is op...
I have a question regarding ST25R3911B resource optimization.https://www.st.com/resource/en/user_manual/um2890-rfnfc-abstraction-layer-rfal-stmicroelectronics.pdfAdditionally, I have read the RFAL user manual mentioned below, and in the FEATURES CONF...
Hi! I am attempting to use the current 1.10.0 Java SDK on a windows 10 pro computer with JDK 1.8.0_144. (Java 8) x86 - for use with ST25R3911-DISCO at first, and hopefully then the Feig USB reader. I have carefully followed the st25pcdemoapp_...pdf d...
Hi all, I have designed and built a custom circuit using the ST25R3916 (in differential mode with AAT) and a ATxmega128A4U micro controller. I have spent the last two weeks trying to get it working so my phone can detect it as a card as a starting p...
Hello,I'm building a proprietary NFC reader based on ST25R3917 chip and STM32F070CBT6 MCU. I use Bare Metal approach without any HAL or RFAL which might complicate my query a bit but I'll try to ask anyway. So far I'm able to Poll Type A and Type B c...
Hello,I am working on a version of the STM32L476RG_NUCLEO_AP2P_PROP_NFC8 demo included with the RFAL library examples, trying to get it going on a NUCLEO-F072RB.I have my code running, and if I bring an L476RG flashed with the unmodified AP2P demo, t...
Hello,This is sort of related to my earlier post, and is an effort to uncomplicate things a little. I have configured a project using X-CUBE-NFC6 on a NUCLEO-L476 and NFC08A1 board. The demo runs fine, and can detect the different technologies.Howe...
