I made a PCB with ST25R3916. And now is coding for it. The only example I can find is X-CUBE-NFC6. Because my usage of ST25R3916 has some differences with the NFC061A. For example, I don't need AAT and only use a fixed external attena (is it possible...
I loaded the MB11414-A_v1.xml into ST25R3916 Discovery GUI. And find there is a register '0x68', but in ST25R3916's datasheet, I can't find 0x68, only 0x28. Where 0x68 comes from.If it's a typo, that is 0x68 is actually 0x28, write 0x00 to mask 0x20...
In 'X-CUBE-NFC6', I found the prefix code of NFCID2 in SENSF_RES is '0x02, 0xFE'. But the ISO 18092 says:The 6-byte number shall be randomly generated while the prefix code is ‘01’ ‘FE’. Other settings for the prefix code are RFU.So, what's the mean...
After trying to send any of these commands(90h, 91h, 92h) from ST25RU3993 it freezes and its carrier frequency disappears. If I try sending them using step debug, controller doesn't freeze, but I also can't know what did it send. Reg 38h = 0, so shou...
If it can, which pin on ST-Link/V2 should I connect to the last pin on Steval-Smartag1(which is said to be connected to USART2_TX)? Thank you!
I tried to programm STEVAL-SMARTAG1 with sample software provided on the webpage (https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/stm32-ode-function-pack-sw/fp-sns-smartag1.html) versi...
I'm doing something very similar, and using the steval-smartag1 as a jumping off point. I'd like to be able to use the UART as a second SPI device, but I'm concerned that doing that would interfere with the debug interface.On a related subject, can t...
Hi,I am using ST25DV04 discovery kit.I have used the GUI menu on the Kit to put the Tag in FTM mode to transfer picture.I am using another reader to read the picture.The flow I am following is as follows:Discover the NFC IC.Ask the IC for message len...
Hello!Dear ST technician!About 3993 ST25RU3993 Reader Suite software, inventory GB29768 tags, encountered a problem, want to consult:Now use STM32L476 +3933 chip, test the official source code (see the bottom picture), use ST25RU3993 Reader Suite,Inv...
Hi, I have a st25dv discovery kit for NFC application. I have downloaded stm32cubeIde and I opened the project example. I have this error when I build the project :ST25DV_DISCOVERY_FW_V1.1.2/Projects/ST25DV-Discovery/Demonstrations/ST25DVDemo/Src/fw_...
