Dear Sir,I am porting RFAL now. Based on 5.8 in UM2890, for HW chip selection, macro ST25R_COM_SINGLETXRX should be set. In st25r3916_com.c, the following code declared a local buffer. #if defined(ST25R_COM_SINGLETXRX) && !defined(RFAL_USE_I2C)stati...
The function we want is that it automatically recognizes when a small object with an NFC tag is mounted on a device.Thus, We want to have an NFC reader on our device and attach NFC tags to small objects to mount on the device.Is it possible to use ST...
I had powered VPS_TX of ST25R95 on 5V. So, ideally there should be improvement on the magnetic field as per the calculated data using that calculation tool. But I got adverse effect of it. It can't detect the tag, which works fine on 3.3V VPS_TX supp...
Hello,I've develop a solution that write and verify the content of nfc tag. I'm using the ST25R3911B-DISCO board to do this. The application is fast enought and work fine but, sometime it segfault. (~5/h). It always come after a read instruction (rea...
Hi guys,I'm new to this. I'm using STM32L476RG in combination with NFC 4 Click. I downloaded the X-CUBE-NFC6 but when i go to read an NFC Tag nothing happens. NFC 4 Click device has ben succesfully initialized. They are connected using I2C. What am I...
You're doing a great job.During the CR95HF reader test,The NTGA215 Tag is implemented as memory read/write. We proceeded by referring to the data sheet (61 page - ISO14443-A).Memory Read works normally, but the Memory Write function is not working pr...
Hello, we are developing related products using CR95HF reader.I am looking for NFC Card product with ST25TN01K-AFH5 chip for test purpose.I'm looking for a product in the form of an NFC card, not an IC chip.I'd appreciate it if you could recommend it...
Dear Sir,We are going to write a ST25R3916 driver (only support SO15693) for our platform which use ThreadX RTOS. As a porting reference, could you tell me where I can get the source code of ST25R3916 driver?best regardsDai Sai
Hi,We are using NFC reader IC: CR95HF using uart communication with our micro-controller.We are using external antenna for antenna, Is there any way to detect NFC antenna is connected to CR95HF ?Thank you in advance,Jignesh Patel
Hi,I am working on linux kernel v4.19 to bring up the cr95hf via SPI, there is a existing driver called st95hf, I enabled it, and it can be probed. can get ECHO back. when I used nfc neard to test the driver, it always gives errors like below:[ 501.0...
