In the spi communication method, one chip succeeded in DEP communication through interlocking. But I do not know how to control two.Please, Where should I edit platform.h/rfal_nfc.c / st25r3916_comm.c?
Resolved! Handing the WTX frame correctly
Hello,I would like to verify if my approach to handling the WTX S-block over I2C is correct.Currently when I send "update binary" command with data field longer than 2 bytes I receive the S(WTX) frame in response, which is expected. The command is:x0...
Resolved! Problems communicating to the ST25R95 using SPI -- No communication from IC
My setup is as follows:ST25R95 is in a QFN32 chip holder (https://www.amazon.com/gp/product/B01N6NF3ME/), which allows me to test with test leads to a breadboard.Powering chip (VPS and VTx) with 3.3V with a bench power supply, which reads a constant ...
Resolved! Can I read ST25R3916 MAC address ?
I have two devices (which are with STM32F429 & ST25R 3916) from which I read NFC Wifi pairing and Bluetooth pairing tags. What can I change to make these two identical devices in terms of functionality (which are still physically different) indisting...
Resolved! ST25DV: why is a DC voltage delivered on VCC?
An internal voltage regulator allows the external voltage applied on VCC to supply the ST25DVxxKC, while preventing the internal power supply (rectified RF waveforms) to output a DC voltage on the VCC pin.Whats the purpose to output a DC voltage on V...
