Hello!We have combined the CR95HF receiving antenna and wireless charging capability on 13.56Mhz. We monitor placed device by user on wireless charging and in this mode we disable attempts to read RFID.When if wireless charge is enable, on ST_R0 is 1...
Hello!
On my board STM32F401 communicates with CR95HF via SPI use X-CUBE-NFC3.
After powering up, initializing the STM32F401 for 2MHZ SPI, run the st25r95Initialize() function.
I've noticed that CR95HF is unresponsive unless the power from a pr...
Good afternoon!Please rate my first experience in analog circuitry.The following task was released: to develop low cost a DC overload protection circuit (cut-off consumption more than 1.8A).Explanations for the scheme:A low-pass filter was made on th...
Thanks for the answer.I noticed this behavior on my custom board.I don't have X-NUCLEO-NFC03A1 expansion board.To test the behavior, I decided to reproduce his on STM32F401 Nucleo-64 connected to CR95HF by wires on my board similar to connection X-NU...
