I use ST25DV to write binary files. I can only write one BLOCK at a time. I think every time I write is Multiple BLLOCK,Each BLOCK has 4 bytes. If I want to write 64 bytes(binary fules）, the boad have to read and write 16 times. If I want to read and...
There is a Spiral antenna in the X-NUCLEO-NFC04A1. The link is https://www.st.com/content/st_com/en/products/ecosystems/stm32-open-development-environment/stm32-nucleo-expansion-boards/stm32-ode-connect-hw/x-nucleo-nfc04a1.htmlBy the document AN2972(...
my reader is st25r3911b-discover,the tag is st25dv04k,when I write file(the bin file )to tag,the reader wrote a block (four byte)to tag every time ,how to designer reader for writing more block to tag every time.for example two block or more.than...

Hi HC，Thank you for your professional reply.!Today I modify antenna parameter. As follow Figs, It shows how to test ro and ri value. Is it right?By this way, ro = 18.9 mm, ri = 11.3 mm, N =10, ==> L = 4.4uH.As followBy those spiral parameter, the PC...
thank you again;According to your formula above,I designer a single layer antenna in PCB, Please help me check what is wrong？a = 14mm; N = 11; c = 8.6mm; u0; ri = 9.7mm; ro = 18.3mm.Conductor: width = 0.6mm; spacing = 0.2mm; thickness = 35um.:...

Thank you for your reply,Your method is right,but I want to design a double layer antenna（in PCB）.In the file your double layer antenna is coming soon, I don't know how it is going.I hope that you can give some design methods.What should ...
I want sak more a question,when I write file(the bin file ),the reader wrote a block (four byte)to tag every time ,how to designer reader for writing more block to tag every time.for example two block or more.
