[Reqest Doc] wiring #1

Could you update README or make a new file with wiring between Pi PICO and module TRF7970A?

gentilkiwi commented 2 days ago

The README is work-in-progress. All kameleon boards (including piko) are here: https://oshwlab.com/gentilkiwi/st25tb_kameleon

are you thinking of developing a flipper zero board? Flipper zero allow communication with spi on exported GPIO and has some pins for EN and IRQ.

gentilkiwi commented 1 day ago

:) No, the Flipper Zero and Proxmark3 are already best for all use cases (and the TRF7970A is very limited)

Yes is very limited, I hate this chip, but is the best solution which we have for 14b emulation. For years I have looked for an alternative but there has never been one. I wasted many hours trying to emulate a 14b tag without ever being successful, I had learned the datasheet by heart, the registers and the default values. When I found your project I didn't want it to be possible, I was convinced that TRF7970A was not capable of emulating a 14b tag.
