Does this library support A1 Antenna antenna card reading? #20

How should I implement this part of the logic?

image This is the antenna I use. I have been unable to read the card after I put the card in the sensing area of the antenna. The following is the serial port printing data： No RX, irq1: 61 irq0: 28 Could not determine UID, perhaps some cards don't play well with the other cards? Or too many collisions? loop.. CLRC663 fifo_length: 0 cmd_transceive rx_len: 0 Sending REQA No RX, irq1: 61 irq0: 28 Could not determine UID, perhaps some cards don't play well with the other cards? Or too many collisions? loop..

So much can go wrong... First step: is the antenna and RF part working? If you have a scope, twist some wire around a pencil to form a coil, and attach it to the scope probe and see if the antenna is producing a field.
