Please Help me! How I can set registers below to active interrupt (IRQ) without send command via SPI?

After configured registers active IRQ when card is near, without send command.

Is possible?

Thank you.

WriteRawRC(ComIEnReg, 0xA0); //

Hi Marcos Riolo,

Actually the command is written into the CommandReg register, while interrupts enablement is controled by ComIEnReg and DivIEnReg registers, so it is possible to active IRQ without sending command via SPI.

Have a great day,

Please, give me example to set registrers: (Send IRQ without command SPI)

CommandReg

ComIEnReg

DivIEnReg

Are you success to send IRQ without command SPI when a new card come in the RF field?
