I ma using Nucleo-L467RG connecting to CLEV6630B board. I can get ATQA easily using this code, however I can not get the UID. I know I have to send 0x93 and 0x20 to FIFO buffet and then read it but it does not work!
while(1)
{
CLRC663_write_reg(0x00,0x00);
CLRC663_write_reg(0x02,0xB0);
uint8_t data[2] = {0x00, 0x00};
CLRC663_write_fifo(data, 2);
CLRC663_write_reg(0x00, 0x0D);
CLRC663_write_reg(0x02,0xB0);
CLRC663_write_reg(0x28,0x8E);
CLRC663_write_reg(0x06,0x7F);
CLRC663_write_reg(0x07,0x7F);
CLRC663_write_reg(0x2C, 0x18);
CLRC663_write_reg(0x2D, 0x18);
CLRC663_write_reg(0x2E, 0x0F);
CLRC663_write_reg(0x05,0x26);
HAL_Delay(10);
CLRC663_write_reg(0x00,0x07);
HAL_Delay(10);
uint8_t Read_Buffer[]={0};
CLRC663_read_fifo(Read_Buffer, 2); // Read FIFOBuffer - Read FIFOBuffer (While sending this byte on MOSI line, the RC663
uint8_t* ATQA0= Read_Buffer[0]; //answers with the first byte of the FIFOBuffer)
uint8_t* ATQA1= Read_Buffer[1]; //random byte to read second byte of the FIFOBuffer (While sending this byte
ATQA = (Read_Buffer[1] << 8) | Read_Buffer[0]; // Here we got the ATQA
}
Could anyone help me on this, please? where am I going wrong? I could not find a good AN that explain well what to do, they are all vague. AN12657 just takes you up to getting the ATQA and there is no guide for the UID.
CLRC663_write_fifo(0x93,1);
CLRC663_write_fifo(0x20,1);
Really appreciate any ideas.
