Hi,
We are using TRF7970A NFC controller in our project and interface with STM32 controller via SPI. We used sample code downloaded from below link
http://www.ti.com/product/TRF7970A/toolssoftware
Using this we are able read write controller register but not able to read the card data when we place the card on RF antenna.(IRQ interrupt is not generating).
Is there any code modification required in above sample code to card read?
I found some reference firmware from below link which supports both Card Emulation Type A / B.
0456.ez430_TRF7970_UART_Card_Emulation_Type_A_or_B.zip
We want to know what is the difference between above sample and this card emulation firmware?
Is there any other sample code to read card data on polling method?
Regards,
Sanjeev
