Hi there!
I'm making my first proyect on the RFID-NFC's area, so im trying to build and make work an TRF7970A + MSP430f2370 (Also, i have another MCU to try both). I bought all the components that this requires (resistors, crystal, cond, oscillator, etc) and i want to make it work via SPI. Also, I built the 13,56 Mhz PCB Antenna ( As is shown on Texas Instruments Application Report SLOA135 ). the problem, is that i dont know how to make the main code that need to be implemented in MSP4302770 to make TRF7970A works well.
As i readed on TRF7970A's datasheets, i need to configure some registers to make it work as desired mode. BY THE MOMENT, I want to make it work as a card or an NFC target, just to read it with an TRF7970A EVM (I got it also). I readed the datasheet a couple times, but its dont clearly to me know what to do that because my english its not soo good,so i'm a little confused.
I would like if theres someone who had the kindness and courtesy to explain me slowly and patiently what i need to know and to do, to make TRF7970A work as NFC Target or Card mode with an MSP4302370 (and if someone got experience with another mcu, would be nice too).
Thanks you so much.
Armando.
