Other Parts Discussed in Thread: DLP-7970ABP

Hi,

I am using DLP-7970ABP + MSP4302553 for reading data from NFC device. When i try to read i am just able to read the ID and the RSSI levels only. If i check status of my FIFO its showing '0' bytes present.

Someone pls help me in solving my problem.

Hi Ramesh,

This looks like a question for the NFC/RFID Forum. You may want to post it in that forum for a quicker response. Also, you will find many similar posts answered in that forum which may help you.

Hello Ramesh,

If you are using the code that Josh mentioned, you should be able to read ISO15693, ISO14443A and ISO14443B tags. If you have one of these tags and you are still not able to read it, make sure the IRQ_SEL jumper is configured for option 1 on the DLP-7970ABP.
