Hi,

Sorry Henrik for making you confused. I am not sure that I can use SERIN with SHIFTIN/OUT so I mistakenly mixed them up.

Actually what Im doing is transmit a data at 13.56MHz by using TRH031M and the data is from pic16f877. Since trh031m has 4 type of modes, SPI,parallel etc, i configured my hardware to perform SPI mode. So Im trying to use "master slave" communication to send my data from PIC to trh031m as trh031m already pre-configured as a "slave" by default which u told me in the previous comment.

Can you kindly teach me what is the correct way to send my received data from PIC to trh031m? Do "master slave" communication work in performing my task?

appreciate your kind helps.

Regard.
