Dear Binshen] LIN,
yes those are the two registers that need to be changed, it is important that the smart card or tag you are interacting with, supports this speeds. I want to mention that this device is not recommended for new designs please check our CLRC663. if you have more questions let me know.
also a way to perform this using our library using the CLRC663 would be something like this:
status = phacDiscLoop_SetConfig(psDiscLoopParams, PHAC_DISCLOOP_CONFIG_TYPEA_I3P4_DRI, PHPAL_I14443P4A_DATARATE_848);CHECK_STATUS(status);status = phacDiscLoop_SetConfig(psDiscLoopParams, PHAC_DISCLOOP_CONFIG_TYPEA_I3P4_DSI, PHPAL_I14443P4A_DATARATE_848);CHECK_STATUS(status);
yeah,thanks for your answer! I will refer to your suggestion about clrc663.Also,I have another two questions to ask you ,please.firstly,Can you get a example for me to teach how to set Frame Waiting Tim(FWT) by using registers or other way?Secondly,where do I get the libary that you mentioned above?
Please check the library here Reader library, phhalHw_Wait(); is an API from the HAL ( Hardware abrasction layer) that wait for the milliseconds you need, but I would recommend that you check the library, download it you will find a folder called ApiDocumentation > NxpRdLib > html > NXP-NFCReaderLibrary-apiguide.html there is the explanation about the API available in the library.
if you have questions please let me know.
Have a great day !
OK,thanks very much,Jonathan! I will use the clrc663 when I make another new product,and I have a know for it. But now,I maintain the company's previous code of product that use mfrc632 .However ,I confused about some code in setting FWT,could you make a explanation for me ? I will paste the a little code screenshot below. How the values in the red box are calculated using FWI.I'm sorry to disturb you again.
Dear Binshen LIN,
Hope you are doing great, for this information please look in the NxPNfcRdLib > comps > phpall14443p3b or phpall14443p4 or phpall14443p4a > src > Sw> there ou can find a .h file for example phpall14443p4_Sw_Int.h there are the definitions of the FWT please check this path.
Dear Jonathan lglesias,
Thanks for answering these problems! I will study it .Also, I have another problem,do you use the stm32 ordinary IO port to simulate the ISO7816 protocol for contact card communicationu？
Have a great day!
we do not use such device, we have a list of contact readers that can help you to communicate in ISO 7816.
