Hi guys,
I port NXP reader library v4.050.03.011702 for my custom board using CLRC663 and other MCU, it work except LPCD and I have no idea how to make LPCD work.
And I try to use the same port for newer library v4.060 (NxpNfcRdLib_RC663_LPC1769_v04.06.00_Full_SW2978) to give it a shot, but it's not work, even the normal operation. When it runs the FW said "tech detected" but there was no card near the reader. Don't know the reason.
Any suggestion? Thanks very much.
Hello Kevin,
About LPCD mode of CLRC663, you should not focus on NFC reader library, In CLRC663 datasheet & AN11145, LPCD has been describe it clearly, you should set following registers:
(1) Register for standby
(2) Register for LPCD
(3) Interrupt register
AN11145: http://www.nxp.com/documents/application_note/AN11145.pdf
Datasheet: http://www.nxp.com/documents/data_sheet/CLRC663.pdf
See Following please:
Have a great day,
Weidong
