How to setup parity on HSUART for PN742

ngassend — Tue, 24 Aug 2021 13:39:41 GMT

Hello,

We are developping a new reader based on PN7462 to replace our old system and we would like to be plug and play with the existing one !

Our problem is that we couldn't find how to select parity on UART serial interface

Our existing reader is configured with even parity and when we try to initialize communication with PN7462 we need to change the configuration of computer and select no parity !

If someone already changed the parity configuration of HSUART, thanks in advance to share how to do it !

Regards

Nicolas

Please refer to the demo of "PN7462AUPspPackageFull-v05_22_01\PN7462AU Software\LpcFw_phExHif". Please kindly refer to "6.3 PN7462AU_ex_phExHif" in UM10913 for more details. And the configure of PN7462 please refer to phExHif of NFC library.

Have a nice day.

Hi Fangfang,

it seem's that the code is for LPC1769 and not for PN7462

Could you tell us address of parity bit configuration in case of PN7462 ?

best regards

Hi Fangfang,

Do you have some news on the registry address to configure in PN7462 and not in LPC host !

This point is blocking for our project, and managment team thinking about to choose a different way without PN7462 chip !

Its really urgent if we want to save this project !

best regards
