Add NFC tag library to Segger Embedded Studio Project

[Ricards]

Hello! I don't quite understand how to properly link NFC tag library (nfc_t2t_lib_gcc.a) to Segger Embedded Studio Project.

Steps I did:

1. Add nfc_t2t_lib_gcc.a to the project with: Add Existing File -> and select particular file

2. Added directories where to search for include files: Edit Options -> Preprocessor -> User Include

$(NrfSdkPath)/components/nfc/t2t_lib

$(NrfSdkPath)/components/nfc/t2t_lib/hal_t2t

3. also added hal_nfc_t2t.c file to the project

But when I build I get following error: In function nfc_t2t_emulation_start': 1> C:\build\HUSS-NFCL33-JOB1\private\nfc_t2t_lib\armgcc/../nfc_t2t_lib.c:566: undefined reference tohal_nfc_start'

I am running Embedded Studio on Ubuntu 16.04 and using SDK version 14.1.0.

Hoping for help!

Managed to solve the issue. It turns out, that I was missing NFC configuration in sdk_config.h file. I added following lines in sdk_config.h and it solved the issue:

#ifndef NFC_T2T_HAL_ENABLED
#define NFC_T2T_HAL_ENABLED 1
#endif

#ifndef NFCT_CONFIG_IRQ_PRIORITY
#define NFCT_CONFIG_IRQ_PRIORITY 7
#endif
