ST25R200 read/write examples

[Atomic1]

Hello,

I am using the ST-25R200 ready-to-use NFC evaluation board for my application. I have already used the ST25R200 EVAL GUI software which functions without any problem. 

Since I want to develop my own software and integrate it for the application which requires to read/write to the NFC tags, I went through the forum and found out some much helpful ST25NFC_Embedded_Lib_ST25R200_1.8.0. After installing, I went through the example ndef_read.c and ndef_write.c codes (which are very thorough in and of themselves).

I am trying to use these codes along with the required drivers and header files using VS code. I have properly included the paths for all the required headers. However, while compiling I am getting the error: reent.h source file (dependency of rfal_nfc.h) could not be opened. I am also unable to find the said header file in the installed embedded library folder.

Request for any help, since I am a novice in programming microcontrollers

Hi,

reent.h is not directly included by RFAL code. It sounds more like a clib issue. Maybe this one helps:
