How can i write incoming characters from uart into a sd card?

Hello Shivam,

You can for example use a Linked List

#include <ti/drivers/utils/List.h>

Driver Utilities -> List.h

You can refer to how it is used in the serial socket implementation:

Thanks for the link sir, further is it possible to edit the fatsd code to store the incoming characters from uart into sd card?
Where i need to change to write in the input.txt file. Is it okay to write in fwrite function and what changes i need to make in them ?

I am new to this programming environment.
How can i understand simple serial socket server example code given in the link sent by you?

I have tried to club uart echo and fatsd code but unable to get the desired result.
I am getting following warning:

Description Resource Path Location Type
#112-D statement is unreachable fatsd_nortos.c /fatsd_CC2652RB_LAUNCHXL_nortos_ccs line 141 C/C++ Problem

below is the statement

src = fopen(inputfile, "r");

Now no input file is being created, but earlier when i was using only fatsd code , file was created.

That could mean you have an if-else clause that will trap the code execution before you get to line 141.

Adding a while(1) before line 141 will result in the same warning.
