Hi all,

I am working with LPC2468 board from embeddedartists using the IAR Embedded Workbench 7.3

I want to write my results read from a double variable into a txt file created on the PC. I read on the forums and already set the library settings to FULL to read the Dlib_Config files.

           #include nxp/iolpc2468.h
           #include stdio.h
           #include string.h
      
           FILE* file;
           file = fopen("H:\\test.txt","rw+");
           fprintf(file,"%A\n",max_temperature_DegC);
           fclose(file);

I used this standard code. Although I have no compiler warning/errors. But when I debug; the code it gets stuck in the undefined handler (abort handler) as I can see it in the disassembly. The output file is not created and has no output. I am not using UART or any I2C to write to the file.

Is it possible to write to a file on a PC directly or one has to use UART/I2C ??

Thanks
