tcDspRomFs

Introduction

The tcDspRomFs class provides a mechanism to register a precompiled ROM filesystem with the TI DSP BIOS standard I/O libraries. Use of this routine will allow files to be accessed using standard fopen(), fread(), and fwrite() style function calls, as well as C++ stream operators.

Example

This is a simple example of tcDspRomFs usage:

 {
 {
     // read in external ROM filesystem class built from make_romfs tool
     // alternatively, one might reference a MityDSP application data sector
     // with preloaded filesystem data on it...
     extern tsDspRomFsNode MyFileSystem[];
       
     char buffer[128];

     tcDspRomFs* lpRomFs = new tcDspRomFs(MyFileSystem);
     lpRomFs->RegisterFileSystem("ROMFS");
    
     // read / parse data file...
     FILE* lpFile = fopen("ROMFS:data.txt","r");

     while(!feof(lpFile))
     {
        fread(lpBuff,1,128,lpFile);

        // Do something with the data...

     }

     fclose(lpFile);

     // typically, RomFs classes are not destroyed,  they occupy a minimum amount
     // of memory...

     ...
  }
