FileCspReader Struct Reference

Detailed Description

Example code that shows you how to write a CspReader driver object.

The Web-Server uses the CspReader driver object when requesting data from the "dat" file generated by CspLink.

This example code uses the file system for reading the "dat" file. The constructor opens the "dat" file and method "diskRead" uses the Posix function fseek for setting the file pointer to the requested offset position and function fread for reading the actual data.
