#include <sdfat.h> in Arduino Programming

The sdfat.h library in Arduino is used for reading and writing files to an SD card. It is an extended version of the SD.h library and supports several additional features and functionality.

Usage of #include <sdfat.h>

To use the sdfat.h library in your Arduino program, include the following line at the beginning of your code:

#include <sdfat.h>

This library provides several functions to perform various operations on files stored on an SD card. Some of the commonly used functions are as follows:

SdFat SD

This object represents an SD card. You can use this object to access files on the SD card.

File myFile = SD.open(filename, mode)

This function is used to open a file on the SD card. You need to provide the filename and mode as parameters. The mode can be either FILE_READ or FILE_WRITE depending on whether you want to read or write to the file.

myFile.write(data)

This function is used to write data to an open file. You need to provide the data to be written as the parameter.

myFile.read()

This function is used to read a byte of data from an open file.

myFile.seek(position)

This function is used to move the file pointer to a specific position in the file. You need to provide the position as the parameter.

myFile.available()

This function is used to check whether there is data available to be read from an open file.

Conclusion

The sdfat.h library is a useful library for reading and writing files to an SD card in Arduino programming. It provides several functions to perform various operations on files stored on an SD card.
