Mmc_Fat_Read

mikroC - C Compiler for Microchip PIC microcontrollers

Prototype

void Mmc_Fat_Read(unsigned short *data);

Description Function reads the byte at which the file pointer points to and stores data into parameter data. The file pointer automatically increments with each call of Mmc_Fat_Read.

Requires File pointer must be initialized; see Mmc_Fat_Reset.

Example Mmc_Fat_Read(&mydata);

Mmc_Fat_Write

Prototype

void Mmc_Fat_Write(char *fdata, unsigned data_len);

 

 

Description

Function writes a chunk of data_len bytes (fdata) to the currently assigned file, at

 

the position of the file pointer.

 

 

Requires

File pointer must be initialized; see Mmc_Fat_Append or Mmc_Fat_Rewrite.

 

 

Example

Mmc_Fat_Write(txt, 21);

 

Mmc_Fat_Write("Hello\nworld", 1);

 

 

Mmc_Set_File_Date

Prototype

void

Mmc_Set_File_Date(unsigned year, char month, char day,

 

char

hours, char min, char sec);

 

 

Description

Writes system timestamp to a file. Use this routine before each writing to the file; other-

 

wise, file will be appended a random timestamp.

 

 

Requires

File pointer must be initialized; see Mmc_Fat_Append or Mmc_Fat_Rewrite.

 

 

Example

// April 1st 2005, 18:07:00

 

 

 

 

 

 

Mmc_Set_File_Date(2005, 4, 1, 18, 7, 0);
