Cf_Write_Sector

sub procedure Cf_Write_Byte(dim data_ as byte)

Description Writes a byte to Compact Flash sector buffer location currently pointed to by writing pointers. These 

pointers will be autoicremented upon reading. When sector buffer is full, its contents will be transfered 

to appropriate flash memory sector.

Parameters - 

data_

: byte to be written. 

Nothing.

The corresponding MCU ports must be appropriately initialized for CF card. See Cf_Init.

CF card must be initialized for writing operation. See Cf_Write_Init.

dim data_ as byte

...

data_ = 0xAA

Cf_Write_Byte(data_)

None.

sub procedure Cf_Read_Sector(dim sector_number as longword, dim byref buffer 

as byte[512])

Description Reads one sector (512 bytes). Read data is stored into buffer provided by the 

buffer

 parameter.

Parameters - 

sector_number

: sector to be read. 

- 

buffer

: data buffer of at least 512 bytes in length. 

Nothing.

The corresponding MCU ports must be appropriately initialized for CF card. See Cf_Init.

dim data_ as byte[512]

...

Cf_Read_Sector(22, data_)

None.

sub  procedure  Cf_Write_Sector(dim  sector_number  as  longword,  dim  byref 

buffer as byte[512])

Description Writes 512 bytes of data provided by the 

buffer

 parameter to one CF sector.

Parameters - 

sector_number

: sector to be written to. 

- 

buffer

: data buffer of 512 bytes in length. 

Nothing.

The corresponding MCU ports must be appropriately initialized for CF card. See Cf_Init.

dim data_ as byte[512]

...

Cf_Write_Sector(22, data_)

None.
