Cf_Detect

Cf_Enable

Cf_Disable

unsigned int Cf_Detect();

Description Checks for presence of CF card by reading the 

chip

 

detect

 pin.

Parameters None.
Returns

- 

1

 - if CF card was detected 

- 

0

 - otherwise 

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

Cf_Init

.

  asm nop;

while (!Cf_Detect());

PIC32 family MCU and CF card voltage levels are different. The user must ensure that MCU’s pin 

connected to CD line can read CF card Logical One correctly.

void Cf_Enable();

Description Enables the device. Routine needs to be called only if you have disabled the device by means of the 

Cf_Disable routine. These two routines in conjunction allow you to free/occupy data line when working 

with multiple devices.

Parameters None.
Returns

Nothing.

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

Cf_Enable();

None.

void Cf_Disable();

Description Routine disables the device and frees the data lines for other devices. To enable the device again, call 

Cf_Enable. These two routines in conjunction allow you to free/occupy data line when working with 

multiple devices.

Parameters None.
Returns

Nothing.

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

Cf_Disable();

None.
