Prototype
function CF_Detect() : byte ;
Returns
-
1
- if CF card was detected
-
0
- otherwise
Description
Checks for presence of CF card by reading the
chip detect
pin.
Requires
The corresponding MCU ports must be appropriately initialized for CF card. See
Cf_Init.
Cf_Init.
Example
// Wait until CF card is inserted:
while (Cf_Detect() = 0) do
while (Cf_Detect() = 0) do
nop;
Prototype
procedure Cf_Enable();
Returns
Nothing.
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.

Nothing.
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.
