Prototype
sub function CF_Detect() as 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)
while (Cf_Detect() = 0)
nop
wend
Prototype
sub 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.
