Function Documentation

int fwCcpc_GPIODisable	(	string	pCCPC,
		int	pLine
	)

This function disables a GPIO line as input or output line.

Parameters:

[in]	pCCPC	name of the CCPC to be reset.
[in]	pLine	number of GPIO line.

Returns:

= 0 no error found.

> 0 error found (related with CCPC Server).

= -1 error found (related with PVSS).

Example:

  (...)
  if (fwCcpc_GPIODisable("pclbcecs03",FWCCPC_GPIO_LINE_3) == 0)   // disables GPIO line no.3 
     (...)
  else
     DebugTN("Error found!");
  (...)

int fwCcpc_GPIOEnable	(	string	pCCPC,
		int	pLine,
		int	pDirection
	)

This function enables a GPIO line as input or output line.

Parameters:

[in]	pCCPC	name of the CCPC to be reset.
[in]	pLine	number of GPIO line.
[in]	pDirection	specifies direction of signal. ('0' means input and '1' means output)

Returns:

= 0 no error found.

> 0 error found (related with CCPC Server).

= -1 error found (related with PVSS).

Example:

  (...)
  if (fwCcpc_GPIOEnable("pclbcecs03",FWCCPC_GPIO_LINE_3,FWCCPC_GPIO_INPUT) == 0)   // enables GPIO line no.3 as an input line
     (...)
  else
     DebugTN("Error found!");
  (...)

int fwCcpc_GPIOGet	(	string	pCCPC,
		int	pLine,
		int &	pValue
	)

This function gets the level of a GPIO line

Parameters:

[in]	pCCPC	name of the CCPC to be reset.
[in]	pLine	number of GPIO line.
[out]	pValue	returns the level of the signal. ('0' means low and '1' means high)

Returns:

= 0 no error found.

> 0 error found (related with CCPC Server).

= -1 error found (related with PVSS).

Example:

  (...)
  if (fwCcpc_GPIOGet("pclbcecs03", FWCCPC_GPIO_LINE_3, SignalLevel) == 0)   // gets the signal level of GPIO line no3.
     DebugTN("GPIO line no.3 is set to " + SignalLevel);
  else
     DebugTN("Error found!");
  (...)

int fwCcpc_GPIOSet	(	string	pCCPC,
		int	pLine,
		int	pValue
	)

This function sets the level to a GPIO line

Parameters:

[in]	pCCPC	name of the CCPC to be reset.
[in]	pLine	number of GPIO line.
[in]	pValue	specifies the level of the signal. ('0' means low and '1' means high)

Returns:

= 0 no error found.

> 0 error found (related with CCPC Server).

= -1 error found (related with PVSS).

Example:

  (...)
  if (fwCcpc_GPIOSet("pclbcecs03",FWCCPC_GPIO_LINE_3,FWCCPC_GPIO_LOW) == 0)   // sets the signal level to low on GPIO line no3.
     (...)
  else
     DebugTN("Error found!");
  (...)
