Functions
uint8_t *	PN_getPpmBuff (t_rtcPacket *pkt)
	Return a pointer to buffer indicated by NEXT This will be the next available free buffer(in the triple buffer scheme). Stack can now fill this buffer and once done call PN_relPpmBuff to indicate the PRU on new data. More...
uint8_t *	PN_relPpmBuff (PN_Handle pnHandle, t_rtcPacket *pkt)
	Swap NEXT with LAST and return new NEXT address . More...
int32_t	PN_checkLastPPM (PN_Handle pnHandle, t_rtcPacket *pkt)
	Update proc pointer in paket object and udpate descriptor if there is a new last buffer. More...
int32_t	PN_nextCpmRdy (PN_Handle pnHandle, t_rtcPacket *pkt)
	Swap CPM NEXT with LAST and set validLast flag. More...
uint8_t *	PN_getLastCpm (PN_Handle pnHandle, t_rtcPacket *pkt)
	Swap CPM LAST with PROC if validLast is true, clear validLast flag. More...
uint32_t	PN_enterFlushMode (PN_Handle pnHandle)
	Used to signal topology change to MRP state machine. More...
tLegStates	PN_getLegState (void)
	Returns the IRT Legacy mode state. More...
void	PN_setLegState (void *arg, void *arg2)
	Sets the state of legacy state machine This API is registered as a callback in PN_registerSetState. More...
void	PN_setLegPkt (void *arg, void *arg2)
	Sets the Ethernet packet to output during legacy startup Usually a copy of RTC3 PPM. This API is registered as a callback in PN_registerSetPkt. More...
int32_t	PN_initOs (PN_Handle pnHandle)
	Initialization function for all PN driver tasks, mutexes. More...
int32_t	PN_RTC_setupIsr (PN_Handle pnHandle)
	Interrupt management function Initializes PPM/CPM/DHT interrupts. (OS dependent!) More...
int32_t	PN_RTC_enableISR (PN_Handle pnHandle)
	Enables the PN interrupts. More...
int32_t	PN_RTC_disableISR (PN_Handle pnHandle)
	Disables the PN interrupts. More...
int32_t	PN_OS_txPacket (ICSS_EMAC_Handle icssEmacHandle, const uint8_t *srcAddress, int32_t portNumber, int32_t queuePriority, int32_t lengthOfPacket)
	Switch driver extension of TxPacket. More...

Function Documentation

PN_initOs()

int32_t PN_initOs

(

PN_Handle

pnHandle

)

Initialization function for all PN driver tasks, mutexes.

Parameters

pnHandle

Profinet Handle

Returns

None

PN_RTC_setupIsr()

int32_t PN_RTC_setupIsr

(

PN_Handle

pnHandle

)

Interrupt management function Initializes PPM/CPM/DHT interrupts. (OS dependent!)

PN_RTC_enableISR()

int32_t PN_RTC_enableISR

(

PN_Handle

pnHandle

)

Enables the PN interrupts.

Parameters

PN_OS_txPacket()

int32_t PN_OS_txPacket	(	ICSS_EMAC_Handle	icssEmacHandle,
		const uint8_t *	srcAddress,
		int32_t	portNumber,
		int32_t	queuePriority,
		int32_t	lengthOfPacket
	)

Switch driver extension of TxPacket.

This is using a critical section to protect re-entry of TX function. The protection scheme is borrowed from NDK and we use their code too. This requires to adhere to NDK priority scheme

Parameters

[in]	icssEmacHandle	ICSS Emac LLD handle
	srcAddress	pointer to TX packet
	portNumber	output port number
	queuePriority	output queue priority
	lengthOfPacket	TX packet length (without CRC)
