PN_API_IOD_activateIsoGpioObj()

uint32_t PN_API_IOD_activateIsoGpioObj	(	PN_API_IOD_Handle_t *const	pnHandle,
		const uint32_t	nsDelayTime,
		const uint32_t	nsDurationTime,
		const uint8_t	isomEvent
	)

Configures a comparator to generate a pulse on a chosen GPIO after/before a specified delay to
a new cycle. The service scans for an available object and sets it up.

Parameters

[in]	pnHandle	Profinet API Handle.
[in]	nsDelayTime	Delay value added to new cycle in nsec.
[in]	nsDurationTime	Pulse duration in nsec.
[in]	isomEvent	Isochronous ISR event ID (PN_API_IOD_TI_ISR_EVENT or PN_API_IOD_TO_ISR_EVENT).

Returns

result of the operation as uint32_t.

Return values

PN_API_OK	Success.
PN_API_NOT_OK	Something went wrong.
PN_API_ERR_PARAM	Invalid parameter.

Example

#include "pn_api_iod_isoch.h"
 
PN_API_IOD_Handle_t* pnHandle = NULL;
uint32_t status;
uint32_t to; //Usually obtained from the PLC
uint8_t isrEventID = PN_API_IOD_TO_ISR_EVENT;
 
pnHandle = PN_API_IOD_new();
 
status = PN_API_IOD_activateIsoGpioObj(pnHandle, to, 4000, isrEventID);
