PN_API_IOD_isoInterruptEventCbf

typedef uint32_t(* PN_API_IOD_isoInterruptEventCbf) (PN_API_IOD_Handle_t *const pnHandle, const uint8_t isomEvent)

Callback function prototype to handle the event triggered by isochronous interrupt (typically Ti/To).

The user application is required to implement this function to handle the interrupt triggered by Ti/To events activated using PN_API_IOD_activateIsoIsrObj().

Parameters

[in]	pnHandle	Profinet API Handle.
[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_callbacks.h"
#include "pn_api_iod_isoch.h"
#include "pn_api_iod_startup.h"
 
//Implement the callback function in the user application
uint32_t PN_APP_IOD_cbIsoInterruptEvent(PN_API_IOD_Handle_t *const pnHandle, 
const uint8_t isomEvent)
{...}
 
PN_API_IOD_Handle_t* pnHandle = NULL;
uint32_t status;
 
pnHandle = PN_API_IOD_new();
 
//Store callback functions implemented by the user application
PN_API_IOD_Callbacks_t callbacks = {
    .isoInterruptEvent = PN_APP_IOD_cbIsoInterruptEvent,
    ...}
 
//Register callback function
status = PN_API_IOD_registerCallbacks(pnHandle, &callbacks);
