DIO_DEVICE_CFG_isValid()

bool DIO_DEVICE_CFG_isValid

(

void

)

Checks header of non volatile runtime structure against discrete IO device profile header.

Called by DEVICE_PROFILE_INTF_cfgIsValid function of device profile interface. Function needs to be registered by DEVICE_PROFILE_register call.

Remarks

Function is called directly after non volatile memory read to check data consistency.

Returns

value as bool.

Return values

true	Header is corresponding to header of discrete IO device profile and non volatile data are valid.
false	Header is not corresponding to header of discrete IO device profile or non volatile data are corrupted.

Example

#include "device_profiles/discrete_io_device/discrete_io_device_cfg.h"
 
uint32_t DEVICE_PROFILE_register (DEVICE_PROFILE_INTF_Interface_t* pIntf)
{
    uint32_t error = DEVICE_PROFILE_INTF_ERR_General;
 
    if (NULL == pIntf)
    {
        error = DEVICE_PROFILE_INTF_ERR_PtrInvalid;
        goto laError;
    }
 
    ...
 
    pIntf->cfg.isValid = DIO_DEVICE_CFG_isValid;
 
    ...
 
    error = DEVICE_PROFILE_INTF_ERR_OK;
 
laError:
    return error;
}
