3.5.3 EApiGPIOSetLevel

This function writes the GPIO pins to change the status. The pins can be low or high.

Syntax:

EApiStatus_t EAPI_CALLTYPE EApiGPIOSetLevel (

__IN uint32_t ID,

__IN uint32_t Bitmask,

__IN uint32_t Level

);

Parameters

ID: Id of GPIO index

Bitmask: Unused, fill in 0

Level: Set GPIO status GPIO_LOW or GPIO_HIGH

Return value

Status codes (EApiStatus_t)

Example (C#)

private static UInt32 EapiStatus;

EapiStatus = EApiGPIOSetLevel((uint)GPONumber, 0, GPIO_HIGH); //Set High

if (EapiStatus !=EAPI_STATUS_SUCCESS)

return;

3.6 VL3 BPC DIO only functions

These functions set the VL3 BPC DIO pin state. EApiHWMGetCaps must be called before

calling this function. EApiHWMGetCaps returns the number of DIO pins which can be set.

3.6.1 EApiBoardGetValueWithIndex

Function: To read board information values with index.

Syntax:

EApiStatus_t EAPI_CALLTYPE EApiBoardSetValueWithIndex (

__IN EApiId_t Id,

__IN uint32_t Index,

_OUT uint32_t *pValue

);

Parameters

Id: ID of value information

Index: Index of information

pValue: Value of information

Return value

– Status codes (EApiStatus_t)

Example (C#):

private static UInt32 EapiStatus;

UInt32 u32Status = 0;

UInt32 u32Index = (UInt32)DIO_index;

// Get DIO type

EapiStatus = EApiBoardGetValueWithIndex(EAPI_ID_BOARD_SENSOR_DIO_DIREC-

TION_INTERNAL, u32Index, ref u32Status);

if (EapiStatus == EAPI_STATUS_SUCCESS)

type = (u32Status == 1) ? true : false;

else

return false;
