Gx5733ModuleGetHandshakeOutputMode

Applies To

GX5701, GX5702, GX5704

Purpose

Returns the Module’s Handshake output mode.

Syntax

Gx5733ModuleGetHandshakeOutputMode (nHandle, nPort, , pnMode, pnStatus)

Parameters

Name
Type
Description
nHandle
SHORT
Handle to a GX5733 board.
nPort
SHORT
Module port 0 (GX5733_PORT0) only.
pnMode
PSHORT
Handshake output mode:
0. GX5733_MODULE_HANDSHAKE_OUTPUT_DISABLE: Handshake output mode disabled.
1. GX5733_MODULE_HANDSHAKE_OUTPUT_ENABLE: Handshake output mode enabled.
pnStatus
PSHORT
Returned status: 0 on success, negative number on failure.

Comments

The GX5733 can have one Module installed. The installed module can use either Direct Output/Input or Strobed Output/Input with handshaking.

When using Direct Output/Input on each strobe signal transition, the user is responsible for setting polarity via Gx5733ModuleSetExtStrobeEnablePolarity.When using Strobed Output/Input with handshaking the hardware controls the Output/Input sequences. The handshaking mechanism is implemented using input and output control and strobe signals. See Module Strobed Output Input Handshaking section for typical handshaking events in order to output a single double word of data.

Example

The following example returns modules port 0 Handshake Output mode:

 

SHORT nMode nStatus;

Gx5733ModuleGetHandshakeOutputMode (nHandle, GX5733_PORT0, &nMode, &nStatus);
