Gx3722SerialOutGetData

Purpose

Returns the specified serial-out channel 64-bit of data to be transmitted.

Syntax

Gx3722SerialOutGetData (nHandle, nChannel, pdwMostSigWord, pdwLeastSigWord, pnStatus)

Parameters

Name
Type
Comments
nHandle
SHORT
Handle to a GX3722 board.  
nChannel 
SHORT
Channel to get, channels are 0-2:
0.      GX3722_SERIAL_PAL_CH0: Channel 0.
1.      GX3722_SERIAL_PAL_CH1: Channel 1.
2.    GX3722_SERIAL_PAL_CH2: Channel 2.
pdwMostSigWord
PDWORD
Returns the specified serial-out channel most significant word that was set by Gx3722SerialOutSetData() API.
pdwLeastSigWord
PDWORD
Returns the specified serial-out channel least significant word that was set by Gx3722SerialOutSetData() API.
pnStatus
PSHORT
Returned status: 0 on success, negative number on failure.

Comments

The function set/returns apply the same time in microseconds for each serial transmitted bit for all 4 serial-out channels. The data bits pulse width for logic high pulse width and logic low pulse width cannot be longer than the bit rate, see the Gx3722SerialOutGetDataBitsPulseWidth() API  for more details.

Channels 0-2 can be programmed to operate as serial-out transmitter or as Static I/O, see Gx3722SerialOutSetMode() API for more details. When any of Channels 0-2 are set to Serial-out, all 4 channels direction is set to output.

Example

See the Gx3722SerialOutGetStatus () API for complete example.

The following example initializes and resets the GX3722 board:

 

SHORT nHandle, nStatus;

DWORD dwMostSigWord, dwLeastSigWord;

Gx3722SerialOutGetData (nHandle, GX3722_SERIAL_PAL_CH0, &dwMostSigWord, &dwLeastSigWord, &nStatus);
