Gx3756SerialOutGetMode

Purpose

Returns the specified serial-out channel operation mode.

Syntax

Gx3756SerialOutGetMode (nHandle, nChannel, pnMode, pnStatus)

Parameters

Name
Type
Comments
nHandle
SHORT
Handle to a GX3756 board.
nChannel
SHORT
Channel to get, channels are 0-3 board based (channels 0-3 in group 0):
0.      GX3756_SERIAL_CH0: Channel 0.
1.      GX3756_SERIAL_CH1: Channel 1.
2.      GX3756_SERIAL_CH2: Channel 2.
3.    GX3756_SERIAL_CH3: Channel 3.
pnMode
PSHORT
Returns the specified serial-out channel operation mode, operation mode can be:
0.      GX3756_SERIAL_MODE_PORT_IO: The channel is set to a static I/O.
1.    GX3756_SERIAL_MODE_TRANSMIT_DATA: The channel is set to a serial-out transmitting data.
pnStatus
PSHORT
Returned status: 0 on success, negative number on failure.

Comments

When any channel is set to GX3756_SERIAL_MODE_TRANSMIT_DATA mode, all four channels are set to output.

Channels 0-3 (Group 0) can be programmed to operate as serial-out transmitter or as static I/O, see Gx3756SerialOutSetMode() API for more details. When any of Channels 0-3 (Group 0) are set to Serial Out, all 4 channels direction is set to output.

Channels 3-7 (Group 1) can be programmed as an external trigger source to channels 0-3 (Group 0), when they are set to serial-out operation mode. See Gx3756SerialOutSetMode(), and Gx3756SerialOutGetTriggerSource() APIs for more details.

See the Gx3756SerialOutGetStatus () API for complete example.

Example

The following example returns serial-out channel 0 operation mode:

 

SHORT nHandle, nStatus;

SHORT nMode;

 

Gx3756SerialOutGetMode (nHandle, GX3756_SERIAL_CH0, &nMode, &nStatus);
