Gx3722SerialOutSetNumOfDataBits

Purpose

Sets the specified serial-out channel number of bits to transmit.

Syntax

Gx3722SerialOutSetNumOfDataBits (nHandle, nChannel, nNumOfTxBits, pnStatus)

Parameters

Name
Type
Comments
nHandle
SHORT
Handle to a GX3722 board.  
nChannel
SHORT

Channel to set, 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.  
nNumOfTxBits
SHORT
Specified serial-out channel number of bits to transmit, number can be 1-64.
pnStatus
PSHORT
Returned status: 0 on success, negative number on failure.

Comments

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 sets serial-out channel 0 of bits to transmit:

 

SHORT nHandle, nStatus;

 

Gx3722SerialOutSetNumOfDataBits (nHandle, GX3722_SERIAL_PAL_CH0, 32, &nStatus);
