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. |
pnShiftMode |
PSHORT |
Returns the specified serial-out channel number shift out mode, shift out mode are: 0. GX3722_SERIAL_SHIFT_MODE_LEFT_MSB_FIRST: shifting data out left stating from the MSB. 1. GX3722_SERIAL_SHIFT_MODE_RIGHT_FIRST: shifting data out right stating from the LSB. |
pnStatus |
PSHORT |
Returned status: 0 on success, negative number on failure. |
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.
See the Gx3722SerialOutGetStatus () API for complete example.
The following example initializes and resets the GX3722 board:
SHORT nHandle, nStatus;
SHORT nShiftMode;
Gx3722SerialOutGetShiftMode (nHandle, GX3722_SERIAL_PAL_CH0, &nShiftMode, &nStatus);
