nHandle |
SHORT |
Handle to a GX3756 board. |
nChannel |
SHORT |
Channel to set, 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. |
pnStatus |
PSHORT |
Returned status: 0 on success, negative number on failure. |
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.
The following example issues a software trigger to serial-out channel number 0:
SHORT nHandle, nStatus;
Gx3756SerialOutTrig (nHandle, GX3756_SERIAL_CH0, &nStatus);
Gx3756SerialOutReset, Gx3756SerialOutSetArmState, Gx3756SerialOutSetBitRate, Gx3756SerialOutSetData, Gx3756SerialOutSetDataBitsPulseWidth, Gx3756SerialOutSetTriggerSource, Gx3756SerialOutSetMode,
Gx3756SerialOutSetNumOfDataBits, Gx3756SerialOutSetShiftMode, Gx3756SerialOutSetTriggerDelay, Gx3756SerialOutSetTriggerSource, Gx3756SerialOutTrig, GxFpgaGetErrorString
