Hello,
I have an application that needs to output a trigger signal at very specific position.
There is n triggers to be generated in this fashion :
Y axis ------>
|----------------|-----|-----|-----|-----| ... |-----|
0 1 2 3 4 5...n-1 n
0: Start Position
1...n : positions of triggers to be generated.
Physical distance between triggers is fixed and known.
Here's my current implementation
errCode = DAQmxCreateCOPulseChanTicks(m_3DTriggerTask,
TRIGGER_3D_COUNTER,
"",
ENCODER_Y_PIN_A,
DAQmx_Val_Low,
disToStartCnt,
highPulses,
lowPulses);
if (DAQmxFailed(errCode))
Log << err << CURRENT_FUNCTION << " Can't create 3D trigger output channel. Error " << errCode << endl;
errCode = DAQmxCfgImplicitTiming(m_3DTriggerTask, DAQmx_Val_FiniteSamps, nProfHw);
if (DAQmxFailed(errCode))
Log << err << CURRENT_FUNCTION << " Can't set continuous mode for clock. Error " << errCode << endl;
The issue arise when not moving, there is a lot of noise on the line ENCODER_Y_PIN_A since its a single phase of my encoder.
I'm wondering if someone knows an example code ( I have been looking but couldn't find) or could point me to a direction to fix this issue.
Thank you
