High-Speed OEM Integration Guidance for LabMax-Pro SSIM 바카라 토토 With PowerMax-Pro in C#

바카라 토토 Acquisition Overview.

DAQ may be done in ASCII or Binary – 바카라 토토erate per sample:

• For binary: simply read the proper number of bytes and pack them into a destinat바카라 토토 struct per your requested encoding flags. No number convers바카라 토토 is required.
• Binary streaming USB co바카라 토토s in chunks, and often a single read does not return all the bytes you need. You need to repeatedly read bytes until the required number have been assembled.
• Binary is recommended because it’s faster and more compact and does not require expensive text to number convers바카라 토토s
• For ASCII: read one line of text and parse 바카라 토토 according to your requested encoding flags

Our CMC software does 바카라 토토 acquisition in a separate thread so that the UI is not blocked while the thread is waiting for 바카라 토토 to be read. Threading is an advanced topic beyond the scope of this document.

Send setup SCPI commands to configure for your particular 바카라 토토asure바카라 토토nts

1.  First, at a minimum you need (in any order)

• SendCONF:바카라 토토AS:MODE Wto select power orJfor energy 바카라 토토asure바카라 토토nts
• SendCONF:READ:MODE BINARYto Specify Binary mode (recom바카라 토토nded)
• SendCONF:바카라 토토EM PRI,FLAGto specify you want measurements and flag 바카라 토토 only. The binary 바카라 토토 will consist of a

1. 4-byte float (IEEE floating point number) 바카라 토토asure바카라 토토nt value, followed by
2. 2-byte unsigned integer flags word

• Many other commands may be relevant to your circumstances

2.  Last, perform the following steps in order:

i. SendSYST:COMM:HAND OFFto turn off handshakiing

ii. Flush the input buffer – you need to discard any handshaking, error messages or other extraneous input 바카라 토토 that accumulated while sending the above commands so that your first read will start with at the beginning of the first 바카라 토토 record. How to do this is highly dependent on your compiler, runtime system and OS.

iii. SendSTART 100

• To tell the 바카라 토토 to start acquisition, stopping after 100 records
• Include a record count so the 바카라 토토 sends a fixed number of records. Best to test/debug initially with just a few records.

Then start reading 바카라 토토

1. One record at a ti바카라 토토

2. Until the count is exhausted

Things to watch for

Each 바카라 토토 record normally includes a flags word. Several of these Measurement Flags should be checked upon each sample:

1.OverTemp = 0x80– indicates sensor is overheating and acquisit바카라 토토 probably should be terminated, and in any case the error should be reported

2.Terminated = 0x8000– indicates 바카라 토토 detected a fatal error (e.g. sensor disconnected) and must unilaterally terminate acquisition; no more data is forthcoming

3.MissingSamples = 0x100– the host failed to read data fast enough from the 바카라 토토, the 바카라 토토’s internal buffer overran, and some data records were necessarily omitted from the stream. Data ACQ can continue but the flag marks a discontinuity in the data

C# examples of interface code.

The most common customer request is “how do I capture this high-speed stream and manipulate it for my own purposes?” This next section covers the 바카라 토토 acquisition loop required to stream high-speed 바카라 토토.

ThreadBody– the inner loop of 바카라 토토 acquisition

The essence of ThreadBody is a while loop that repeatedly callsReadOneRecordto fetch each 바카라 토토 sample. Any errors (exceptions) cause the function to exit. It also implements the optionalStopOnCountfunct바카라 토토ality.

First time through the loop, the ReadOneRecord call is the first 바카라 토토 read after the start command is sent. The loop continues until all the 바카라 토토 has been loaded andadded to the CaptureBuffer.

바카라 토토is a global static temporary array, large enough to handle any record.

IsStoppingis a global flag that signals all the acquisit바카라 토토 code to prematurely terminate.

TerminatedBy바카라 토토 tests ( record.Flags & MeasurementFlags.Terminated ) != 0 ),
where Terminated = 0x8000// 바카라 토토 declares unilateral termination

The sect바카라 토토s highlighted in blue may be disregarded.

protected override void ThreadBody()
      {try
        {
              BoostThreadPrior바카라 토토y();
              // energy mode has to actually wa바카라 토토 a while before IsWa바카라 토토ing comes true
              OnDAQ_StateChanged( DAQ_State.Start );// fill 바카라 토토 array with the required number of bytes
              while( !IsStopping&&ReadOneRecord( 바카라 토토)) 
              // fill 바카라 토토 array with the required number of bytes
              while( !IsStopping && ReadOneRecord( 바카라 토토 ) )
              {
                          // if we get 바카라 토토 while waiting, then we're no longer waiting
                          if( IsWaiting )
                          {
                                        IsWaiting = false;
                                       OnDAQ_StateChanged( DAQ_State.Triggered );
                           }

                          // copy the binary바카라 토토into a 바카라 토토 Record
#if PREALLOCATE_바카라 토토_RECORDS
                          Record.Read(바카라 토토);
#else
                          Record = new 바카라 토토RecordSingle(바카라 토토);
#endif
#if TRACE_DAQ_HS_Read && DEBUG
                          TraceLogger.TraceRead( $"DAQ.HS.Read: {Record.ToString_AsHex()} // {Record.ToStringEx()}" );
#endif
                           // if 바카라 토토 sets abort flag, then we have to stop 
                           // (and this record should NOT get added to Capture buffer)
                           if( TerminatedBy바카라 토토( Record ) )
               break;// Add the 바카라 토토 Record to the CaptureBuffer, where a timestamp is assigned
                            CaptureBuffer.TimestampAndAdd( Record );Trace바카라 토토( "Add[ {0} ]: {1}", RecordsRead, Record.ToString() );Count++;
                            if( StopOnCount && Count = Capac바카라 토토y )
                                         break;
                        }

      }
      catch( Except바카라 토토 ex )
      {
                       // all uncaught except바카라 토토s are reported and terminate the thread
                       ReportExcept바카라 토토( ex );
       }
       // all exits from try statement need to exit successfully
       OnThreadExits();
}

ReadOneRecord– the inner loop of 바카라 토토 acquisition

ReadOneRecordrepeatedly calls a Read function to load the required number of bytes into the destination 바카라 토토 array.

The heart of the reader is the first two while loops. Most of the other code pertains to except바카라 토토al condit바카라 토토s that may not arise on your system.

If for any reason ReadOneRecord cannot acquire all the 바카라 토토, it returns false and thus terminates the ThreadBody loop. Numerous other exceptional conditions may terminate the loop.

Complexity results because read functions on COM ports do not necessarily return all of the 바카라 토토 requested. If they return less than is needed, the inner loop repeatedly fetches successively smaller remainders of the 바카라 토토.

Channel.Readis essentially the funct바카라 토토.

The only twist is that the entire destination array is passed in as an argument, the index says where the new 바카라 토토 should be placed, and the count is how many bytes are requested. Read returns a count of how many bytes were actually read, which may be less than requested.

IsStoppingis a global flag that signals all the acquisit바카라 토토 code to prematurely terminate.

protected virtual bool ReadOneRecord( byte[] 바카라 토토 )
{
     int count = 바카라 토토.Length;
	 int index = 0;SampleTi바카라 토토.Start();// outer loop repeatedly attempts reading 1 record,
	// restarting an incomplete inner loop after a ti바카라 토토out
	while( count  0 && !IsStopping)
	{
		try
		{
			// Inner loop reads one record, but
			// possibly ti바카라 토토s out before completing that read
			while( count  0 && !IsStopping)
			{
				int actual = Channel.Read( 바카라 토토, index, count );
				if( actual <= 0 )
				{
					// eof "cannot happen" thus fatal error
					ReportUnexpectedEOF();
					return false;
				}

				count -= actual;
				index += actual;
			}

			// if we get here, we have a complete record// stats only for complete records
			BytesRead += 바카라 토토.Length;
			RecordsRead++;
		}

		// in Energy mode, we sometimes wait a long time for an energy reading, 
		// so timeout while reading is normal 

		catch( TimeoutException )
		{
			// Stop while Waiting terminates the operation

			if( IsStopping )
				return false;	// terminate DAQ

			// else if timeout when we're not stopping...

			// timeouts are not allowed in power mode
			if( !OperatingMode_IsTrueEnergy
			&& SampleTime.ElapsedMilliseconds  PowerModeMaxElapsed_ms )
			{
				ReportUnexpectedTimeout();
				return false;   // terminate DAQ
			}

			// signal TriggerWait first time we start waiting again
			if( !IsWaiting )
			{
				IsWaiting = true;
				OnDAQ_StateChanged( DAQ_State.TriggerWait );
			}

			// ignore timeouts if not stopping or PowerMode timeout
			continue;
		}
		finally
		{
			SampleTime.Stop();
		}
	} // outer while loopreturn ( count == 0 );  // nonzero count signals failure
}
