1. change MATLAB work path to optiCommLabProc

2. run setisimenv.m to add simulation path, and runMainOfflinePPG.m will be opened automatically

3. open offline/loadOfflineDataPPG.m for setting offline parameters:

   1. the main parameters allow to change:

      % controller
      isCaptureDSO           = 0; % set to 0 for loading data from local driver
      isPltCapturedData      = 1; % plot time domain waveform
      isSaveData             = 0; % is save MATLAB workspace data to driver
      dataLen                = [];  % {number or []}, always let it be []
      

4. open config/cfgOfflinePPG.m for DSP parameters configuration

   1. PPG with PRBS23 testing Okay, please choose "prbs23_18" for priority test
   2. Match the baud rate "fBaud" to PPG settings
   3. Some other DSP parameters could be changed in this script
