Before connecting, we’ll discuss some of the features of this StampPlot interface, shown
in Figure 8-8. The uppermost plot shows the values read from the photoresistor, plotted
with a blue line. The plot below shows the output drive, plotted in black.
The photoresistor plot has these characteristics:
DEBUG "!FCIR (PTIME),(AINVAL1),0.3A,(Blue)",CR,
DEBUG "^AWTH 2",CR,
√

•
Run StampPlot macro sic_pc_pid_eval.spm.
The default range is 0 to 2000.
The Setpoint is plotted in red.
