Instead of launching the oscilloscope with the {{key press|o}} key and clicking buttons and knobs, it is possible to instantiate the instrument from a Nasal script.<br /> | |||
Open the Nasal Console (or the REPL interpreter if you prefer) and execute these lines: | |||
<syntaxhighlight lang="nasal">var Osc = oscilloscope.show.new(); | |||
var myFunc = func {return 10+4*math.sin(D2R*int(100*systime()));}; | |||
Osc.setTimeBase(0.2); | |||
Osc.setChannelInput(2,'/controls/engines/engine/magnetos'); | |||
Osc.setChannelInput(1, myFunc); | |||
Osc.setGain(channel:1, gain:2); | |||
Osc.setGain(channel:2, gain:2); | |||
</syntaxhighlight> | |||
Please note that buttons and knobs are still reacting to manual clickings.<br /> | |||
You can explore other nasal instructions like: | |||
<syntaxhighlight lang="nasal"> | |||
Osc.setChannelInput(2, func {return 5.5;}); | |||
Osc.setChannelInput(1, 'var alt = getprop("/position/altitude-ft"); return alt/10;'); | |||
</syntaxhighlight> | |||
