For now, the a scope will not be made full because I have not figured out Notes for controls the user can play with
how to implement the bearing control. Just put the display up on the screen.
The main ppi scope will take up the right hand side of the screen. You need to leave about Here are the controls that I am proposing
a 1/2 inch margin around the sides of the circular scope.
1. Intensity
2. Focus
3. Astignatism
4. Range selection (for both a scope and ppi scope)
5. Sensitivity
6. Clutter elimination (I believe only ppi scope; please research)
7. There is some sort of control having to do with the mangatron
but I don't know what its called and what it does.
8. Bearing (only for a scope) which in the old days uses a servo motor to
rotate the antenna. I don't know what form of feedback (text on the
screen or mechanical numbers on a dial)
(Please suggest other controls I may have missed.)
Now, for controls, the tentative approach is to use encoders (that do not
have end stops so they cannot be broken by visitors at the museum) I will
need help on how to impliment them. I am guessing a few raspberry pies to
handle the encoders. I am thinking of encoders have one common terminal and
a clockwise pulse terminal and a counter clockwise pulse terminal.
Let do this like this. The control handling will be a different class and run
as a separate thread from the display. Each control function will have a parameter
for how many pulses received and in what direction. That would be permanent.
Temporary code necessary for changing control selection and value via the
keyboard until I get the necessary hardware for the controls.
