Interface and Application programming

This weeks assignment was to write an application that interfaces with an input &/or output device. I had some input devices I made two weeks ago in the input week so I connected them to my computer and ran the python file in a text editor.

hello.txrx

I began with the txrx input and changed the obvious codes like the colors, font and window size.

Here is the window size bigger than the original

To make any color I want I found this great Hex color generator. On the bottom of the screen you get the Hex code for the color you made in the generator.

Here is the program with a new color

Next thin I did was that I change the WINDOW size which was on the top of the page. Now I noticed was that the rectangles changed as the size of the window changed. When I looked at the codes for rect1 and rect2 I saw that there size was a percentage of the window. These are the codes for the two rectangles:
      canvas.coords('rect1',.2*WINDOW,.05*WINDOW,x,.2*WINDOW)
      canvas.coords('rect2',x,.05*WINDOW,.9*WINDOW,.2*WINDOW)
By changing these numbers I changed the size of the rectangles.

I than changed how to close the program, it closed down when I pressed q but I changed that code to the letter e just to change it. You can see in the top left corner of the screen below that it says (e to exit).
Now I wanted to make a different shape than a rectangle so I did some Google research on how to make a circle in python. The circle is called oval in python so I made a new object under the rectangle. Here is the code:

       canvas.itemconfigure('oval1',2*WINDOW)
Here you can see the blue circle in the top corner

The circle moved as the txrx responded to conductivity.

The last thing I did was that I made a yellow screen with a small, thin line, that showed the conductivity. I took out the text and here are pictures of the outcome:

hello.button

In the input week two weeks ago I made this hello.button switch and I wanted to change the codes for it. If I pressed the button in the original file I got the letters d and u for up and down. I wanted to see something else happen so I changes the codes from:
      ;put_char(&serial_port, serial_pin_out, 'd')
to:          
while (0 != pin_test(input_pins,input_pin))
        ;put_char(&serial_port, serial_pin_out, 'b')
	;put_char(&serial_port, serial_pin_out, 'j')
	;put_char(&serial_port, serial_pin_out, 'a')
	;put_char(&serial_port, serial_pin_out, 'r')
	;put_char(&serial_port, serial_pin_out, 't')
	;put_char(&serial_port, serial_pin_out, 'u')
	;put_char(&serial_port, serial_pin_out, 'r')
	;
      //
By doing this I changed the d that came when I pressed down to my name bjartur. I did the same thing with the u and changed it to tyr, my middle name. 

      ;put_char(&serial_port, serial_pin_out, 'u')
to:          
while (0 != pin_test(input_pins,input_pin))
        ;put_char(&serial_port, serial_pin_out, 't')
	;put_char(&serial_port, serial_pin_out, 'y')
	;put_char(&serial_port, serial_pin_out, 'r')
	;
      //
Here is the program running
