7 segment display

[stas054]

What is it you are trying to achieve?
Hello everyone, I am making a test program with ultiple choice questiongs that works from a joystick I made.


What is the problem you are having?
I am having a problem with programming 7 segment display, it supposed to work as a countdown from 9 to 0 but it just puts random numbers and I don't get how it works exactly, can somebody explain to me? or give me a sample code for countdown on 7 segment from 9 to 0 using parallelput?


Describe what you have tried to solve this problem
I tried pretty much everything I found even putting something like parallelput(22) and it actually gave me numbers but I don't get the pattern

Turing:

%display functions %0 parallelput (1) parallelput (2) parallelput (4) parallelput (16) delay (1000) %1 parallelput (2) parallelput (4) parallelput (16) delay (1000) %2 parallelput (1) parallelput (4) parallelput (16) delay (1000) %3 parallelput (4) parallelput (16) delay (1000) %4 parallelput (1) parallelput (2) parallelput (16) delay (1000) %5 parallelput (2) parallelput (16) delay (1000) %6 parallelput (1) parallelput (16) delay (1000) %7 parallelput (16) delay (1000) %8 parallelput (1) parallelput (2) parallelput (4) delay (1000) %9 parallelput (2) parallelput (4) delay (1000)

Please specify what version of Turing you are using
4.1.1

read the docs on parallelput. In brief, with parallelput(22), you are not putting 22, but the binary string that 22 represents 0010110 -- match up 7 bits to your 7 segments, and you should figure out the patterns that will draw digits on the screen.

I got it now... but... I am only using 4 outputs so that would be 0000 for 0 0001 for 1, 0010 for 2 and so on, but it doesnt seem to work =/

I mean it works but I am getting random numbers not the ones I need

[stas054]

this is what I did

Turing:

parallelput(6) delay(1000) parallelput(7) delay(1000) parallelput(8) delay(1000) parallelput(9) delay(1000) parallelput(10) delay(1000) parallelput(11) delay(1000) parallelput(12) delay(1000) parallelput(13) delay(1000) parallelput(14) delay(1000) parallelput(15) delay(1000)

but it doesn't work properly =(

[Tony]

what do you mean it doesn't work properly? What do you expect to be the proper result, and how is the observed behaviour different?

[stas054]

well it starts with 9 and then it displays random parts of the 7 seg... I don't understand why it does that if I look at the theory I have done everything correctly...

[stas054]

i want it to count... 9...8...7...6...5...4...3...2...1...

nvm I got it thanks xD
