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
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 =/ |

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? |

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... |
