Problem with robot program select menu

I have a problem with programming a menu for selecting my programs for my robot.

The program has to show 9 numbers from 1 to 9 on a 7-segment display, representing a program(avoidance, linefollowing,....)

With 2 switches you go up or down a number and you comfirm with the 3the button(selecting the program you want). The 3 buttons are 1 input that gives a different value depending which button is pressed.

 

Now, the program I have written( in C) only gives a 9 when I start up the robot(not 1 of the buttons has effect on the numer appearing). I was wondering if you guys would help me find the solution to my robots problem.

Thanks, Danny

 

Here is my code.

void ShowNumber(void)
    {
    if(Number=1)
    {
        NumberOne();// Is showed on the display
    }
    if(Number=2)
    {
        NumberTwo();// Is showed on the display
    }
    if(Number=3)
    {
        NumberThree();// Is showed on the display
    }
    if(Number=4)
    {
        NumberFour();// Is showed on the display
    }
    if(Number=5)
    {
        NumberFive();// Is showed on the display
    }
    if(Number=6)
    {    
        NumberSix();// Is showed on the display
    }
    if(Number=7)
    {    
        NumberSeven();// Is showed on the display
    }
    if(Number=8)
    {    
        NumberEight();// Is showed on the display
    }
    if(Number=9)
    {
        NumberNine();// Is showed on the display
    }
    
    }    

void Choseprogram(void)
    {
    keuzesensor=a2dConvert8bit(3);
    while(keuzesensor < 150 || keuzesensor > 110)// If the confirmbutton isn't pushed
    {
    keuzesensor=a2dConvert8bit(3);
    
    if(keuzesensor > 170 && keuzesensor < 210)//1ste button
    {
    Number+=1;
    delay_cycles(10500);
    }
    
    if(keuzesensor > 60 && keuzesensor < 90)//second button
    {
    Number-=1;
    delay_cycles(10500);
    }
    
    if(Number> 9)
    {
    Number=9;
    }
    
    if(Number< 1)
    {
    Number=1;
    }
    
    ShowNumber();
    delay_cycles(1000);
    }

You need the double equals

You need the double equals sign for comparing.

if (Number==1)…

Did you do debounce of

Did you do debounce of button?

You might also be better off

You might also be better off with a switch case statement

http://www.arduino.cc/en/Reference/SwitchCase

You can also change;

if(Number> 9)
    {
    Number=9;
    }

to

if (Number > 9) Number = 9;

for a more compact syntax.

== should be used, put a

== should be used, put a 10nF cap in paralel with the button for debounce and you could simply use a switch - case statement and change the button counter in an interrupt

yeah

yeah that what the delay is for.

Thanks

The robot menu works fine now.

Gonna finish all the different programs now(line following, avoidance, wall following,…)

Thanks for all the advice.

hm my line following code

hm my line following code for 5 sensors eats up 4kb of flash of 8kb… :expressionless: wonder how will you make those 9 menus even with LCD library too

No LCD

I don’t use an lcd, just 1 7-segment led display.

thats seven ports no matter

thats seven ports no matter how I calculate… or do you use register shifter via I2C?

I use a driver chip

This chip turn 4 outputs(BCD) from my microcontroller in outputs for the 7-segment display.
