Need help with arrays
PostPosted: Tue Jul 03, 2012 9:37 am     Reply with quote
Hello,

I want to make a tetris game in ccs but I have a problem because SOME LEDS are permanent on.

I made an array and set everything to false:
Code:

int1 Pixel[16][8] = {{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0},{0,0,0,0,0,0,0,0}};

Then when I create the condition all Leds are on:
Code:

for(x = 0; x < 16; x++)
{
   for(y = 0; y < 8;y++)
   {       
      if(Row[x][y] == 1 || Pixel[x][y] == 1)
      {
         TurnLedOnByCoords(x+1,y+1);             
      }                   
   }
}

The function of TurnLedOnByCoords:
Code:

void TurnLedOnByCoords(int row, int col)
{
  if(row <= 7 || col <= 5)
  {
   if(row==1) output_high(PIN_A0);
   if(row==2) output_high(PIN_A1);
   if(row==3) output_high(PIN_A2);
   if(row==4) output_high(PIN_A3);
   if(row==5) output_high(PIN_A4);
   if(row==6) output_high(PIN_A5);
   if(row==7) output_high(PIN_B0);
   
   if(col==1)output_high(PIN_D4);
   if(col==2)output_high(PIN_C6);
   if(col==3)output_high(PIN_D5);
   if(col==4)output_high(PIN_B3);
   if(col==5)output_high(PIN_C5);

   
   delay_us(250);
   
   if(row==1) output_low(PIN_A0);
   if(row==2) output_low(PIN_A1);
   if(row==3) output_low(PIN_A2);
   if(row==4) output_low(PIN_A3);
   if(row==5) output_low(PIN_A4);
   if(row==6) output_low(PIN_A5);
   if(row==7) output_low(PIN_B0);
   
   if(col==1)output_low(PIN_D4);
   if(col==2)output_low(PIN_C6);
   if(col==3)output_low(PIN_D5);
   if(col==4)output_low(PIN_B3);
   if(col==5)output_low(PIN_C5);
  }
}


This function for turning on the leds is right because I use it in another project.

I hope that someone can help me.

The obvious question would be:

What is in
Code:
Row[x][y]
???

a 0 or a 1

for example:

Code:
    Pixel[0][3]=true;
          Pixel[0][4]=true;
          Pixel[1][3]=true;
          Pixel[1][4]=true;


When i use BYTE instead of Boolean it works but thats not the way its only true and false that i need.

Thanks for the explanation of "Pixel[][]".... which is _not_ "Row[][]".....

... sigh.

Row[][] is a bool array just ignore Row because when for example Pixel[0][5] is set to true the led in Row 1 and Col 5 Should normally be on but the problem is that everything is on then. When I use byte instead of Boolean it works so how can i do it with boolean because otherwise the array is to big and i get an error that there is no space for all variables.

I hope you understand it.

Hi,

Please repeat after me; always post your compiler version. Some compiler features have known issues with some versions, so this is critical information. See this post for more information on this issue: http://ccsinfo.com/forum/viewtopic.php?t=48363&highlight=int1+array

Two-dimensional arrays of bits (int1) probably don't work in your version:

They may not work in any version.

I'm totally lost. I can't even start to understand what you are doing.

Please supply schematic for LEDs, shortest possible complete compilable code which CLEARLY illustrates problem, a lucid account of what does/doesn't should/shouldn't happen, and compiler version etc.

from the looks of it he is trying to drive a LED matrix ("screen")
and set each "pixel" individually...



...
its easier if you set each column or row a full byte and write entire columns or rows at the same time... you can address "pixels" individually as well with this byte aproach...
