code check for me please

hello everyone i am in the middle of making a LED screen for a project that needs to show a different image for each separate button press.
i will have 5-6 buttons.
5-6 images.
i have figured out how to code out the images and have gotten them to display properly on the 16x24 display that i have.

now what i need to know is:
a. how to add button presses to the code to make them "if statements" (??)
b. how to upload the code to the arduino to make it portable. (already have it powered up w/ battery pack but i would like to have the code be onboard so i dont have to upload from computer)
-also afraid i will overwrite something important if my code doesnt have everything...
c. there has got to be a way to make this code better, but right now everything fits just fine so i guess its ok.
d. im guessing im going to need to incorporate an on/off switch into this too

and yes i am very new to this. but hot damn- i have all this written and i picked this up 2 days ago

code in next post

thats all the code

Can I recommend you read about for loops?
They'll make your code shorter and easier to debug

system · April 21, 2012, 11:27am

i would make a table with the positions in it. like this:

int table2[8] = { 8,2 , 9,2 , 14,2 , 15,2 };

and then draw them with a for loop as AWOL said:

for (int i=0; i<= 7; i+=2)  {
     matrix.drawPixel(table2[i],table[i+1],2);
}

im not gonna lie, i have no idea how i would use them.

but im not really going to need to shorten the code unless adding the buttons i want is going to double the amount of code. (size doesnt seem to be an issue ATM)

thanks for the loop and table info though, can i get an example of what would convert into what?
if it helps the 16x24 is 6 separate 8x8 grids wired together

i have no time atm, but i'll take a look at the whole code this evening. to add the buttons, just make a variable (preferable int ) that saves the mode it isin atm, like this:

int dispMode = 0;
//setup here
void loop() {
   if (digitalRead(pinToReadHere) == HIGH) {
      dispMode++;
      if (dispMode>=amountOfModes) {
         dispMode=0;
      }
   }
   if (dispMode == 1) {
      //Here comes the first drawing routine (the big zero)
   }
   else if {dispMode == 2) {
      //Here comes the second drawing routine
   }
   //etc.
}
}

and this is where the handy part about the table comes in too. Instead of doing these if statement to check the value of dispMode, you could make one table with all the vars in it, and have a pointer to the place in the table. (this sounds weird maybe).

so, you've got a table with all the variables inside (like in my previous post). All the values are inside that one table (of all the routines), so you just have to keep another table that keeps an index of where to start looking for data in the first table, got it? this might be totally overruled, but i think this is a good approach and it will save space (even if you don't want to xp )

thanks for looking at the code. i tried implementing it into my code to no avail.

im taking a good look at the arduino tutorials while waiting for your response.

thanks again.

Check this link too

looks promising but can i use c++ in arduino straight away? or do i need to tell it im using a different code?

system · April 22, 2012, 8:02am

You are using C++

system · April 22, 2012, 8:33am

man, as if i didnt oust myself as a noob enough in the first post.

heres an update though! i got buttons working!!
as soon as i get everything all wired up i might not have anymore questions!

Edit: yep totally figured it out. just need to buy real buttons to replace the wire contacts i made....

system · April 24, 2012, 11:37pm

instead of making a new thread....

everything works now but im having trouble making the buttons interrupt each other

i tried the blink without delay tutorial but i cant seem to figure out how to work it into my 6 button program
