optimization

hello

I have a display max7219 my code looks like its

Write_Max7219 (1, B00000000); 
Write_Max7219 (2, B00000000);
Write_Max7219 (3, B00000000);
Write_Max7219 (4, B00000000);
Write_Max7219 (5, B00000000);
Write_Max7219 (6, B00000000);
Write_Max7219 (7, B00000000);
Write_Max7219 (8, B00000000);

I do not know if it is clear what I want to do my roughly be able to optimize the first code by something more compact like its return
often
is it possible to modify it in this style

for (int i =1; i <=9; i++{
  Write_Max7219(i, B00000000);
}

yes. the loop is a good idea. values can be computed from the loop index. You save code space for each function call.

but if the values were unique, you could create a table of structures where each table entry is integer and binary value and you loop thru the table pulling values.

Those pieces of code are not equivalent. The for loop goes from 1…9 but your original code goes from 1…8.
Also, B00000000 is the binary representation of 0 so why not just use that?

for (int i =1; i <9; i++{
  Write_Max7219(i, 0);
}

i forgot to say my i9 serve me for something else after thanks to both of you will help me save :)
