ineffecient to access arrays out of sequence

-
basically little observation made when accessing arrays out of sequence. i had inside isr, , affected performance worse. found pretty strange code little bit of isr. tried have array element 2 @ top (not important @ of course). code: [select]  for ( int x=0 ; x<4 ; x++ )  {    for ( int y=0 ; y<4 ; y++ )    {      int cx = x+1;      int cy = y+1;      int fivecy = 4 - y; // 5-cy      face[2][x][y] = cube[cx][fivecy][0]; // top (face 2)      face[0][x][y] = cube[5][cx][cy];      face[1][x][y] = cube[cx][0][cy];      face[3][x][y] = cube[0][cx][fivecy];      face[4][x][y] = cube[fivecy][5][5-cx];      face[5][x][y] = cube[cx][cy][5]; // bottom (face 5)    }  } putting in sequence made faster again. thought wouldn't matter, guess compiler optimizations when arrays accessed in sequence? i have since optimized isr ~40% latency, these 2 versions (array in sequence vs out-of-sequence), had latency of 53 timer2 clock cycles (86% latency) , (see...

A question about file extentions of tabs in IDE.

Image
 i'm starting write larger sketches , finding out how important organization of code larger program becomes. i'm using arduino ide compsose code , started using tabs break code semi-managable chunks. when named tabs didn't give extention names (didn't know could). ide treat code if 1 big file.  then learned little making them header files , "#include"ing them main sketch enables me isolate different sections of code , localize variables within them. useful!  somewhere in learning section on arduino site  i came accross - tabs, multiple files, , compilation: allows manage sketches more 1 file (each of appears in own tab). these can normal arduino code files (no extension), c files (.c extension), c++ files (.cpp), or header files (.h).  my question is, difference/use of using .c or .cpp extentions in tabs of arduino ide. there benifit in doing that. know libraries have have both .h , .c files. better off learning how write libraries. which, way, li...
