If I understand correctly, this thread is an example. http://arduino.cc/forum/index.php/topic,132180.0.html

Well they are both excellent examples of how not to ask a question.
A question has to convey enough information for a reader to understand the situation. Posting without punctuation is one way of making things incomprehensible.

i am making a custom code scanner using 2 rows of black and white the bottom row is black white black white etc it is 8 bit so 4 white 4 black
...
dude you do understand my sentences without capitals, like i said.

He wants help, but first, he isn't prepared to use capitals or punctuation, and second, he insults the people he wants help from.

I said this to him:

I really don't know what you are trying to do. You are doing an SPI.transfer in the middle of the ISR?

You send back data to the master by assigning to SPDR in the interrupt service routine. No other way. What are you thinking?

So what does he do?

Code:
if(c == 0x04)
  {
    digitalWrite(SS, LOW);
  SPI.transfer(dat[0]);
  SPI.transfer(dat[1]);
   digitalWrite(SS, HIGH);
  
   digitalWrite(SS, LOW);
  SPI.transfer(dat[2]);
  SPI.transfer(dat[3]);
   digitalWrite(SS, HIGH);
  
   digitalWrite(SS, LOW);
  SPI.transfer(dat[4]);
  SPI.transfer(dat[5]);
   digitalWrite(SS, HIGH);
 }
 
  else if(c == 0x06)
  {
   digitalWrite(SS, LOW);
  SPI.transfer(dat[6]);
  SPI.transfer(dat[7]);
   digitalWrite(SS, HIGH);
  
   digitalWrite(SS, LOW);
  SPI.transfer(dat[8]);
  SPI.transfer(dat[9]);
   digitalWrite(SS, HIGH);
  
   digitalWrite(SS, LOW);
  SPI.transfer(dat[10]);
  SPI.transfer(dat[11]);
   digitalWrite(SS, HIGH);
 }

That falls into the category of "another way".

Here's the problem, Rob.

He'll thank you. He'll totally change what you did into something completely different. He'll take a screenshot of the output of his new, incorrect code. And he'll ask what is wrong. He's been doing that since August.

Yeah, I've been watching, which makes me doubly stupid smiley I'll give him a few responses then bow out if he's not being lucid. Life's too short.
