Dear reader,

     I looked at several sources for a simple routine(All signal
     processing done in a 16f628a):

          1. Receive a button-press-caused infrared-signal from a
          remote control with a TSOP1740(IR receiver module)

          2. Identify the button being pressed. Then return a number
         representing the button being pressed.

     I want to go into detail about my experiences: There are all
     kinds of code-examples, everytime combined with varieties of
     hardware. No simple routine to call and get the values needed.
     Not at all. It seems to me as if the creators of theses codes
     have never ever reached adulthood. And this is meant in a
     negative way. All comments I have read in the code are totally
     useless as they describe what everyone has already noticed.

     For example(in picbasic): "PORTA = PORTA >> 1 & %00001111  'PORTA
     moving 1 to the right whereas bit 4 to 7 are hidden." Totally
     useless. I am asking WHY this is done exactly there to get a clue
     what to delete or expand and not what it does.

     On and on combined with displays and their driving, fancy
     joysticks(which, of course, need their own driving, and this is
     included in the code somewhere aswell, without any explaining
     what is done there).

     What I want is the routine mentioned. And a _good_ documentation,
     if there are any modifications necessary. A documentation which
     does not require the user to rewrite the code just because the
     writer thought of himself as a teacher who thought of himself to
     be selected to teach everyone. I don't want to learn anything
     because someone decides he is in need to teach without asking for
     permission (!) (because noone ever would ask exactly those people
     for a lesson).

     Look at references for python for example. Plain and clear
     routines, only necessary values to be passed and a useful result.
     THIS is why it is popular.

     No playground. And I say this with conviction even though I am
     creating a hobbiist project.
