Hi, MTripoli

As I fully do understand your point of view, as I am surprised by it's violence may I say INNOCENCE ...

What you describe have been observed for years in many specialities , and of course in workplaces and universities.

Some kind of Internet spread desease ??? ... may be ...

Everyone ( not exactly everyone ... Thanks to god ! ) " copies and Pastes " , ask for Instructables, Videos and , of course a touch of customization ... just to be able to tell bar-friends " I DID IT " ... or pass their exams !!!

One of our greatest actor ( Jean Gabin ) was saying, 40 years ago, in " Les tontons flingueurs " , famous comic film about papies ripping off :

" Bloody stupid people dare to do anything ... thats also how one can recognize them. "
... yeah, your right, sad world.

I gently would answer you ...

As you are not paid in any way here ... you're not to answer any query ...

Just keep in mind everything placed on the Web can be " stolen " ...
Copyright ??? ... just a view of mind !!!

MTripoli is correct.

I recall reading a paper not so long ago written by a UNI professor regarding his concerns with all of this. Copy & paste to do assignments. Where's the world headed?

Anyhow here's a glimpse at some C code:

/*
   8-LED Knight Rider Scanner    
   MCU: PIC16f877a
   
   Requirements:
      1. Connect 8 leds to portC
      2. 1 x push button to RB1 with pull up resistor
      3. 4MHz XTAL
   
   Usage:
     Pressing the switch causes the leds to chase back & forth   
*/

// Global scope variables
char i = 0; // Direction of scan
char j = 1; // Gen working var
char k = 0; // Gen working var

void main()
{
  TRISA = 0x00;      // PortA as output
  TRISB = 0x02;      // RB1 to as input rest as out
  TRISC = 0x00;      // PortC as output
  TRISD = 0x00;      // PortD as output
  TRISE = 0x00;      // PortE as output
  PORTC = 0x00;     // Init port, all pins low

   // Infinite loop
   while(1)
   {
      if (PORTB == 0)        // Button pressed?
      {

         PORTC = j;            // Write to port
         delay_ms(100);      // 100mS delay
         
         // Scan dir forward //

         if (i == 0)
         {
            j = (j << 1);       // Shift bits left
         }
         
         // Scan backward //

         else
         {
            j = (j >> 1);    // Shift right
         }

         // Toggle direction //

         k ++;                   // Inc counter
         
         if (k == 7)           // Counter reached n val?
         {
            k = 0;              // Reset
            i = ~i;             // Toggle dir
         }
      }
   }
}

Not much more involved than BASIC. The help file in MikroC is great, if that fails then go and buy a book. If that fails too, then go and do some formal study.

"Violence" may not be the correct translation (I see you are from France - God I love the food there; I 've spent some time in Pau at Elf Aquitane many years ago. The Pyrenees mountains are stunningly beautiful). How about "frankness" or "forthrightness" (franchise?).

I wasn't answering any query. I was stating my opinion.
