Help with project, PIC 18F4550 , regularly spotlight

[Macko77]

Good , 'm doing a light control system as an integration of matlab and acquisition board with 18F4550 , through matlab the idea is to send a character to the pic then the control part , the card takes off and 3 shares on two campuses and light of one of the enclosures control the first two things are already made but I can not perform the action of light control , the code that I take is as follows:

# include < 18F4550.h >
# fuses HSPLL , MCLR , NOWDT , NOPROTECT , NODEBUG , USBDIV , PLL5 , CPUDIV1 , VREGEN , NOPBADEN , NOLVP
# use delay (clock = 20000000 )
# use fast_io ( A)
# use standard_io (B )
# include " usb_cdc.h " / / USB Function description in quotation marks because it is working on same folder
# include " usb_desc_cdc.h " / / USB device descriptors .

void main () {
   int salt1 , sal2 ;
   unsigned char datoIN ;
   usb_cdc_init ( ) / / Configure the virtual port.
   usb_init ( ) / / Initialize the USB stack.
   set_tris_A (0xFF ) / / I set port A as inputs
   set_tris_B ( 0x00 ) / / I set the output port b
    
   while (! usb_cdc_connected ())
   {
      Output_high ( PIN_E0 ) ;
      Output_low ( PIN_E1 ) ;
      Delay_ms (500);
      Output_high ( PIN_E1 ) ;
      Output_low ( PIN_E0 ) ;
   }
   / / Wait to detect a transmission from the PC ( Set_Line_Coding ) .
   
   Output_high ( PIN_E0 ) ;
   Output_low ( PIN_E1 ) ;
  
   salt1 = 0 / / initialized alternative Variables
   sal2 = 0 / / initialized alternative Variables
  
  do {
      usb_task ( ) ;
         / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / /
            
      if ( usb_enumerated ())
      { / / Wait for the device to be enumerated by the host.
         Output_low ( PIN_E0 ) ;
         Output_high ( PIN_E1 ) ;
         if ( usb_cdc_kbhit ())
         { / / Pending new characters in the receive buffer .
            usb_cdc_getc datoIN = ( ) ;
            if ( datoIN == ' a')
            { / / What came was the character a = no movement in the room 1 and was the highest intensity ?
            Output_high ( PIN_B0 ) ;
            salt1 = 1 / / if, then the lights are turned one room
            }
            if ( datoIN == ' b')
            { Val = 8;
            }
            if ( datoIN == ' c')
            { Val = 7;
            }
            if ( datoIN == ' d')
            { Val = 6;
            }
            if ( datoIN == ' e')
            { Val = 5;
            }
            if ( datoIN == ' f' )
            { Val = 4;
            }
            if ( datoIN == ' g')
            { Val = 3;
            }
            if ( datoIN == ' h')
            { Val = 2;
             }
            if ( datoIN == ' i')
            { / / What came was the character b = no movement in the salon 1 ?
            Output_low ( PIN_B0 ) ;
            }
            if ( datoIN == ' j' )
            { / / What came was the character c == no movement in the salon 2 ?
            Output_high ( PIN_B1 ) ;
            sal2 = 1 / / if, then the lights are lit room 2
             }
            if ( datoIN == ' k')
            { / / What came was the character d = no movement in the salon 2 ?
            Output_low ( PIN_B1 ) ;
            }

            if ( salt1 == 1 | | sal2 == 1 ) / / ask for variable room
            {
            Output_high ( PIN_B2 ) / / Runs Led Indicator
            }
            else
            {
            Output_low ( PIN_B2 ) / / Runs Led Indicator
            }
           datoIN = data ;
           }
      }
  } while ( TRUE ) / / infinite loop.
}


The idea is when the data q [b ] b come [/ b] the intensity is 90 % on pin B0 , when you get [b ] c [/ b] the intensity is 80% on pin B0 , when you get [b ] d [/ b] the intensity is 70 % on pin B0 , when you get [b ] e [ / b ] the intensity is 60 % on pin B0 , when you get [b ] f [/ b] intensity is 50% on pin B0 , when you get [b ] g [/ b] the intensity is 40% on pin B0 , when you get [b ] h [/ b] the intensity is 30% in the pin B0 .


I write porq I have tried many things but I do not get what I want , and this is part of my thesis to qualify for the title of telecommunications engineer , and I need it , not if someone could colaborarme or help to implement it.

This is the dogs in general, the moc I use the 3020 q and zero crossing triac BT136

I would appreciate a prompt response

1) Learn to use the code buttons.
2) Clock rate is not 20MHz.
This has been posted only a couple of days ago.
If you want to run at 20MHz, then with a 20MHz crystal:

There are a bunch of statements missing the terminating semi-colon. I'm wondering just what the compiler does with those ? (most compilers wake up some number of lines after the errors when they realize they are really confused - it takes a while to figure out just where the original confusion started sometimes!! )

[Macko77]

excuse me my mistake was a correct statement is:

datoIN = usb_cdc_getc ();

datoIN is a variable to load the character sent from matlab, the empty characters b, c, d, e, f, g, h, i, are the percentages of intensity of light.

Ie when the character 'b' comes, the light-controlled (pin b0) must be 90%, if it 'c', the percentage should be 80%, if it 'd' the percentage is 70% and so on.


What is not is how to do that!

[gpsmikey]

To do the percentage of light you want, you will need to use "phase control" assuming you are working with AC mains. You need to spend some time searching the forum here as well as other resources to figure out how to implement phase control. It involves zero crossing detection as well as delay times.
