How to expand the control leds on PIC-MAXI-WED?
« on: March 15, 2016, 04:49:15 AM »
I want to add the LED driver but when control led10 it came back led1 (not control led10)?, despite repair code in the file:
HWP...h:
// I/O pins
   #define LED0_TRIS         (TRISJbits.TRISJ0)   
   #define LED0_IO            (PORTJbits.RJ0)
   #define LED1_TRIS         (TRISHbits.TRISH3)   
   #define LED1_IO            (PORTHbits.RH3)
   #define LED2_TRIS         (TRISBbits.TRISB0)   
   #define LED2_IO            (PORTBbits.RB0)
   #define   LED3_TRIS         (TRISBbits.TRISB1)   
   #define LED3_IO            (PORTBbits.RB1)
   #define   LED4_TRIS         (TRISBbits.TRISB2)   
   #define   LED4_IO            (PORTBbits.RB2)
   #define   LED5_TRIS         (TRISBbits.TRISB3)   
   #define   LED5_IO            (PORTBbits.RB3)
   #define   LED6_TRIS         (TRISGbits.TRISG6)   
   #define   LED6_IO            (PORTGbits.RG6)
   #define   LED7_TRIS         (TRISGbits.TRISG5)   
   #define   LED7_IO            (PORTGbits.RG5)
   #define   LED8_TRIS         (TRISGbits.TRISG4)   
   #define   LED8_IO            (PORTGbits.RG4)
   #define   LED9_TRIS         (TRISFbits.TRISF7)   
   #define   LED9_IO            (PORTFbits.RF7)
   #define   LED10_TRIS         (TRISGbits.TRISG7)   
   #define   LED10_IO         (PORTGbits.RG7)

CustomHTTPApp.c: 
                ptr = HTTPGetROMArg(curHTTP.data, (ROM BYTE *)"led10");
                if(ptr)
         LED10_IO = (*ptr == '1');
           ptr = HTTPGetROMArg(curHTTP.data, (ROM BYTE *)"led9");
      if(ptr)
         LED9_IO = (*ptr == '1');
      ptr = HTTPGetROMArg(curHTTP.data, (ROM BYTE *)"led8");
      if(ptr)
         LED8_IO = (*ptr == '1');
      ptr = HTTPGetROMArg(curHTTP.data, (ROM BYTE *)"led7");
      if(ptr)
         LED7_IO = (*ptr == '1');   
      ptr = HTTPGetROMArg(curHTTP.data, (ROM BYTE *)"led6");
      if(ptr)
         LED6_IO = (*ptr == '1');
      ptr = HTTPGetROMArg(curHTTP.data, (ROM BYTE *)"led5");
      if(ptr)
         LED5_IO = (*ptr == '1');
      ptr = HTTPGetROMArg(curHTTP.data, (ROM BYTE *)"led4");
      if(ptr)
         LED4_IO = (*ptr == '1');
      ptr = HTTPGetROMArg(curHTTP.data, (ROM BYTE *)"led3");
      if(ptr)
         LED3_IO = (*ptr == '1');
      ptr = HTTPGetROMArg(curHTTP.data, (ROM BYTE *)"led2");
      if(ptr)
         LED2_IO = (*ptr == '1');
      ptr = HTTPGetROMArg(curHTTP.data, (ROM BYTE *)"led1");
      if(ptr)
         LED1_IO = (*ptr == '1');
.......................
MainDemo.C:

Looking forward to your help. Thanks.

Hi,

I think here are some lines missing from your post:
CustomHTTPApp.c:
... <= here
         LED10_IO = (*ptr == '1');
           ptr = HTTPGetROMArg(curHTTP.data, (ROM BYTE *)"led9");
      if(ptr)

Could you please add this missing lines to the post, so that we can be sure that the check is properly implemented?

But I think the check will be fine, and the problem is hidden somewhere. I think on the following thing: Everything works fine until the LED numbers are 1 digits. When a LED with two digits came into play, then some buffer is not properly erased or handled and that is why somewhere in the software a check is thinking that it found LED 10 but in reality it is LED1 (plus a remaining 0 from the last check). So you should debug the function HTTPGetROMArg and look for a buffer which is not complety erased.

As an alternative (workaround) you can try to renam the LED from led10 to leda, to see if it is working. I guess it will.
