Embedded C Dev Kit
PostPosted: Wed Oct 23, 2019 9:31 am     Reply with quote
I am working through the examples/lessons and during lesson 7 i am not able to get the 7 segment display to light up. I am not seeing any errors when i build/compile and run the program.
Code:

/*     ccscana.c     */
#include <18f45k80.h>
#device ICD=TRUE
#fuses NOPROTECT,NOWDT
#use delay(clock=64MHz,crystal=16MHz)

#define CAN_BRG_PRESCALAR        15
#define CAN_BRG_PHASE_SEGMENT_1  6
#define CAN_BRG_PHASE_SEGMENT_2  6
#define CAN_BRG_PROPOGATION_TIME 0
#define CAN_BRG_SYNCH_JUMP_WIDTH 0
#include <can-18F4580.c>

#define WRITE_REGISTER_D_ID 0x400

void write_7_segment(int value) {
   const int lcd_seg[10]={0x40,0x79,0x24,0x30,0x19,
                          0x12,0x02,0x78,0x00,0x10};
   int buffer[3];
   
   buffer[0]=0x1E;
   buffer[1]=0x7F;
   buffer[2]=lcd_seg[value];
   can_putd(WRITE_REGISTER_D_ID,buffer,3,1,TRUE,FALSE);
}


/*      ex6.c        */
#include "ccscana.c"

void main(void){
   int i=0;
   
   can_init();
   can_putd(0x100,0,0,1,TRUE,FALSE); //send an on-bus message
                                     //to wake up MCP250x0's
   delay_ms(1000);                   //wait for node c to power-up
   
   while(true){
      write_7_segment(i);
      delay_ms(1000);
      if(++i==10)
         i=0;
   }
}

What CCS development board do you have ?

What book do you have ? What chapter or page number are you looking at ?

ICD-U64 with Development Kit for the PIC MCU. The Can BUS exercise book, Example number 6.

The board has the 18F45k80 and the 16f1936 nodes and a MCP2515 and MCP25050 chip on there.

The only manual I can find for this board on the net has a 2010 date.
The board you have is a newer model. So I don't think I can help.
I suggest you contact CCS support.
