| problem with sequence running [solved] |

I am having a problem getting this code to work to run the sequence as I have it loading. I am trying to flash 8 leds on port b of a pic16f628. I have had it working other ways but wanted to make the c code smaller.
| Code: |
#include <16F628A.h>
#fuses INTRC_IO,NOPROTECT,NOWDT,PUT,NOMCLR
#use delay(clock=4000000)
#use standard_io(b)
#byte port_b = 6
char rom led_tab[] = {0x00,0xFF,0x00,0xFF,0x00,0xFF,0xFF,0x00,
0x7F,0xBF,0xDF,0xEF,0xF7,0xFB,0xFD,0xFE,
0x7F,0xBF,0xDF,0xEF,0xF7,0xFB,0xFD,0xFE,
0x7F,0xBF,0xDF,0xEF,0xF7,0xFB,0xFD,0xFE,
0x7F,0xBF,0xDF,0xEF,0xF7,0xFB,0xFD,0xFE,
0xFE,0xFD,0xFB,0xF7,0xEF,0xDF,0xBF,0x7F,
0xFE,0xFD,0xFB,0xF7,0xEF,0xDF,0xBF,0x7F,
0xFE,0xFD,0xFB,0xF7,0xEF,0xDF,0xBF,0x7F,
0xFE,0xFD,0xFB,0xF7,0xEF,0xDF,0xBF,0x7F,
0x7E,0xFF,0x7E,0xFF,0x7E,0xFF,0x7E,0xFF,
0xBD,0xFF,0xBD,0xFF,0xBD,0xFF,0xBD,0xFF,
0xDB,0xFF,0xDB,0xFF,0xDB,0xFF,0xDB,0xFF,
0xE7,0xFF,0xE7,0xFF,0xE7,0xFF,0xE7,0xFF,
0xE7,0xFF,0xE7,0xFF,0xE7,0xFF,0xE7,0xFF,
0xDB,0xFF,0xDB,0xFF,0xDB,0xFF,0xDB,0xFF,
0xBD,0xFF,0xBD,0xFF,0xBD,0xFF,0xBD,0xFF,
0x7E,0xFF,0x7E,0xFF,0x7E,0xFF,0x7E,0xFF};
void main(void)
{
set_TRIS_B(0x00); /* set port_b to be outputs */
PORTB = 0; /* initialize All port_b outputs to be zero */
while( TRUE )
{
/* forever loop using WHILE construct */
char i;
for(i=0; i<136; i++)
{
PORTB = led_tab[i];
delay_ms(100);
}
}
}
|
when i run the above code in proteus all it does is all 8 leds light up and stay lit .and when i wrote it to the pic and tested it it does the same in hardware as well. |

| Got it fixed after posting changed from char rom to char const and fixed my portb it should be port_b issue in the main code. |

Thanks Joe! I am sure it will be beneficial to some of the folks here and
future visitors. Maybe a copy could be put in the Code Library?
