Trying to learn CCS : 7-segment

[New_Convert]

This is following the sample code from CCS to drive a 7-segment display.
My question is, why doesn't using #use fast_io() and set_tris_x() work?

#use_fast_io(B)
#use fast_io(C)

set_tris_b(0x00);
set_tris_c(0xFC);


I tried putting a bit of delay between switching of specific bits but to no avail.


This is the code that works pefectly by standard_io. Using fast_io I noticed that RB<0:7> and RC<0:1> could never go HIGH.


#include <16f877.h>
#fuses HS, NOLVP, NOWDT, PUT
#use delay(clock=20000000)

byte CONST LED_MAP[10] = {0x3f, 0x06, 0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x67};

void display_number(int n)
{
output_b(LED_MAP[n/10]);
output_low(PIN_C0);
delay_ms(2);
output_high(PIN_C0);
output_b(LED_MAP[n%10]);
output_low(PIN_C1);
delay_ms(2);
output_high(PIN_C1);
}

void main()
{
int count=1, i;

while(1)
{
for(i=0; i<=200; i++)
{
display_number(count);
}
count = (count==99) ? 1: count+1;

}
}

[PCM programmer]

Post the code that doesn't work. Post it as a complete program.
(ie, the same way as the working code, showing #fuse statement, etc.).

I got it working. Thank you.
