anybody can help me to fix this program,..
#include<16f877.h>
#fuses XT,NOLVP,NOWDT,PUT
#use delay (clock=1M)
#byte port_d=8
#byte port_a=5
#byte port_c=8
byte CONST LED_MAP[10]={0x3F,0x06,0x5b,0x4F,0x66,0x6D,0x7D,0x07,0X7F,0x6 F};
void display_number(int32 j)
{
output_c(LED_MAP[j/600%10]) ;
output_low(PIN_A4);
delay_ms(2);
output_high(PIN_A4);
output_c(LED_MAP[j/20%10]) ;
output_low(PIN_A3);
delay_ms(2);
output_high(PIN_A3);
output_c(LED_MAP[j/10%6]) ;
output_low(PIN_A2);
delay_ms(2);
output_high(PIN_A2);
output_c(LED_MAP[j%10]);
output_low(PIN_A1);
delay_ms(2);
output_high(PIN_A1);
}
void main()
{
int32 m,count=0;
while(TRUE)
{
for (m=0;m<=10;m++)
display_number(count);
count=(count==720)? 0:count+1;
}
}
i want to have a program like this [1][2]:[0][0]...
THE ic that i used is 16f877a... |

When posting code please use the 'code' buttons to retain the layout of your code.
Quote: | THE ic that i used is 16f877a | You are using the wrong include file.
Code: | #byte port_d=8
#byte port_a=5
#byte port_c=8 | These lines are not used. Remove them.
Code: | byte CONST LED_MAP[10]={0x3F,0x06,0x5b,0x4F,0x66,0x6D,0x7D,0x07,0X7F,0x6 F}; | There is a space in between the last value '0x6_F'. Fix this.
Code: | output_high(PIN_A4); | Output A4 is Open Collector on most PIC processors. I don't know your circuit, but most likely you need a pull-up resistor or you will never output a high voltage.
Quote: | anybody can help me to fix this program,.. | It helps if you describe your problem. What do you see your program is doing and how is this different from what you want it to do?
Always post your compiler version number. |

Code: |
void main()
{
int32 m,count=0;
while(TRUE)
{
for (m=0;m<=0.01;m++)
display_number(count);
count=(count==86400)? 0:count+1;
output_d(0x02);
delay_ms(20);
output_d(0x04)
delay_ms(20);
output_d(0x08);
}
}
|
I have some problem on this part
Code: |
output_d(0x02);
delay_ms(20);
output_d(0x04)
delay_ms(20);
output_d(0x08);
|
Why when I add this, the 7segment will on off. It is possible to add this when the display_number run? What should I do?
My plan is when the 7segment run the LED pattern will also run. Please help me... |
