| LED flashing problem |

Hi there
I am new to using the CCS compiler. I was trying to flash an LED just as a test program but the LED doesnt flash. My code is as below:
| Code: |
#include "C:\Documents and Settings\Atmadarshini dd\My Documents\trial.h"
#include <stdio.h>
#include <stddef.h>
#include <stdlib.h>
#include <string.h>
#int_RDA
#define MCLR PIN_B1
#define DATA_OUT PIN_B2
#define DATA_IN PIN_B4
#define CLOCK PIN_B5
RDA_isr() {
}
void main() {
setup_adc_ports(NO_ANALOGS);
setup_adc(ADC_CLOCK_DIV_2);
setup_spi(FALSE);
setup_counters(RTCC_INTERNAL,RTCC_DIV_2);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
enable_interrupts(INT_RDA);
enable_interrupts(global);
for(;;)
{
output_low(CLOCK);
delay_ms(200);
output_high(CLOCK);
delay_ms(200);
}
}
|
could someone tell me what i am doing wrong asap.
Thanks |

Try it with the changes above. |

You forgot to add | Code: | | #use delay(clock=....) |

| Code: |
#include <16F877.h> // Change according with your uC
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000) // change according with the Xtal you are using
void main()
{
while(1)
{
output_toggle(PIN_B5);
delay_ms(200);
}
}

Hi i tried it...It didnt work
I have a 1K resistor that is connected to pin RB5 and the resistor goes to LED and the LED is connected to 5V(the postive side of the LED).
The same circuit works when use the cc5x compiler.
void main() {
setup_adc_ports(NO_ANALOGS);
setup_adc(ADC_CLOCK_DIV_2);
setup_spi(FALSE);
setup_counters(RTCC_INTERNAL,RTCC_DIV_2);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
// since you're not using the RDA interrupt, DON'T enable it unless you
// have a proper handler for it!!!
//enable_interrupts(INT_RDA);
//enable_interrupts(global);
//for(;;) I'm going to replace this for loop with something more "standard"
while (TRUE)
{
output_low(CLOCK);
delay_ms(200);
output_high(CLOCK);
delay_ms(200);
}
}
[/code]

hi this is added in the .h file. so i presume that it gets added to the project. |

hi
it says undefined output_toggle when i se your code above |

Output_toggle can be replaced by:
| Code: |
while(1)
{
output_high(CLOCK);
delay_ms(200);
output_low(CLOCK);
delay_ms(200);
}
|
You would know that in your inquire you must include:
1) Compiler version. (3.xxx format)
2) Full header.
3) Short and concise hardware description.
Keep well,
