| How do I transmit data with the rf12f675 RFPIC |

Hi all
I'm trying to develop an application to send data from a transmitter to a receiver with RF. The problem are when I try to send RF data from the transmitter. I don't know if the rf12f675 is sending the data or not, because I don't know if the sequence of instructions its correctly formed.
The code is as follow.
| Code: |
#include <12F675F.h>
#device ADC=10
#fuses INTRC_IO,NOWDT,NOPUT,NOPROTECT,NOCPD,NOMCLR
#use delay(clock=4000000)
#define GP0 PIN_A0
#define GP1 PIN_A1
#define GP2 PIN_A2
#define GP3 PIN_A3
#define GP4 PIN_A4
#define GP5 PIN_A5
//#byte OSCCAL = 0x90
#int_AD
AD_isr()
{
SETUP_ADC(ADC_OFF);
}
void init()
{
//OSCCAL = 0x80; // set internal oscillator to mid frequency
// enable_interrupts(GLOBAL);
// enable_interrupts(INT_AD);
set_tris_a(0b00111011);
setup_comparator( NC_NC_NC_NC );
setup_adc_ports( sAN0|sAN1|VSS_VDD );
setup_adc( ADC_CLOCK_INTERNAL );
}
main()
{
int codigo;
int value;
init();
codigo=15500;
while ( TRUE ) // blink LED
{
set_adc_channel(1);
delay_us(22);
value = read_adc();
output_high ( GP5 );
delay_ms (5);
output_a( codigo );
output_a( value );
output_low( GP5 );
setup_adc( ADC_OFF );
delay_ms( 1000 );
}
} |
The GP2 is the port connected to the DATAAsk.
The GP5 pin is connected to the RFEN to enable the oscillator to modulate the data.
All the elements are from the PICKIT Flash starter kit form microchip.
I use the transmit board came with this Kit.
sorry for my bad english
thanks |

| Ayuda con RFPIC12F675 |

I am new to the forum and I want to know if any of you has established communication with RFPIC's. I'm in a project at the university and have not established communication between the TX and RX. I have the source code but the problem is that it's in assembly and I really do not understand this type of programming.
If anyone of you could guide me, or if anyone of you has any example of this I would appreciate it.

hola soy nuevo en el foro y pues kisiera saber si alguie de ustedes ya establecio comunicacion con RFPIC's, ya que me encuentro en un proyecto de la universidad y no puesdo establecer comunicacion entre el TX y RX, tengo los codigos fuente pero el problema es que estan en ensamblador y la verdad no entiendo ese tipo de programacion.
si alguien de ustedes me pudiera orientar o si alguien de ustedes tiene algun ejemplo de ello se lo agradeceria muxo |
