PIC16F628A to Arduino RF Communication Fails (433MHz) - arduino

Question

I have pic16f628a and Arduino UNO...
I use MikroC for PIC...
I use 433 mhz transmitter and receiver.
My purpose is reading datas from Arduino UNO which I send from PIC16F628A; but I couldn't success it...
The circuit of PIC16F628A (Transmitter):
The circuit of Transmitter
I connected first pin of receiver to +5V of Arduino;
second pin of receiver to 12.pin of Arduino,
last pin of receiver to GND pin of Arduino.
Transmitter(PIC16F628A):
char pre[15]={'U','U','U','U','U',255,255,255,255,255,0,0,0,0,0}; //start bytes...
char ileri[3]={'f','r','w'};
char geri[3]={'b','c','k'};
char dur[3]={'d', 'u', 'r'};
char i=0,j=0;
void kurulum()
{
CMCON= 7;
TRISB= 2;
UART1_Init(2400);
delay_ms(100);
}
void main()
{
kurulum();
while(1)
{
for(i=0;i<15;i++)
{
UART1_Write(pre[i]);
}
for(j=0;j<10;j++)
{
for(i=0;i<3;i++)
{
while(!UART1_Tx_Idle());
UART1_Write(ileri[i]);
}
}
//*************************************************************
for(i=0;i<15;i++)
{
UART1_Write(pre[i]);
}
for(j=0;j<10;j++)
{
for(i=0;i<3;i++)
{
while(!UART1_Tx_Idle());
UART1_Write(geri[i]);
}
}
for(i=0;i<15;i++)
{
UART1_Write(pre[i]);
}
for(j=0;j<10;j++)
{
for(i=0;i<3;i++)
{
while(!UART1_Tx_Idle());
UART1_Write(dur[i]);
}
}
}
}
Receiver (Arduino):
// receiver.pde
//
// Simple example of how to use VirtualWire to receive messages
// Implements a simplex (one-way) receiver with an Rx-B1 module
//
// See VirtualWire.h for detailed API docs

#include <VirtualWire.h>
const int led_pin = 13;
const int receive_pin = 12;
void setup()
{
delay(1000);
Serial.begin(9600); // Debugging only
Serial.println("setup");
// Initialise the IO and ISR
vw_set_rx_pin(receive_pin);
//vw_set_ptt_inverted(true); // Required for DR3100
vw_setup(2400); // Bits per sec
vw_rx_start(); // Start the receiver PLL running
pinMode(led_pin, OUTPUT);
}
void loop()
{
uint8_t buf[VW_MAX_MESSAGE_LEN];
uint8_t buflen = VW_MAX_MESSAGE_LEN;
if (vw_get_message(buf, &buflen)) // Non-blocking
{
int i;
digitalWrite(led_pin, HIGH); // Flash a light to show received good message
// Message with a good checksum received, dump it.
Serial.print("Got: ");
for (i = 0; i < buflen; i++)
{
Serial.print(buf[i], HEX);
Serial.print(' ');
}
Serial.println();
digitalWrite(led_pin, LOW);
}
}
I tried this code; but it didn't work...
There is another code;
void setup() {
Serial.begin(2400);
}
void loop() {
if (Serial.available() > 0){
Serial.println(Serial.read());
}
}
Before trying it; I connected data pin of receiver to RX pin of Arduino...
I usually got '0' byte.i
It didn't work as I desired...

Answer 1

SOLVED
The tests I have done so far were already taking the true datas but I was viewing them as numbers...
That's why I couldn't understand that It was working well.
Let's have a look at codes;
Transmitter:
The same as transmitter code at question message
Arduino (Receiver):
char x, msg[6];
int i= 0;
void setup() {
Serial.begin(2400);
}
void loop() {
if (Serial.available() > 0){
msg[i] = Serial.read();
if (msg[0]=='f' || msg[0] == 'b' || msg[0] == 'd'){
i++;
}
if (i==3){
Serial.println(msg);
i = 0;
msg[0]=0;
}
}
}
msg[0]=='f' || msg[0] == 'b' || msg[0] == 'd'
The purpose of comparison above is catching "frw", "bck" or "dur" messages which I sent transmitter...
The data pin of the receiver should be connected RX pin of the Arduino...
