No output for Embedded application with PIC12, MPLAB and UART - c

Question

I am working on RGB LED project and that's controlled by a PIC12F1572. The software that I am using is MPLAB IDE with the HiTech C compiler. The plan is to use serial communication to send LED RGB combination data commands to the PIC to be stored in a variable that will make it perform the LED blink and glowing I have been able to establish UART communication.Every function or step I code is right by syntax and works on linux command line terminal if I compile..
And it fails if I try to simulate using register injection in MPLAB.I wanted to run it in simulation also (anyone knows how register injection actuallly works in MPLAB?)
The problem I face together when I try to debug . it compiles but doesn't work
here is my code :
Any idea or hint about the problem will be highly appreciated.
I personally fee that placing the code [hierarchical way] may be wrong
Thanks!

So till the receiving the UART frame and echoed back and from the storing data make LED blink , I am able to succeed and this is what I wanted for primary step here by hierarchical way
#include "mcc_generated_files/mcc.h"
#include <stdlib.h>
#include <stdio.h>
#include "atoh.h"
#include "LED.h"
#define _XTAL_FREQ 16000000
#define FRAMESIZE 19
void main(void)
{
uint8_t data,i,j,got_char;
uint8_t R_value, G_value ,B_value;
uint8_t value;
uint8_t RX_Buffer[FRAMESIZE];
uint8_t RGB_data[6] ,HEX_data[6];
// initialize the device
SYSTEM_Initialize();
INTERRUPT_GlobalInterruptEnable(); // Enable the Global Interrupts
INTERRUPT_PeripheralInterruptEnable(); // Enable the Peripheral Interrupts
while (1)
{
if (EUSART_DataReady)
{
for (i = 0; i<FRAMESIZE; i++)
{
RX_Buffer[i] = EUSART_Read();
if (RX_Buffer[i] == '\n')
break;
}
RX_Buffer[i] = '\n'; //append '\n' at the end of stoaring array for detection of frame
RX_Buffer[i+1] = '\0'; // End of an array
EUSART_WriteAnArrayOfBytes(RX_Buffer);
if(RX_Buffer[0]=='R' && RX_Buffer[FRAMESIZE-2] == '\n') //check for correct frame
{
LATAbits.LATA2 = 1;
__delay_ms(2000);
LATAbits.LATA2 = 0;
__delay_ms(1000);
}
}
}
