Pic16c745 help??

[cuitesun]

Hi everyone is my first time here i really really need help ,i am stuck in the code c+ to light up a Led using PIC16C745, 6mhz oscillator. I don't understand why doesn't it light up ): tell me if there is a mistake thanks.

below is my code:

#include <htc.h>
//#include "delay.h"
__CONFIG(WDTDIS & PWRTDIS & UNPROTECT & H4);


void init(void)
{
PORTB = 0x02;
TRISB = 0x02;
}
void InitUSART(void)
{
TXSTA = 0x22;
RCSTA = 0x90;
SPBRG = 0x9b;
}

void enter(void)
{
while(!TRMT);
TXREG = 0x0d;
}

void tx_start(void)
{
while(!TRMT);
TXREG = 0x1a;
}

void send_msg(const char *str)
{
char ps;
ps = *str;
while(ps>0)
{
str++;
if (ps== 0) break;
while(!TRMT);
TXREG = ps ;
ps = *str;
}

}


void main(void)
{
init();
InitUSART();

while (1)
{

if(RB1 == 0)
{
RB2 = 0x1;
RB3 = 0x04;

send_msg("at+cmgf=1");
enter();
DelayMs(50);
send_msg("at+cmgs=");
send_msg("+6582543453");
enter();
DelayMs(50);
send_msg("hello");
tx_start();
DelayMs(5000);

RB2 = 0x0;

}
else if(RB1=1)
{
RB2 = 0x0;
RB3 = 0x0;
}
}
}

Everything to this point looks ok. See below for what needs some attention.

void main(void)
{
init();
InitUSART();

while (1)
{

if(RB1 == 0)                           //Is this a switch? There's no debounce routine.
{
RB2 = 0x1;                              //Invalid value for a single bit, can be 0x00 or 0x01 only
RB3 = 0x04;                            //Same issue here.

send_msg("at+cmgf=1");
enter();
DelayMs(50);
send_msg("at+cmgs=");
send_msg("+6582543453");
enter();
DelayMs(50);
send_msg("hello");
tx_start();
DelayMs(5000);

RB2 = 0x0;                                              

}
else if(RB1=1)                      //Here you're assigning a value to RB1, you need to use
{                                            //else if(RB1==1)
RB2 = 0x0;
RB3 = 0x0;
}
}
}

I hope you have an emulator or flashable version of the chip, testing on a OTP chip could get costly.

Hi LTX71CM tks for your response .I will look into it and try it out.But mine is using MPLAB software and PICSTART plus to burn my code into the microchip .
