Hi

I have written the code for serially send data transmission between PC-hyper-terminal and PIC16F877A. When I am using MP LAB IDE Hitech C compiler its showing the error like pointer is required and any of you please check the code and register description is correct or not

What I have tried:

  #include<pic.h>
  #include<string.h>


void pic_init(void)
{
	TRISC7=1;
	TRISC6=0;
}

void uart_init(void)
{
	TXSTA=0x20;
	RCSTA=0x90;
	SPBRG=15;
}

void tx(unsigned char byte)
{
int i;
TXREG=byte;
while(!TXIF);
for(i=0;i<400;i++);
}

void string_uart(char *q)
{
	while(*q)
	{
	*(*q++);
}
}
unsigned char rx()
{
	while(!RCIF);
	return RCREG;
}



void main()
{

	//char *q;
	pic_init();
	uart_init();
	tx('N');
	rx();
	string_uart("test program");
}
