[SOLVED] Receiving data to PIC controller from terminal

[jai patel]

Hello

I am try to receiving sequence of fixed length by below function. so, can anyone say that what I have to pass in below function at the place of Output.

/******************************************************************************/
/* Read data from UART                                                       */
/*****************************************************************************/
char UART_Read() {

    while (!RCIF);
    return RCREG;
}

void UART_Read_Text(char *Output, unsigned int length) {
    int i;
    for (int i = 0; i < length; i++)
        Output[i] = UART_Read();
}

I am using PIC16F887 and hi tech c compiler with MPLAB X IDE.

you need to initialize a pointer variable or an array outside the function UART_read_Text() and than pass it to your function.

after the function is executed your pointer will point to data that is received by function.

ok I have initialised it but what should I have to pass at the place of *output in function.

 

[ec_nisarg]

char *rcvdstr;
UART_Read_Text(rcvdstr, 10);

or

char rcvdstr[10];
UART_Read_Text(rcvdstr, 10);

hello


you don't need to pass anything to the function.just calling that function without any arguments,

define the length of the string in outside the main fun...

Also you need to initialize ur char pointer with some string so that it initializes some memory nd no other variable takes in a memory in between it..
