EUSART1_Read() function to receive string

[engr_joni_ee]

I am using PIC18F. I am wondering if anyone has tried to get string using this function which is generated in the MCC in MPLAB.

uint8_t EUSART1_Read(void)
{
    while(!PIR1bits.RC1IF)
    {
    }

    eusart1RxLastError.status = 0;
  
    if(1 == RCSTA1bits.OERR)
    {
        // EUSART1 error - restart

        RCSTA1bits.CREN = 0;
        RCSTA1bits.CREN = 1;
    }

    return RCREG1;
}

I have made the following function outside the main() that calls the MCC generated function "EUSART1_Read()". I need to get a string basically through the following function but this has some issues that involves return types and assignments. Can someone please have a look and help me to resolve the issue in receiving the string using the MCC generated function.

char EUSART_Read(void)
{
int i = 0;

char rx = 'a';
char rx_string[10];

while (rx != 0x0d)
{
rx = EUSART1_Read(); // Return type of this function is uint8_t
rx_string[i] = rx; // store the data in string
i++;
}
return rx_string;
}

I need to call this function in the main() function but it says that rx_string is not assignable.

 rx_string = EUSART_Read();

Even if I define rx_string as uint8_t, the problem is the same. Somewhere I am not using the correct data type and return type.

Hi,

I´m no C specialist, but if I´m not mistaken you can´t return strings.
Try to define the string outside and pass it as pointer.
