Construct UART Data Frame with Parity Bit

Code

#include <stdio.h>
#include <stdint.h>

typedef struct {
    uint8_t parity_enable : 1;
    uint8_t parity_type   : 1;
    uint8_t reserved      : 6;
} UART_Control;

uint8_t create_uart_frame(uint8_t data, UART_Control *ctrl) {
    // Your logic here
    int count =0;
    if(ctrl->parity_enable == 0) return data;

    else{
        for(int i=0; i<7; i++){

            if(((data>>i)&0x01)==1) count++;
        }
    }
    if(ctrl-> parity_type == 0){

        if(count%2==0) data = data|0x00;

        else{ data = data|0x80; }
    }   else {

        if(count%2==0)  data = data|0x80;

        else{ data = data|0x00;  }

    }


    return data;
}

int main() {
    uint8_t data;
    scanf("%hhu", &data);  // 7-bit input

    uint8_t parity_enable, parity_type;
    scanf("%hhu %hhu", &parity_enable, &parity_type);

    UART_Control ctrl;
    ctrl.parity_enable = parity_enable;
    ctrl.parity_type = parity_type;

    uint8_t frame = create_uart_frame(data, &ctrl);
    printf("frame = 0x%02X", frame);

    return 0;
}
