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
    uint8_t frame =0;
    uint8_t sum_ones=0;
    uint8_t bit_parity=0;

    if(ctrl->parity_enable == 0){
     return data;
     }else{
        

        for(int i=0;i<7;i++){
            if((data>>i) & 1){
                sum_ones+=1;
            }
        }
        if(ctrl-> parity_type == 0){
            bit_parity=(sum_ones & 1U);
        }else{
             bit_parity = (!(sum_ones & 1U));
        }

        frame= data| (bit_parity << 7);
        return frame;
     }
   

    return frame;
}

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;
}
