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 cnt=0;
    for(int i=0;i<7;i++){
        if((data & (1<<i))){
            cnt++;
        }
    }

    if((ctrl->parity_enable==1 && ctrl->parity_type==0) ){
        
        if(cnt%2==0){
            data= data;
        }
        else{data= data | (1<<7);}
    }else if(ctrl->parity_enable==1 && ctrl->parity_type==1){
        if(cnt%2==0){
            data= data | (1<<7);
        }
        else{
            data=data;
            }
    }
    
    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;
}
