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) {
    uint8_t final_data = data;
    if(ctrl -> parity_enable ){
        uint8_t parity = 0;
        for(int i=0;i<8;i++){
            parity ^= (data&0x01);
            data= data>>1;
        }
        if(ctrl -> parity_type ){
          final_data = (!parity<<7)|final_data;
        }
        else{
           final_data = (parity<<7)|final_data;
        }
    }
    return final_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;
}
