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) {
    
    int count = 0;
    if (ctrl-> parity_enable ==0){
        return (0b0111111)&data;
    }
    else {
        for (int i = 0; i < 7; i++){
            if((data & (1 << i)) != 0){
                count = count+1;
            }
            else {
                count = count;
            }
        }
    //    return count;
        if (ctrl -> parity_type == 0){
            return (count % 2 == 0)? (0b01111111&data):data|0b10000000;
        }
        else {
            return (count % 2 == 0)? (data|0b10000000):(0b01111111&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;
