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
    if(ctrl->parity_enable){
        uint8_t count = 0, i = 0;
        while(i != 7){
            count += ((data >> i) & (1));
            i++;
        }
        if(ctrl->parity_type){
            data = (count % 2 != 0) ? (data & (~(1 << 7))) : (data | (1 << 7));
        }
        else{
            data = (count % 2 == 0) ? (data & (~(1 << 7))) : (data | (1 << 7));
        }
    }
    else{
        data = data & (~(1 << 7));
    }
    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;
}
