Extract Packet Fields from Byte Stream

Code

#include <stdio.h>
#include <stdint.h>

typedef struct {
    uint8_t start;
    uint8_t command;
    uint16_t data;
    uint8_t crc;
    uint8_t end;
} Packet;

void print_packet_fields(uint8_t *buffer) {
    printf("Start: %u\n", ((Packet*)(buffer))->start);
    printf("Command: %u\n", ((Packet*)(buffer))->command);
    printf("Data: %u\n", ((Packet*)(buffer))->data);
    printf("CRC: %u\n", ((Packet*)(buffer))->crc);
    printf("End: %u", ((Packet*)(buffer))->end);
}

int main() {
    uint8_t buffer[6];
    for (int i = 0; i < 6; i++) {
        scanf("%hhu", &buffer[i]);
    }
    print_packet_fields(buffer);
    return 0;
}
