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) {
    Packet* p1=(Packet* )buffer;
    printf("Start: %d\n",p1->start);
    printf("Command: %d\n",p1->command);
    printf("Data: %d\n",p1->data);
    printf("CRC: %d\n",p1->crc);
    printf("End: %d\n",p1->end);
    /*
    printf("Start: %d\n",*(buffer));
    printf("Command: %d\n",*(buffer+1));
    printf("Data: %d\n",(*(buffer+3)<<8)|*(buffer+2));
    printf("CRC: %d\n",*(buffer+4));
    printf("End: %d\n",*(buffer+5));
    */
    // Overlay struct and print values
}

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