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 pack;
    pack.start = *buffer;
    pack.command = *(buffer+1);
    pack.data = *(buffer+2);
    pack.data = pack.data + (*(buffer+3)<<8);
    pack.crc = *(buffer+4);
    pack.end = *(buffer+5);
    printf("Start: %d\nCommand: %d\nData: %d\nCRC: %d\nEnd: %d", pack.start, pack.command, pack.data, pack.crc, pack.end);
}

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