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) {
    // Overlay struct and print values
    Packet str;

    str.start   = buffer[0];
    str.command = buffer[1];
    str.data    = (uint16_t)buffer[2] | ((uint16_t)buffer[3] << 8);
    str.crc     = buffer[4];
    str.end     = buffer[5];


    printf("Start: %d",str.start);
    printf("\nCommand: %d",str.command);
    printf("\nData: %d",str.data);
    printf("\nCRC: %d",str.crc);
    printf("\nEnd: %d",str.end);
}

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