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
     uint8_t  start   = buffer[0];
     uint8_t  command = buffer[1];
     uint16_t  data  = buffer[2] | (buffer[3] << 8);
     uint8_t  crc  = buffer[4];
     uint8_t  end  = buffer[5];
      printf("Start: %u\n", start);
      printf("Command: %u\n", command);
      printf("Data: %u\n", data);
      printf("CRC: %u\n", crc);
      printf("End: %u\n", end);
}

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