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 pkt;

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


    printf("Start: %d\n",pkt.start);
    printf("Command: %d\n",pkt.command);
    printf("Data: %d\n",pkt.data);
    printf("CRC: %d\n",pkt.crc);
    printf("End: %d\n",pkt.end);


}

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