Serialized Data Buffer

Code

#include <stdio.h>
#include <stdint.h>

void build_packet(uint8_t command, uint16_t value, uint8_t status, uint32_t checksum) {
    printf("%d %d %d %d %d %d %d %d %d %d",
    0xa5,command,value&0xff,value>>8&0xff,status,checksum&0xff,checksum>>8&0xff,checksum>>16&0xff,checksum>>24&0xff,0x5a);
}

int main() {
    uint8_t cmd, status;
    uint16_t val;
    uint32_t crc;

    scanf("%hhu %hu %hhu %u", &cmd, &val, &status, &crc);
    build_packet(cmd, val, status, crc);
    return 0;
}
