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) {
    uint8_t buffer[10];

   buffer[0]=0xA5;
   buffer[1]=command&0xFF;
   buffer[2]=value&0xFF;
   buffer[3]=(value>>8)&0xFF;
   buffer[4]=status&0xFF;
   buffer[5]=checksum&0xFF;
   buffer[6]=(checksum>>8)&0xFF;
   buffer[7]=(checksum>>16)&0xFF;
    buffer[8]=(checksum>>24)&0xFF;
    //buffer[9]=(checksum>>32)&0xFF;
    buffer[9]=0x5A;
    for (int i;i<10;i++)
    {
        printf("%d", buffer[i]);
        printf(" ");
    }

}

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;
}
