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;
     buffer[2]=value&0xff;
     buffer[3]=(value>>8)&0xff;
     buffer[4]=status;
     buffer[5]=checksum&0xff;
     buffer[6]=(checksum>>8)&0xff;
     buffer[7]=(checksum>>16)&0xff;
     buffer[8]=(checksum>>24)&0xff;
     buffer[9]=0x5A;
for(int i=0;i<10;i++){
    printf("%d ",buffer[i]);
}
    // Your logic to fill buffer
    // Then print buffer
}

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;
}
