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;
    printf("%hhu %hhu %hhu %hhu %hhu %hhu %hhu %hhu %hhu %hhu", buffer[0],buffer[1], buffer[2], buffer[3], buffer[4], buffer[5], buffer[6], buffer[7], buffer[8], buffer[9]);

    // 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;
}
