Serialized Data Buffer

Code

#include <stdio.h>
#include <stdint.h>
#include <string.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;
    // uint16_t* val_ptr = &value;
    // uint8_t * val_ptr_mine = (uint8_t *)val_ptr;
    memcpy(&buffer[2], &value, 2);
    buffer[4]=status;
    memcpy(&buffer[5],&checksum,4);
    buffer[9]=0x5A;
    // Your logic to fill buffer
    // Then print buffer
    for(int i=0;i<10;i++) {
        printf("%d ", buffer[i]);
    }
}

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;
}
