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];
    uint8_t index=0;
    buffer[index]=0xA5;
    index++;
    buffer[index]=command;
    index++;
    uint8_t right_shift=0;
    for(uint8_t i=0;i<2;i++)
    {
        buffer[index]=((value>>right_shift) & (0xff));
        index++;
        right_shift+=8;
    }
    buffer[index]=status;
    index++;
    right_shift=0;
    for(uint8_t i=0;i<4;i++)
    {
        buffer[index]=((checksum>>right_shift) & (0xff));
        index++;
        right_shift+=8;
    }
    buffer[index]=0x5A;

    for(uint8_t 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;
}
