Decode Status Register into Human-Readable Flags

Code

#include <stdio.h>
#include <stdint.h>

const char *levelname[] = {
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved"

};

void decode_status(uint8_t status_reg) {
    // Your logic here
    uint8_t extracted;
    for(int i=0;i<8;i++){
        extracted = status_reg >> i & 1;
        if(extracted == 1){
            printf("%s\n",levelname[i]);

        }

    }
}

int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    decode_status(reg);
    return 0;
}
