Decode Status Register into Human-Readable Flags

Code

#include <stdio.h>

#include <stdint.h>

const char *flag_names[8] = {

    "Power On",

    "Error",

    "Tx Ready",

    "Rx Ready",

    "Overheat",

    "Undervoltage",

    "Timeout",

    "Reserved"

};

void decode_status(uint8_t status_reg) {

    for (int i = 0; i < 8; i++) {

        if ((status_reg >> i) & 1) {

            printf("%s\n", flag_names[i]);

        }

    }

}

int main() {

    uint8_t reg;

    scanf("%hhu", &reg);

    decode_status(reg);

    return 0;

}
