Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    for (int bit = 0; bit < 8; bit++) {

        if (status_reg & (1 << bit)) {

            if (bit == 0) printf("Power On\n");
            else if (bit == 1) printf("Error\n");
            else if (bit == 2) printf("Tx Ready\n");
            else if (bit == 3) printf("Rx Ready\n");
            else if (bit == 4) printf("Overheat\n");
            else if (bit == 5) printf("Undervoltage\n");
            else if (bit == 6) printf("Timeout\n");
            else if (bit == 7) printf("Reserved\n");
        }
    }
}

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