Decode Status Register into Human-Readable Flags

Code

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

const char *name[8] = {
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved",
};

void decode_status(uint8_t status_reg) {
    int i = 0;
    while (status_reg) {
        if (status_reg & 0x1)
            printf("%s\n", name[i]);
        status_reg >>= 1;
        i++;
    }
}

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