Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg)
{
    char val[8][15] = {"Power On", "Error", "Tx Ready", "Rx Ready", "Overheat", "Undervoltage", "Timeout", "Reserved"};
    int i = 0;

    while (status_reg > 0)
    {
        if ((status_reg & 1) == 1)
            printf("%s\n", val[i]);

        status_reg >>= 1;
        i++;
    }
}

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