Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    for(int i = 0; i < 8;i++){
        if(status_reg & 1){
            switch(i){
                case 0:
                    printf("Power On\n");
                    break;
                case 1:
                    printf("Error\n");
                    break;
                case 2:
                    printf("Tx Ready\n");
                    break;
                case 3:
                    printf("Rx Ready\n");
                    break;
                case 4:
                    printf("Overheat\n");
                    break;
                case 5:
                    printf("Undervoltage\n");
                    break;
                case 6:
                    printf("Timeout\n");
                    break;
