Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    int i;
    for(i=0;i<8;i++){
        if(status_reg>>i&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;

int main() {
