Decode Status Register into Human-Readable Flags

Code

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

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

void decode_status(uint8_t status_reg) {
//    char flag_names[][20]={"Power On", "Error", "Tx Ready", "Rx Ready", "Overheat", "Undervoltage", "Timeout", "Reserved"};
   for(int i = 0; i<8; i++){
    if(status_reg & (1<<i)) {
        printf("%s\n",flag_names[i]);
        }
   }
}

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