Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    const char *s[]={"Power On","Error","Tx Ready","Rx Ready","Overheat","Undervoltage","Timeout","Reserved"};
    int cnt=-1;
    while(status_reg){
        cnt+=1;
        if(status_reg & 1){
            printf("%s\n",s[cnt]);
        }
        status_reg=status_reg>>1;
        // printf("%b",status_reg);
        
    }
}

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