Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    struct flag{
        int key;
        char value[15];
    };
    struct flag data[]={
        {0,"Power On"},
        {1,"Error"},
        {2,"Tx Ready"},
        {3,"Rx Ready"},
        {4,"Overheat"},
        {5,"Undervoltage"},
        {6,"Timeout"},
        {7,"Reserved"}
    };

    for(int i=0;i<=7;i++){
        if(status_reg & (1<<i)){
            printf("%s\n",data[i].value);
        }
    }


}

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