Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    for( int i = 0 ; i<8;i++){
        if((status_reg&(1<<i))==1) printf("Power On\n");
        else if((status_reg&(1<<i))==2) printf("Error\n");
        else if((status_reg&(1<<i))==4) printf("Tx Ready\n");
        else if((status_reg&(1<<i))==8) printf("Rx Ready\n");
        else if((status_reg&(1<<i))==16) printf("Overheat\n");
        else if((status_reg&(1<<i))==32) printf("Undervoltage\n");
        else if((status_reg&(1<<i))==64) printf("Timeout\n");
        else if((status_reg&(1<<i))==128) printf("Reserved\n");
    }
}

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