Decode Status Register into Human-Readable Flags

Code

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


#define power (1<< 0)
#define error (1<< 1)
#define tx (1<< 2)
#define rx (1<< 3)
#define overheat (1<< 4)
#define undervolt (1<< 5)
#define timeout (1<< 6)
#define reserve (1<< 7)

void decode_status(uint8_t status_reg) {
    // Your logic here
    if (status_reg & power) printf ("Power On\n");
    if (status_reg & error) printf ("Error\n");
    if (status_reg & tx) printf ("Tx Ready\n");
    if (status_reg & rx) printf ("Rx Ready\n");
    if (status_reg & overheat) printf ("Overheat\n");
    if (status_reg & undervolt) printf ("Undervoltage\n");
    if (status_reg & timeout) printf ("Timeout\n");
    if (status_reg & reserve) printf ("Reserved\n");
}

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