Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t reg) {
    if((reg & 1) !=0) printf("Power On\n");
    if((reg&(1<<1)) != 0 ) printf("Error\n");
    if((reg&(1<<2)) != 0 ) printf("Tx Ready\n");
    if((reg&(1<<3)) != 0 ) printf("Rx Ready\n");
    if((reg&(1<<4)) != 0 ) printf("Overheat\n");
    if((reg&(1<<5)) != 0 ) printf("Undervoltage\n");
    if((reg&(1<<6)) != 0 ) printf("Timeout\n");
    if((reg&(1<<7)) != 0 ) printf("Reserved");
}

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