Decode Status Register into Human-Readable Flags

Code

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

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

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