Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {

    const char* bit_meaning[8] = { //look up array
        "Power On", 
        "Error", 
        "Tx Ready", 
        "Rx Ready", 
        "Overheat", 
        "Undervoltage", 
        "Timeout", 
        "Reserved"
        };

    for(int i = 0; i < 8; i++){
        if(status_reg & (1u << i)){
            printf("%s\n", bit_meaning[i]);
        }
    }
}

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