Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    int bit_status;
    const char *status_flag[] = {"Power On", "Error", "Tx Ready", "Rx Ready", "Overheat", "Undervoltage", "Timeout", "Reserved"};
    for(int i=0; i<8; i++) {
        bit_status = (status_reg >> i) & 1;
        if(bit_status==1) {
            printf("%s\n", status_flag[i]);
            

        }
  
        
    }
}

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