Decode Status Register into Human-Readable Flags

Code

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

int get_bit(int val, int pos){
    
    return ((val ) & (1U << pos));

}

void decode_status(uint8_t status_reg) {
    int reg_length = 8;
    int i = 0;
    while(i<reg_length){
        switch(get_bit(status_reg,i)){
        case 1:
            printf("Power On\n");
            break;
        case 2:
            printf("Error\n");
            break;
        case 4:
            printf("Tx Ready\n");
            break;
        case 8:
            printf("Rx Ready\n");
            break;
        case 16:
            printf("Overheat\n");
            break;
        case 32:
            printf("Undervoltage\n");
            break;
        case 64:
            printf("Timeout\n");
            break;
        case 128:
            printf("Reserved\n");
            break;
        }
        i++;
    }
}

int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
