Decode Status Register into Human-Readable Flags

Code

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

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

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