Decode Status Register into Human-Readable Flags

Code

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

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

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