Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {

    const char *flags[8] = {
        "Power On",      // Bit 0
        "Error",         // Bit 1
        "Tx Ready",      // Bit 2
        "Rx Ready",      // Bit 3
        "Overheat",      // Bit 4
        "Undervoltage",  // Bit 5
        "Timeout",       // Bit 6
        "Reserved"       // Bit 7
    };

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

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