Decode Status Register into Human-Readable Flags

Code

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


void decode_status(uint8_t status_reg) {

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