Decode Status Register into Human-Readable Flags

Code

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

const char* MappingTableToPrint[] = {
    "Power On\n",
    "Error\n",
    "Tx Ready\n",
    "Rx Ready\n",
    "Overheat\n",
    "Undervoltage\n",
    "Timeout\n",
    "Reserved\n"};

void decode_status(uint8_t status_reg) {
    uint16_t len = sizeof(&MappingTableToPrint);
    for(int i = 0; i < len; i++)
    {
        if ( status_reg & ( 1 << i )) printf(MappingTableToPrint[i]);
    }
}

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