Decode Status Register into Human-Readable Flags

Code

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

// Array to map bits to flag meanings
const char* flag_names[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
};
void decode_status(uint8_t status_reg) {

    for(uint8_t i = 0 ;i<8;i++)
    {
        //check for set bits and print according to
       if(status_reg & (1<<i))
       {
         printf("%s\n",flag_names[i]);
       }


    }
}

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