Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // check each reg bit individually, then set a corresponding variable to output if something is on. 
    int set_indicator[8] = {0, 0, 0, 0, 0, 0, 0, 0 };
    char *flags[] = {"Power On", "Error", "Tx Ready", "Rx Ready", "Overheat", "Undervoltage", "Timeout", "Reserved"};
    
    //Check if a particular bit is set
    for(int i = 0; i <= 7; i++){
        if(status_reg & 1 << i){
            set_indicator[i] = 1;
            printf("%s\n", flags[i]); 
            
        }
    }

}

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