Decode Status Register into Human-Readable Flags

Code

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

int bit_high(uint8_t byte, int pos) {
    return (byte & (1 << pos)) != 0;
}

void decode_status(uint8_t status_reg) {
    if(bit_high(status_reg, 0)) printf("Power On\n");
    if(bit_high(status_reg, 1)) printf("Error\n");
    if(bit_high(status_reg, 2)) printf("Tx Ready\n");
    if(bit_high(status_reg, 3)) printf("Rx Ready\n");
    if(bit_high(status_reg, 4)) printf("Overheat\n");
    if(bit_high(status_reg, 5)) printf("Undervoltage\n");
    if(bit_high(status_reg, 6)) printf("Timeout\n");
    if(bit_high(status_reg, 7)) printf("Reserved\n");
}

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