Decode Status Register into Human-Readable Flags

Code

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

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


void decode_status(uint8_t status_reg) {
    int n = 0;
    for (int i = 0; i < 8; i++)
    {
        if (status_reg & (1 << i)) printf("%s\n", messaggi[i]);

    }
}

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