Decode Status Register into Human-Readable Flags

Code

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

// Status codes
typedef enum {
    STATUS_POWER_ON = 0,
    STATUS_ERROR,
    STATUS_TX_READY,
    STATUS_RX_READY,
    STATUS_OVERHEAT,
    STATUS_UNDERVOLTAGE,
    STATUS_TIMEOUT,
    STATUS_RESERVED,
    STATUS_MAX
} StatusCode;

// Lookup table
static const char* statusText[STATUS_MAX] = {
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved"
};


void decode_status(uint8_t status_reg) {
    // Your logic here
    // To check bit 0 → reg & (1 << 0)

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

}

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