// ... some code here?

It seems that the question is incomplete and only contains the comment "// ... some code here?". To provide a helpful answer, additional information about the context or the task related to embedded/IoT code is needed.

If you need an example of embedded system code, here is a simple example of blinking an LED in C for a microcontroller:

#include <avr/io.h>
#include <util/delay.h>

int main(void) {
    DDRB |= (1 << PB0); // Set pin PB0 as output

    while (1) {
        PORTB ^= (1 << PB0); // Toggle pin state
        _delay_ms(500);      // Delay 500 ms
    }

    return 0;
}
