ESP-IDF equivalent of Arduino millis()

In Arduino, the millis() function returns the number of milliseconds since the program started. In ESP-IDF, you can achieve the same functionality using the esp_timer_get_time() function, which returns the time in microseconds. To convert it to milliseconds, you need to divide by 1000.

#include <esp_timer.h>

uint32_t millis() {
    return esp_timer_get_time() / 1000;
}

// Usage example
void myFunc() {
    uint32_t currentMillis = millis();
    // Use currentMillis as needed
}
