@combaindeft Yes, but only for telling the frequency, and not setting it. If you look at the esp32 port of micropython.org, you can use that method for setting the frequecy, or at least it is intended to do so. It accepts an argument, but does not call the idf function. Code below:
STATIC mp_obj_t machine_freq(size_t n_args, const mp_obj_t *args) {
if (n_args == 0) {
// get
return mp_obj_new_int(ets_get_cpu_frequency() * 1000000);
} else {
// set
mp_int_t freq = mp_obj_get_int(args[0]) / 1000000;
if (freq != 80 && freq != 160 && freq != 240) {
mp_raise_ValueError("frequency can only be either 80Mhz, 160MHz or 240MHz");
}
/*
system_update_cpu_freq(freq);
*/
return mp_const_none;
}
}
STATIC MP_DEFINE_CONST_FUN_OBJ_VAR_BETWEEN(machine_freq_obj, 0, 1, machine_freq);
Edit: This code does not work.
