What are the disadvantages of ESP_32 controllers? I often met such a question "What to start learning STM or AVR?". But I haven’t seen anywhere that someone wanted to study esphi, although the controller seems to be powerful, they even make some kind of PLC based on it.
I decide to start studying MK, like these are your calls to registers and all that. Along the way, do DIY, and make some smart devices.

The main problem with ESP systems is that you don't have full control over them. You can only write CALLBACK-reactions to all kinds of events, but part of the time the processor will be busy executing a part of the firmware that is closed from you, which you cannot influence.
Because of this, any hard realtime that is easily done on AVR or STM (like frequency converters) cannot be done on ESP without completely disabling WiFI.
