Hello!

I did not find anywhere characteristics of ADC reference voltage.
There are only that it is about 1100 mV.
During calibration i can compensate initial VREF error.
But i need to know more info about VREF, such as
- Output Voltage Drift (depends on temperature), ppm/°C
- Long-Term Output ...

Hello!

I need to use hardware timers of ESP32 simultaneously with esp_timer.

Is it correct, that esp_timer always uses first timer of timer group defined by LACT_MODULE (i.e. LACT_MODULE=0 - first timer of group 0, LACT_MODULE=1 - first timer of group 1)?

As for GPTimer - i found, that this ...

Hello!

I dont clearly understand about thread safety of netif and lwip:

ESP32 documentations says:
ESP-NETIF.
The APIs it provides are thread safe, even if the underlying TCP/IP stack APIs are not.


So, i cant understand thead safety implimentation when using configuration LWIP_TCPIP_CORE ...
