[TERMINAL WIDGET ESP32 EXAMPLE] =====================================================================================
3+
4+
Environment prepare:
5+
In your Blynk App project:
6+
- add "Terminal" widget,
7+
- bind it to Virtual Pin V2,
8+
- add input line option in widget settings
9+
- Run the App (green triangle in the upper right corner).
10+
- define your auth token for current example
11+
- define SSID and WiFi password that will be used by ESP32 board
12+
- run current example
13+
14+
15+
This started program will call and execute event handler "write_virtual_pin_handler" if new
16+
event comes from terminal app widget.
17+
In App Terminal widget you can type commands.
18+
'help' - info about available commnds
19+
'logo' - prints blynk library ascii logo
20+
'version' - prints blynk library version
21+
'sysinfo' - prints board system info
22+
'ls' - list target board dir. Example: 'ls /lib'.
23+
root dir will be listed if no arguments provided
24+
25+
For any other terminal inputs will be printed error info that provided command is not supported.
26+
