LocalSystem

Kapselung aller System-Variablen (CpuTemperature,…)
Collector für Commands/Responses für lokale Hardware-Ressourcen:
- LCDisplayI2C(PCF8574, I2C)
- Temperature / Humidity(DHT22, iopin)
- Keyboard versuchen:
  - Paul Stoffregen Arduino-Library PS2Keyboard
  - PS2Keyboard

CommandReceiver(relative to Esp32)

PC-[Uart1]: Command↔Response
PC/Tablet/Handy-[Wlan]: Command↔Response
PC/Tablet/Handy-[Bt]: Command↔Response
Extension later: PC-[Lan]: Command↔Response

Dispatcher(relative to Esp32)

LocalSystemDispatcher[Spi, I2C, Gpio]:
