 ===== Übersicht =====

==== IT01 ====
  * **1** **2** **3** **4** 
  * **5** **6** **7** **8** 
  * **9** **A** **B** **C**
  * **0** **S** **T** **N**

==== Neues Modul: 4x4 KeyPad (entsprechend IT01-FrontKeys) ====
  * 8x IOPin: 4x Input(34, 35, 36, 39) und 4x Output(12, 13, 14, 27)



==== LocalSystem ====

  * Kapselung aller System-Variablen (CpuTemperature,...)
  * Collector für Commands/Responses für lokale Hardware-Ressourcen(BreadBoard!):
    * LedSystem
    * LedQuad(Uart1, Wlan, Bt, (Lan))
    * LCDisplayI2C(PCF8574, I2C)
    * Temperature / Humidity(DHT22: CLK, DATA, 5V0, GND)
    * 4x4 KeyPad (entsprechend IT01-FrontKeys)
    * Pressure/Humidity
    * GetChipID (Examples-Esp32-GetChipID)


==== UCSystem ====
  * LCDisplayI2C((PCF8574, I2C)
  * Quertz-Keyboard(PS/2, 5V, CLK, DATA, GND):
