-PSA1259 hardware control using the DeviceController DC2
-
-covering enclosure (switches and doors) and money devices,
-controls mifare card to access or program
-optional it can control printer, modem, bar code reader and credit card
-
- * API to the PSA1259 Hardware
- * All data come in from device controller via serial interface and will be stored
- * in "PI" = peripheral image
- * PI is updated every 100ms (up to 30ms possible)
- * This api uses stored pi data and returns them in the following functions
- * created: Q1/2020 TS
- *
-
-The devices, connected to device controller2 (DC2) can be controlled in different access levels.
-Level 1:
-    direct connection to DC2, check versions, state and parameters
-    control serial interfaces
-    digital/analog IO's
-    read and write to connected devices on lowest level, this is a kind of fall-back-level
-    in case higher levels fail or do not support the needed (new) function
-    Example: send a specific printer command, several bytes that need to be conform to
-            printer manual. This command is routed to the printer through the DC2 without
-            any action of the DC. You can write your own device driver that way.
-    Level 1 is flexible but complicated
-
-Level 2:
-   The DC controls the connected devices containing a device driver. The DC offers
-   usage of the device by simple commands,
-   Example: "Printer on", "set Font size 3" "print "hello world"", "cut"
-   In opposite to level 1 where you had to send a set of numbers and letters.
-   In other words: you "talk" to the device controller, not to the device itself.
-
-Level 3:
-    start/stop complete processes.
-    Example: 1) print (predefined) document nr 3 with Text, letter size, font set, cut.
-                Also power up/down the printer, check if paper ok and so on.

-Another access example: control the coin unit
-
-Level 1): read digital inputs to detect coin,
-          switch digital output which opens coin slot
-          communicate with coin checker by certain mdb-commands (manual conform)
-          poll coin checker for inserted coins
-          close coin slot after 3seconds by setting DO to 0....
-
-Level 2): get message of attached coin from DC
-          send command "initialize coin checker" to DC
-          send command "open slot for 3s"
-          poll DC for inserted coins, DC polls coin checker in right way, no need
-                to know the data sheet of the coin checker or mdb-bus
-          command to DC "open coin escrow's return flap for 1s"
-
-Level 3): send command: "start payment process"
-          all coin devices are started up
-          coin blocker opens for 3s if a coin is attached
-          coin checker summarizes inserted value and reports sum
-          later send command "stop payment process" (puts coins to vault) or
-          send command "cancel payment process" (returns coins to user)
