Adapter Interfaces and IDE Improvements

[franz-hoepfinger-4diac]

@jwalt and me talked yesterday about Adapters: #4diacwinterschool

i am quite interested in this Topic, and already started some Discussion with @azoitl and this Thread i want to use to Discuss the Ideas:

Naming:

unidirectional Adapters

AB: unidirectional Adapter Interface for 1 Event and 1 Byte

AE: unidirectional Adapter Interface for 1 Event

AX: unidirectional Adapter Interface for 1 Event and 1 Bool

bidirectional Adapters

AB2: bidirectional Adapter Interface for 1 Event and 1 Byte

AE2: bidirectional Adapter Interface for 1 Event

AX2: bidirectional Adapter Interface for 1 Event and 1 Bool

IDE Features

Fan-Out and Fan-In of Adapter.

the IDE shoud give possibility of Fan-In and Fan-Out of Adapters.
today this is already possible, but requires a Adapter-Adapter:

Splitting Adapter

today you need to make an extra FB for Splitting

like E_SPLIT, but E_SPLIT is not used anymore, because the IDE handles this.

This I can think only for the unidirectional Adapters

Boolean Operations

for AX, we can then make very nice Boolean Operations:
