mixin services

[pelikhan]

These are services that augment existing module and are connected to "parent" service. For example,

• [ ] LED inside an Arcade button

• [ ] analog position reader in a analog servo

• [ ] position encoder in a motor

• [ ] matrix keypad + LED matrix

• A auxiliary service is defined in the sub range 0x4...

• Auxiliary services must be following the parent service immediately in the control service list.

control
servo
|-- analog reader service
arcade button
|-- led service

Other idea:

-- light service
-- matrix keypad
--- matrix keypad light service

[0] control
[1] matrix keypad light service --> 2 sub services following me
[2] matrix keypad
[3] light service

• let's call them mixin services, see https://en.wikipedia.org/wiki/Mixin
• let's use 0x2.... range

We are not doing this.

[mmoskal]

Well, I think we are, just not quite yet.
