CS6021

iPad Remote Controller for Märklin Central Station in ControlUnit-Design

The Idea behind the app:

Look and feel of the old Märklin digital components on your iPad
Implemented devices: CONTROL_UNIT, KEYBOARD and MEMORY
Functionality behind buttons are translated in background to CS commands (sent via network requests)
Multiple instances of each device possible for faster access (i.e. one CONTROL_UNIT commands one locomotive)
MM and DCC support (MFX only via access to lists in CS)
Support for all Central Stations: CS3, CS2, "fakeCS2" and later for CS1/ESU (for they use a different protocol)
App to run only on tablets, as screen on phones would be not sufficient at time of development start
Remove the limitations of original devices:
- more than 80 addresses selectable
- more than 4 functions accessable
- not only MM protocol
- remind speed/function-status of locomotives
- enable multi tractions of locomotives
- maybe even programming of CVs

cs6021's Issues

Add Edit-button at MEMORY to change Accessory/group

This could also be achieved via long-push on the corresponding red/green switch button

> 4 Functions for DCC & MFX Decoders

Could be implemented maybe by ScrollView for the function buttons (except function/off !), which then is blocked for MM2 decoders (they only support 4 functions)

Locomotive functions should be blocked at CONTROLUNIT, while new number is not entered completely

Add keystroke sound to be played when any button in the app gets pressed

UIDevice.CurrentDevice.PlayInputClick();

Add wipe gesture to switch between tabs

At least one instance of each virtual digital component must remain, when list gets deleted by user

Add debouncing/delay to transmission of speed ?

Problem: If speed slider is moved, this causes many commands to Central Station and therefore a lot of traffic on the CAN bus

Read out locomotive list from Central Station not implemented

Read out locomotive list from CS
--> ListViewTable should show up the locomotives name instead of the MFX number

This could be called by user interaction:

Sync/Get button at upper left of TableViewList
pull TableViewList down

IP address / hostname of central station can not be set

IP address / hostname should be stored on device persistently
If connection at startup of app fails (after timeout), then the user should be asked to enter IP address / hostname via popup window. If connection can be established with new IP address / hostname, then this should be stored persistently.

Idea: At startup of the app we send a broadcast to all network devices and check each device weather it is a central station or not (via status request)

user info missing, that MFX locomotives can not be edited in app

Only MM and DCC numbers should be editable. As MFX numbers are administrated by the Central Station, this should not be editable in the app.
Once a locomotive is registered at the Central Station and the MFX-Number is stored, then the user can update the locomotive list in the app (which brings up the locomotive in the TableViewList) and then control the locomotive.
