locoConfigs structure in controller_config.json

[Dirk Schäfer]

Hello,

after a very long time I finally had some time to work on my train layout and to integrate new locomotives.

After uploading the new config files the controller crashed. I realized that the size of the controller_config.json is now larger than 4K. In your documentation you describe that “If your controller_config.json file is too large, use the “locoConfigs” structure to move your locomotive configurations to separate files.”

Can you please give me an example how this has to be done. I assume that there has to be a reference in the controller_config.json and that the separate files of the locoConfigs need a certain structure.

Thank you in advance.
Dirk

Hi Dirk,
I will add some official examples to the source code with the next official firmware release. In the meantime, I will send you some example files via e-mail.

The basic idea is as follows.

The controller_config.json file could look like this:

{
“name”: “MTC4BT-MULT3”,
“espPins”: [
],
“fn”: [
],
“locos”: [
],
“locoConfigs”: [
“/loco_e03.json”,
“/loco_br146.json”,
“/loco_est.json”
]
}

The single files contain the structure that is usually located within the locos array in the main controller_config.json file, e.g.:

{
“address”: 103,
“name”: “E03”,
“speedStep”: 10,
“brakeStep”: 20,
“bleHubs”: [
{
“type”: “SBrick”,
“address”: “84:2e:14:4f:d6:04”,
“channels”: [
{
“channel”: “B”,
“attachedDevice”: “motor”,
“direction”: “forward”
},
{
“channel”: “D”,
“attachedDevice”: “motor”,
“direction”: “reverse”
}
]
},
{
“type”: “SBrick”,
“address”: “84:2e:14:51:79:8b”,
“channels”: [
{
“channel”: “A”,
“attachedDevice”: “motor”,
“direction”: “forward”
},
{
“channel”: “D”,
“attachedDevice”: “motor”,
“direction”: “reverse”
}
]
}
],
“fn”: [
{
“name”: “f2”,
“device”: “bleHub”,
“address”: “58:8e:81:58:b2:00”,
“channel”: “B”
}
]
}

Voila.

Hi Matthias,
this works perfectly. And it is even more convient than a single config-file. Thank you.
Have a nice sunday.
Dirk
