Hi Martin,
as I wrote earlier, The ICE #7897 and the green crocodile #7898 are in my opinion beautiful trains of the Lego train family. The best option would be to convince Mattzo to add it to the MTC4PF, based on Visual Studio code. Martin, did you do your work on Arduino or on Visual studio code? Maybe Mattzo can write his opinion about it. I still hope, that Mattzo adds the trains to the MTC4PF.
best regards
Herbert

Hallo Mattze,
Danke für die Info,das ist jedenfalls ganz toll. Meine Bitte war aber eher, dass du die IR Befehle vor Power Functions (7897,7898 – schwarze Fernbedienung) aufnehmen könntest. Das wäre sicher für ein umfassendes Lego Projekt sehr wichtig.
Liebe Grüße
Herbert

Hallo Matthias,
könntest du mir – und somit natürlich der gesamten Lego Community – einen großen Gefallen tun. Aus meiner Sicht sollte es einfach sein, den LEGO_IR_8884 Code um 4 weitere Einstellungen/Kanäle zu ergänzen (nur IR). Die Züge 7897 (wunderschöner ICE) und 7898 (grünes Krokodil) lassen sich auch mit IR steuern. Es gibt 3 Kanäle und einen 4. für 1 bis 3 gemeinsam.
Es gibt nur + und Minus Taste (funktioniert 7 Mal – somit 7 Geschwindigkeiten) und Stop Taste. Jeweils Plus drücken wird der Zug eine Stufe schneller bis zum Maximum (dann kann man zwar weiter drücken, aber der Motor wird nicht mehr schneller), mit Minus drücken wird er langsamer bis er rückwärts wieder bis zum Maximum fährt. Dann gibt es noch die Stop Taste.
Wenn die Befehlsstruktur gleich ist wie beim Power Functions, müsse es einfach sein, das Programm zu erweitern. Wenn es bei PF mehr Geschwindigkeitsstufen gibt, könnte man ja einfach welche doppelt verwenden, damit man das Programm nicht adaptieren muss. Man könnte einfach statt den Kanälen 0-3 (PF), die Kanäle 4-7 in deinem Programm verwenden. Lichter gibt es sowieso nicht, je Kanal somit nur 1 Sender. Da kann man einfach standardmäßig Null setzen. Leider kann ich nicht C programmieren und verstehe das Programm zu wenig.
Die Codes in Hex hätte ich mal ermittelt:
1+:390C76EE
1-:5CF0E634
1stop:F3F4DCF8
2+:1D1F21E0
2-:7D769E4F
2stop:1E61B965
3+:1695FECD
3-:7672B3A
3stop:29F6DFB4
All+:4B7BA39F
All-:B0D3CC54
Allstop:D1637DA9
Einige waren nicht 100%ig eindeutig. Aber die 2. Möglichkeit habe ich noch und könnte einfach mal testen.
Ich hoffe, die Adaption ist so einfach wie ich mir das vorstelle. Wäre jedenfalls eine tolle Erweiterung, speziell, da ich dann 3 Züge mehr verwenden könnte.
PS: Dein Tip mit den IR Sendern war korrekt. Ich kaufte deine Modelle bei Amazon und alles lief perfekt. Jetzt warte ich gerade auf 100 reed sensoren:-)

liebe Grüße & Gratulation zu diesem wirklich tollen Projekt

Thank you for the info. I will buy this type too.

Actually I used 2 different types:
LED 5mm Infrarot klar 10-40mW/sr 13 7 0,49 3,43
183338 LED-KREATIV-SET S081 IR-LED 5 MM (set of receiver and transmitter)

Hello Forum,
I have a problem with this controller. Mayby someone has an quick idea.

My situation: MattzoSwitchController: up and running, MattzoTrainControllerPU: up and running, Problem: MTC4PF: Train is not responding (only once there was a little move of the train)
My configuration: Train with LEGO IR 1884, Motor on red and lights on blue, Standard ESP8266 MOD 12-F from AZ Delivery,only one IR LED soldered on D5 and GND (short leg), power supply: 9V on VIN and GND,
Also tested: a second board with another type of IR LED, both boards also testet with 5V (USB)
The Mattzo Controller looks to be working perfect and send the right commands (see protocol)
Possible problem: I only measure 0,14 V on the IR LED when it is working. It is supposed to has 1,35V. But I have no idea what could be wrong. I tested everything twice with a second board. The power supply of the board is ok (3,3 V on 3V3 and GND).Maybe the value “const int MAX_AI_VOLTAGE = 5100″; is too low, but I didn’t want to change this. It comes from the example file
Has anybody an idea?

Find there the protocol from board and the config file:

Hi Max, thank you for your hint with the Boot/Rst pins. So far I have not even noticed them. I’m a beginner with microcontrollers.So you really have to write some tutorial for Mattzo and Arduino/Controllers. But my problem is still not solved. When uploading everything looks good to me: these are the last messages from Arduino

When I press Boot/RTS, the flashing and rebooting stops, but now, the monitor writes the system is waiting for download again:

so it is in infinite loop, pressing Boot or Reset by itself had no effect, so far from Arduino I got correctly the MAC Adress, but an original boot with the Mattzo Controller ID did not happen. Right now, I have only one ESP32, so I cannot change the hardware. Any Ideas?

Hi, unfortunately I ran into a problem and I am not able to solve it. I managed to include the libraries. The compilation is without errors. The upload works – the AZ Delivery ESP 32 is blinking red. But the controller keeps rebooting with following message:Rebooting…

line 267 is a counter for the number of Locos, I set it 1 in the config file
Can anybody help me?
One more question. I have to set the IP adress for the MQTT. Is it “localhost” if it is running on the same Win 10 Notebook. Where do I get it?

[Herbert S.]

Hello, I am new here and very enthusiastic about the idea. So today I have ordered a lot of controllers, reed sensors and other stuff. I have two questions: I have an white ICE 7897 and a green crocodile 7898. These work with IR, but this system was published befor power functions. So is it or will it be possible to control them with an MattzoTrainControll with IR-LED? The second question is about your future plans für the MattzoLayoutController and the new train controller. Will it be the same hardware (ESP8266 / ESP 32) or are there plans to change?
