Hi,

Just set up the MTC4PU with the 0.3 firmware. Worked flawlessly!

Hi Max,

Thanks! For the moment I have decided to build Signal, Switch and Sensorcontrollers (and those all work flawlessly 🙂 ). Once I have my track running I will come back to the Layoutcontroller as they definitely are the better solution!

Hi,

I did run into the same issue as Zoltan and Chris. I am also using the AZDelivery ESP32 Dev Kit C V4 NodeMCU.

I was wondering: on which ESP32 NodeMCU does the 0.4.1 version of the code work?

Regards,
Rob

Hi Max,

Yes, everything is connected to a breadboard. When programming/flashing the ESP8266 I use the USB-port of my computer. When starting it up I use an iPad-charger which supplies 2,1 A.

Hi,

I switched to the MattzoLayoutController without the PCA9685. I successfully setup the controller with switches on D0, D1, D2, a signal on D4 and D5 and two sensors on D6 and D7. However, as soon as I connect a switch to D3 I cannot program/flash the controller anymore. From the internet I understand that this has something to do with the voltage of the pin. Being a newbie, I don’t understand how I can program it when a switch motor is connected to D3. Any help is greatly appreciated!

Hi,

I am trying to setup a MattzoLayoutcontroller with the PCA9685. I’m struggling a bit with the setup in rocrail. I have 5 switches and 3 signals attached to the PCA. The switches are on ports 0 to 4, the signals on ports 8 to 13. When I use these ports in rocrail, I get the following message on the serial com: “Message disgarded, as this controller does not have such a port.”

Does anybody know what the issue is here?

Thanks,
Rob

Hi Mattze,

Thanks! I will disregard it then.

Hi,

First I would like to say what a really cool thing the Mattzocontrollers are! I have the Signal, Switch and MTC4PF up and running and am really excited about it.

I have a question on the resistors for the MTC4PF though. I ran into the same issue as Piet Beneke: I only have the 4.7k and 22k Ohm resistors. In one of the replies I read that the important thing is that the ratio between the two resistors should be 4. After reading the code, I wondered whether one could also change the code in the following way:

Replace: const int VOLTAGE_MULTIPLIER = 20000 / 5000 – 1; // Rbottom = 5 kOhm; Rtop = 20 kOhm; => voltage split factor
By: const int VOLTAGE_MULTIPLIER = 22000 / 4700 – 1; // Rbottom = 5 kOhm; Rtop = 20 kOhm; => voltage split factor

Would that work?
Regards,
Rob
