Setting Up Multicolored Lights MTC4PF

[Todd Bowers]

I set up multicolored LED’s under 0.4 firmware on one of my trains and was able to use the Function buttons in RocRail to turn on either red, blue or green and use the automatic lights while running. I updated to 0.5.1 and now I can only get F1 to light. When I checked to Serial Monitor, F1 shows pwm of 1023 (max), but F2 and F3 only will be 0 pwm when triggered. How can I fix this setting? Below is a copy of the Serial Monitor:

I realized my error. I was using the wrong configuration file.

Hello everyone.

In the last past days i’m struggling to config train light, but no success.
I have following config:
– hardware – MTC4PF with battery (ESP 8266 12E, and motor shield L298N)
– two led (white and red) with common plus terminal. I soldered minus terminal of white to minus of wihte, for red the same
– pin D0 to common minus white
– pin D2 to common minus red
– D3, D4 to L298N motor shield motor A
– motor connected to PF motor A
When train direction is in reverse red light is running normal (white is OFF). When train direction is FW or stop condition both light are ON.
When hit F1 both light are ON, on F2 only red is ON.

What i’m doing wrong?

The config is this:

// *****
// LOCOS
// *****

// Number of locos (aka. MattzoLocos) controlled by this controller
const int NUM_LOCOS = 1;

// List of MattzoLocos
// The parameters have the following meaning:
// – locoName: name of the loco as setup in Rocrail
// – locoAddress: address of the loco as setup in Rocrail
// – accelerationInterval: time interval for acceleration / braking (default: 100 ms)
// – accelerateStep: power increment for each acceleration step
// – brakeStep: : power decrement for each braking step
MattzoLocoConfiguration* getMattzoLocoConfiguration() {
static MattzoLocoConfiguration locoConf[NUM_LOCOS];

locoConf[0] = (MattzoLocoConfiguration){

// – in1..in4: pin for motor direction control for motor shields L298N and L9110 (in1: forward motor A, in2: reverse motor A, in3: forward motor B, in4: reverse motor B).
// – minArduinoPower: minimum power setting for Arduino based motor shields
// – maxArduinoPower: maximum power setting for Arduino based motor shields (max. 1023)
// – configMotorA: turning direction of motor A (1 = forward, -1 = backward, 0 = unused). In case of LEGO IR Receiver 8884, this is the motor connected to the red port.
// – configMotorB: same for motor B; if IR receiver: blue port
// – irChannel: if a LEGO IR Receiver 8884 is used, the selected channel of the receiver. May be 0, 1, 2 or 3. If the loco uses multiple IR receivers on different channels, additional motor shields for the loco are required.
