Status of the project/code?

[TrainzLuvr]

Hi,

What is the current status of the code?

I checked out your dph4 branch (since it seemed the most current) and built the DPH-OlcbBasicNode project on an Arduino Uno with a CAN-BUS Shield, as a proof of concept.

I am not sure what should be happening though?

I thought, while looking at your videos on YouTube with those learning demonstrations from several years back, that this basic node would do something similar. What I get is the Blue led constantly on, Gold blinking, and the two LED/buttons on the first two ports are always on.

Activating any of the buttons does not appear to be doing much. I've double-checked my pin assignments and I'm fairly confident that they are correct, not overlapping with pins already in use.

Granted, I have not tested my node on a real OpenLCB network, but I have plans to do that soon (I bought several RR-CirKits modules for my layout to get my feet wet in LCC). I do see a lot of traffic (congestion) on the CANbus, judging by the solid RX/TX LEDs on my CAN-BUS shield.

Is there some place where I can read about the API requirements, specifically why those methods in AT90can.h (https://github.com/dpharris/OlcbRefresh/blob/dph4/libraries/AT90/AT90can.h) are being used and passed to OLCB? (my txReady() might not be working correctly as I keep getting buffer full).

Hi -

I am just now getting back to it.

The blue/gold buttons were initially designed to let one choose an event, and then teach a new one to it. They are basically being abandoned, since for boards with more than a dozen events it becomes onerous to set through them, and much easier to use a Tool (JMRI or equiv.)

The blue and gold LEDs are also used for use feedback. They indicate bus activity when idle.

Probably better to email me directly.

Here's the blue gold blinking for activity, in loop():

void loop() {
    bool activity = olcb.process();    // Process system
    #ifdef USE_BG
        if (activity) blue.blink(0x1);  // blink blue when a frame was received
        if (olcb.can_active) { 
            gold.blink(0x1);            // blink gold when a frame sent
            olcb.can_active = false;
        }
        blue.process();      // handle the status lights  
        gold.process();
    #endif
    //produceFromInputs();
}

Thanks for the code snippet.

Originally I was able to flash an UNO with one of the examples in your repo, though I wonder what is the bare minimum chip for your library (knowing that OpenLCBmini/Arduino Lite will be something on the level of ESP32).

The Refresh should suit from Uno with MCP2515 and AT90CANs to ARMs and ESP32. Not aimed at Pis or OSs.

So includes: Teensy, mbed, Nucleos, Tivas, ESP32.
