Particle Ethernet Featherwing (with Xenon)

[jjdeprisco]

I’m using a Xenon (OS 1.5.2) with a Particle Ethernet FeatherWing. I’ve got the Xenon’s Ethernet capability turned on via the Particle mobile app, and the Xenon is recognized by Particle.io (logged on via my mesh network via an Argon). Ethernet is plugged in on the Particle Ethernet FeatherWing - getting blink light - and ready to test.

I’m using the sample application sketch provided by Particle here:

Pin configuration - Ethernet - Ethernet | Reference

// SAMPLE APPLICATION
#include "Particle.h"
SYSTEM_THREAD(ENABLED);
SYSTEM_MODE(SEMI_AUTOMATIC);
Serial1LogHandler log1Handler(115200, LOG_LEVEL_ALL);

retained uint8_t resetRetry = 0;

void setup() {
#if HAL_PLATFORM_WIFI && !HAL_PLATFORM_WIFI_SCAN_ONLY
    // To force Ethernet only, clear Wi-Fi credentials
    Log.info("Clear Wi-Fi credentionals...");
    WiFi.clearCredentials();
#endif // HAL_PLATFORM_WIFI && !HAL_PLATFORM_WIFI_SCAN_ONLY

    // Disable Listening Mode if not required
    if (System.featureEnabled(FEATURE_DISABLE_LISTENING_MODE)) {
        Log.info("FEATURE_DISABLE_LISTENING_MODE enabled");
    } else {
        Log.info("Disabling Listening Mode...");
        System.enableFeature(FEATURE_DISABLE_LISTENING_MODE);
    }

    Log.info("Checking if Ethernet is on...");
    if (Ethernet.isOn()) {
        Log.info("Ethernet is on");
        uint8_t macAddrBuf[8] = {};
        uint8_t* macAddr = Ethernet.macAddress(macAddrBuf);
        if (macAddr != nullptr) {
            Log.info("Ethernet MAC: %02x %02x %02x %02x %02x %02x",
                    macAddr[0], macAddr[1], macAddr[2], macAddr[3], macAddr[4], macAddr[5]);
        }
        Ethernet.connect();
        waitFor(Ethernet.ready, 30000);
        Log.info("Ethernet.ready: %d", Ethernet.ready());
        resetRetry = 0;
    } else if (++resetRetry <= 3) {
        Log.info("Ethernet is off or not detected, attmpting to remap pins: %d/3", resetRetry);

        if_wiznet_pin_remap remap = {};
        remap.base.type = IF_WIZNET_DRIVER_SPECIFIC_PIN_REMAP;

        remap.cs_pin = D10;
        remap.reset_pin = D6;
        remap.int_pin = D7;

        auto ret = if_request(nullptr, IF_REQ_DRIVER_SPECIFIC, &remap, sizeof(remap), nullptr);
        if (ret != SYSTEM_ERROR_NONE) {
            Log.error("Ethernet GPIO config error: %d", ret);
        } else {
            if (System.featureEnabled(FEATURE_ETHERNET_DETECTION)) {
                Log.info("FEATURE_ETHERNET_DETECTION enabled");
            } else {
                Log.info("Enabling Ethernet...");
                System.enableFeature(FEATURE_ETHERNET_DETECTION);
            }
            delay(500);
            System.reset();
        }
    }

    Particle.connect();
}

void loop() {
    static system_tick_t lastPublish = millis();
    static int count = 0;
    static bool reconnect = false;

    if (Particle.connected()) {
        reconnect = false;
        if (millis() - lastPublish >= 10000UL) {
            Particle.publish("mytest", String(++count), PRIVATE, WITH_ACK);
            lastPublish = millis();
        }
    }

    // Detect a network dropout and reconnect quickly
    if (!reconnect && !Ethernet.ready()) {
        Log.info("Particle disconnect...");
        Particle.disconnect();
        waitFor(Particle.disconnected, 5000);
        Log.info("Network disconnect...");
        Network.disconnect();
        Particle.connect();
        reconnect = true;
    }
}

When I compile this, I get several errors:

Anyone have any thoughts on where to start with troubleshooting? Issues seem to be in the code provided. Just trying to get a positive test that the Particle Ethernet FeatherWing works.

That code will only work with Device OS 3.3.0 and later, which have FEATURE_DISABLE_LISTENING_MODE and pin remapping. Neither of those features are implemented in 1.5.x.

Since you’ve enabled Ethernet support, you shouldn’t need any of the extra code.

OK, thanks. Will look into this further.
