Problem Adding Buttons & required Remote-Control Modules

awwbaker

Thank you, I tried the pinctrl to no avail. Thank you though! Anthony

sdetweil

@awwbaker did you solve this?

@sdetweil Sorry have been on travel last several weeks. No I never did. I have the remote control module in and working just never could not get the button push. I have mmm-GroveGesture installed and working with sensor. Still working towards getting modules to hide and show. Could I ask another question???

What can/should I do on this?:

@awwbaker remote control is loading the main js from other modules, but in the wrong runtime context.

i don’t know why it is doing that

@sdetweil ,
Hmmm…thanks Sam!!!

Hi guys, I’ve been trying to figure this out too. I think I’m close with these two files using ‘pinctrl’ instead of ‘/sys/class/gpio/’ but I can’t figure out what I’m missing.

Based on the console log it looks like there’s an issue in my node_helper file, possible with the socketNotification functions because I’m not seeing any of my test messages.

And based on the log files there may be something missing from the package.json file because sometimes I get this error “Error: Cannot find module ‘node helper’ MODULE_NOT_FOUND” but other times I don’t. And I tried running this fix but couldn’t get it to work.
[https://forum.magicmirror.builders/user/jorickjuh](link url)

Other than that I’m not seeing any other errors and module does appear to be working but it’s just not processing any button presses. I’ll keep trying but I’ll post my progress so far on here in case someone can see what I’m missing.

test file:

Module.register("MMM-PinToggleTest", {
  defaults: {
    pin: 19,
    modulesToToggle: ["clock", "calendar"],
    interval: 1000
  },

//consol.log("MMM-PinToggleTest is starting...");

  start: function() {
    Log.info("MMM-PinToggleTest is starting, sending CONFIG...");
    consol.log("MMM-PinToggleTest is starting, sending CONFIG...");
    
    this.sendSocketNotification("CONFIG", {
      interval: this.config.interval,
      pin: this.config.pin
      });
    },

  start: function() {
    console.log("MMM-PinToggleTest started");
    this.previousPinState = null;

    // Request initial pin check from the helper
    this.sendSocketNotification("CONFIG", this.config);
  },

  socketNotificationReceived: function(notification, payload) {
    if (notification === "PIN_STATE") {
      const pinState = payload;
      console.log(`Received pin state: ${pinState}`);  // Log received state

      // Toggle modules based on pin state
      if (pinState !== this.previousPinState) {
        this.previousPinState = pinState;
        this.toggleModules(pinState === 1);
      }
    }
  },

  toggleModules: function(show) {
    console.log(`Toggling modules to ${show ? "show" : "hide"}`);
    this.config.modulesToToggle.forEach(moduleName => {
      const modules = MM.getModules().withClass(moduleName);
      modules.forEach(module => {
        if (show) {
          module.show(1000);  // Show module with fade-in effect
        } else {
          module.hide(1000);  // Hide module with fade-out effect
        }
      });
    });
  },
  

  getDom: function() {
    const wrapper = document.createElement("div");
    wrapper.innerHTML = "<small>MMM-PinToggleTest</small>";
    return wrapper;
  }
});

node_helper:

const NodeHelper = require("node_helper");
const exec = require("child_process").exec;
//const rpio = require("rpio");
//const Gpio = require("onoff").Gpio;

module.exports = NodeHelper.create({
  start: function() {
    console.log("node_helper for MMM-PinToggleTest has started.");  // Confirm helper initialization
    this.previousPinState = null;
    this.lastChangeTime = 0;
    this.debounceDelay = 200;
  },

  socketNotificationReceived: function(notification, payload) {
    if (notification === "CONFIG") {
      console.log("Received CONFIG in node_helper:", payload);  // Log receipt of configuration
      this.config = payload;
      this.schedulePinCheck();
    }
  },

  schedulePinCheck: function() {
    console.log(`Setting up pin check every ${this.config.interval} ms`); // Confirmation log
    setInterval(() => {
      this.checkPinState();
    }, this.config.interval);
  },

  checkPinState: function() {
    const pinNumber = this.config.pin;

    exec(`pinctrl ${pinNumber}`, (error, stdout, stderr) => {
      if (error) {
        console.error(`Error reading GPIO pin ${pinNumber}: ${stderr}`);
        return;
      }

      const pinState = parseInt(stdout.trim(), 10);
      const now = Date.now();

      console.log(`Current pin state for GPIO ${pinNumber}: ${pinState}`);

      if (pinState !== this.previousPinState && (now - this.lastChangeTime > this.debounceDelay)) {
        this.previousPinState = pinState;
        this.lastChangeTime = now;

        console.log(`Pin state changed to ${pinState} at ${new Date(now).toISOString()}`);
        this.sendSocketNotification("PIN_STATE", pinState);
        
        // Small delay to avoid multiple triggers
        //setTimeout(() => {}, 100);
      }
    });
  }
});

@ChrisLeduex well, you don’t have any source errors. altho you have 2 start: functions in the modulename.js

I see this as output of the pinctrl command on my pi 4

 pinctrl
 0: ip    pu | hi // ID_SDA/GPIO0 = input
 1: ip    pu | hi // ID_SCL/GPIO1 = input
 2: ip    pu | hi // GPIO2 = input

12: ip    pd | lo // GPIO12 = input
13: ip    pd | lo // GPIO13 = input
14: ip    pn | hi // GPIO14 = input
15: ip    pu | hi // GPIO15 = input
16: ip    pd | lo // GPIO16 = input
17: ip    pd | lo // GPIO17 = input
18: ip    pd | lo // GPIO18 = input

30: a3    pu | lo // CTS0/GPIO30 = CTS0
31: a3    pn | lo // RTS0/GPIO31 = RTS0
32: a3    pn | hi // TXD0/GPIO32 = TXD0
33: a3    pu | hi // RXD0/GPIO33 = RXD0
34: a3    pn | hi // SD1_CLK/GPIO34 = SD1_CLK
35: a3    pu | hi // SD1_CMD/GPIO35 = SD1_CMD
36: a3    pu | hi // SD1_DATA0/GPIO36 = SD1_DAT0
37: a3    pu | hi // SD1_DATA1/GPIO37 = SD1_DAT1
38: a3    pu | hi // SD1_DATA2/GPIO38 = SD1_DAT2
39: a3    pu | hi // SD1_DATA3/GPIO39 = SD1_DAT3
40: a0    pn | lo // PWM0_MISO/GPIO40 = PWM1_0
41: a0    pn | lo // PWM1_MOSI/GPIO41 = PWM1_1
42: op -- pu | lo // STATUS_LED_G_CLK/GPIO42 = output
43: ip    pu | hi // SPIFLASH_CE_N/GPIO43 = input
44: ip    pu | hi // SDA0/GPIO44 = input
45: ip    pu | hi // SCL0/GPIO45 = input
46: ip    pu | lo // RGMII_RXCLK/GPIO46 = input
47: ip    pu | lo // RGMII_RXCTL/GPIO47 = input
48: ip    pd | lo // RGMII_RXD0/GPIO48 = input
49: ip    pd | lo // RGMII_RXD1/GPIO49 = input
50: ip    pd | lo // RGMII_RXD2/GPIO50 = input
51: ip    pd | lo // RGMII_RXD3/GPIO51 = input
52: ip    pd | lo // RGMII_TXCLK/GPIO52 = input
53and : ip    pd | lo // RGMII_TXCTL/GPIO53 = input

and this for output of pinctrl 19

19: ip    pd | lo // GPIO19 = input

so the “pinctrl 19” command and parseInt(“19: ip pd | lo // GPIO19 = input”, 10);
will return 19

I think you meant pinctrl get 19, after sometime prior doing pinctrl set

pinctrl help
shows all it can do

ChrisLeduex

@sdetweil Thank you for catching those, too much copying and pasting.

Removed one of the start functions from the module.js file and also updated this line in the node_helper.js file so now it is returning the pin state instead of the pin number.
//const pinState = parseInt(stdout.trim(), 10);
const pinState = stdout.includes(“hi”) ? 1 : 0;

There still seems to be an issue somewhere in my node_helper.js file though because I’m still not seeing anything from that file in the console. Looking through the forum it seems node_helper file issues are common and I’ve tried implementing a few of the solutions I found there but still haven’t found the problem but I will keep trying. I suspect maybe I’m not nesting my socket notifications correctly.

PinToggleTest.js

Module.register("MMM-PinToggleTest", {
  defaults: {
    pin: 19,
    modulesToToggle: ["clock", "calendar"],
    interval: 1000
  },

  start: function() {
    console.log("MMM-PinToggleTest started");
    Log.info("MMM-PinToggleTest is starting, sending CONFIG...");
    this.previousPinState = null;

    // Request initial pin check from the helper
    this.sendSocketNotification("CONFIG", this.config);
  },
  
  socketNotificationReceived: function(notification, payload) {
		if (notification === 'STARTED') {
    console.log("STARTED notification received from node_helper");
    this.config.text = 'Started';
    this.updateDom();
		}
	},

  socketNotificationReceived: function(notification, payload) {
    if (notification === "PIN_STATE") {
      const pinState = payload;
      console.log(`Received pin state: ${pinState}`);  // Log received state

      // Toggle modules based on pin state
      if (pinState !== this.previousPinState) {
        this.previousPinState = pinState;
        this.toggleModules(pinState === 1);
      }
    }
  },

  toggleModules: function(show) {
    console.log(`Toggling modules to ${show ? "show" : "hide"}`);
    this.config.modulesToToggle.forEach(moduleName => {
      const modules = MM.getModules().withClass(moduleName);
      modules.forEach(module => {
        if (show) {
          module.show(1000);  // Show module with fade-in effect
        } else {
          module.hide(1000);  // Hide module with fade-out effect
        }
      });
    });
  },

  getDom: function() {
    const wrapper = document.createElement("div");
    wrapper.innerHTML = "<small>MMM-PinToggleTest</small>";
    return wrapper;
  }
});

node_helper.js

const NodeHelper = require("node_helper");
const exec = require("child_process").exec;
//const rpio = require("rpio");
//const Gpio = require("onoff").Gpio;

//module.exports = NodeHelper.create({
//  start: function() {
//    console.log("Starting node_helper for MMM-PinToggleTest");
//    this.previousPinState = null;
//    this.config = null;
//  },

module.exports = NodeHelper.create({
  start() {
    this.started = false;
  },

  socketNotificationReceived: function(notification, payload) {
    if (notification === "CONFIG" && !this.started) {
      const self = this;
      console.log("CONFIG notification received");
      this.config = payload;
      this.schedulePinCheck();
      this.sendSocketNotification('STARTED', {message: 'test'});
      console.log("STARTED notification sent back to front end");
    }
  },

  schedulePinCheck: function() {
    console.log(`Setting up pin check every ${this.config.interval} ms`);
    setInterval(() => {
      this.checkPinState();
    }, this.config.interval);
  },

  checkPinState: function() {
    const pinNumber = this.config.pin;

    // Execute pinctrl command
    exec(`pinctrl get ${pinNumber}`, (error, stdout, stderr) => {
      if (error) {
        console.error(`Error reading GPIO pin ${pinNumber}: ${stderr}`);
        return;
      }

      //const pinState = parseInt(stdout.trim(), 10);
      const pinState = stdout.includes("hi") ? 1 : 0;
      console.log(`Detected pin state for pin ${pinNumber}: ${pinState}`);  // Log the detected state

      // Only send if state has changed
        if (pinState !== this.previousPinState) {
        this.previousPinState = pinState;
        console.log(`Pin state changed to ${pinState}`);
        this.sendSocketNotification("PIN_STATE", pinState);
        
        // Small delay to avoid multiple triggers
        setTimeout(() => {}, 100);
      }
    });
  }
});

I wrote a little pinctrl script that just outputs 1

#!/bin/bash
echo 1

as pinctrl is not on my linux desktop

ChrisLeduex

@sdetweil Ah yes, I forgot I have a python script I was kicking off manually that I forgot to run before testing those fixes. It is working now and both files are communicating with each other, thank you.

My next step is to see if I can get this working with the MMM-Buttons/MMM-ModuleToggleButton modules.
