MMM-usonic Problems

[sdetweil]

@sdetweil that module (mmm-usonic) is not for magic mirror, but a library for a potential module to use to talk to the hardware…

sadly has same labeling and same verbiage (module)

he wrote MMM-Swipe, which uses his library (mmm-usonic)

@sgarg15 to fix the electron rebuild problem,

the package.json file in MMM-Swipe and change

this

    "postinstall": "node_modules/.bin/electron-rebuild -e ../../node_modules/electron-prebuilt"

to this

    "postinstall": "node_modules/.bin/electron-rebuild"

[sgarg15]

@sdetweil So the install worked properly but then when i ran sudo npm start it gave this error

[1580:0329/130746.224199:FATAL:electron_main_delegate.cc(211)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

Any idea what that means?

[sdetweil]

@sgarg15 what version of electron are u running?

[sdetweil]

@sgarg15 do NOT use sudo, just npm start

[sgarg15]

@sdetweil I am pretty sure i updated the electron yesterday using npm install --save-dev electron@latest

[sdetweil]

@sgarg15 do not use sudo

[sgarg15]

@sdetweil Oh ok i was just following the instruction, so i used npm start and now it has another error

Any Ideas?

@sgarg15 something to do with the MMM-Swipe config info

[sgarg15]

@sdetweil But it is the same as the one in the readMe

readme:

	{
		module: 'MMM-Swipe',
		position: 'bottom_left',	// Doesn't matter after it's setup.  It should be blank.
									// Best results in one of the side regions like: bottom_left
		config: {
			// See 'Configuration options' for more information.
			echoLeftPin: 24, 		//Left Sensor's BCM Numbered Echo pin - REQUIRED
			triggerLeftPin: 23, 	//Left Sensor's BCM Numbered trigger pin - REQUIRED
			echoRightPin: 26, 		//Right Sensor's BCM Numbered Echo pin - REQUIRED
			triggerRightPin: 25, 	//Right Sensor's BCM Numbered trigger pin - REQUIRED
			useAsButton: false,		//Enable a GPIO output when you "press".
			buttonPin: 8,
			verbose: false,		
			calibrate: false	
		}
	}

My config:

	{
		module: 'MMM-Swipe',
		position: 'bottom_left',	// Doesn't matter after it's setup.  It should be blank.
									// Best results in one of the side regions like: bottom_left
		config: {
			// See 'Configuration options' for more information.
			echoLeftPin: 27, 		//Left Sensor's BCM Numbered Echo pin - REQUIRED
			triggerLeftPin: 24, 	//Left Sensor's BCM Numbered trigger pin - REQUIRED
			echoRightPin: 23, 		//Right Sensor's BCM Numbered Echo pin - REQUIRED
			triggerRightPin: 22, 	//Right Sensor's BCM Numbered trigger pin - REQUIRED
			useAsButton: false,		//Enable a GPIO output when you "press".
			buttonPin: 8,
			verbose: true,		
			calibrate: true	
		}
	},
