MMM-Swipe - Hand gestures

mochman

@Mitchfarino Looks almost all good. I’m not sure if you have your trigger pin hooked up to ground from this picture. The pins in the config are not the actual pin #'s of the header. It uses the GPIO#. I use this picture as a reference.
RP3 GPIO

As an example you can see that pin 32 is called GPIO12. If you connected your Trig wire to that and your Echo wire to GPIO16 (physical pin 36). In the config.js you would use :

echoLeftPin: 12,
triggerLeftPin: 16,

and then a similar setup for your other sensor.
If you are still having issues with the setup, please let me know.

As a reference point, your red wire is connected to physical pin #2.

@mochman I have a problem when installing the modules. When I enter the module in the config. When I start the Magic Mirror I get the following error message and a white screen.

@BeLuGe Have you run npm install in the MMM-Swipe folder? Are you running the mirror with sudo? If so would you mind posting your config.js file. Thanks.

BeLuGe

@mochman Yes I have run npm install in the MMM-Swipe folder. I running the mirror without sudo.

@mochman I’m only just back looking at this

Any tutorial I find online says I need a breadboard too - is that correct?

What pins should put these in? Or where can I find resource on how to do it?

mochman

@BeLuGe So I just tried this myself. When I created the module, I was connected to the pi to test. I just tried using SSH to start the program and got the same error you’re getting. Looks like it’s a issue with running a sudo command over SSH, the workaround I found was to run sudo cp ~/.Xauthority /root/ then run DISPLAY=:0 sudo npm start. The problem with this is that everytime you restart your mirror you will need to run the copy command again.

@Mitchfarino You don’t need a breadboard. I just used one to test out my configuration. You can hook it up directly to the pi using those wires you have already connected. When I tested out my setup, I used these pins.

echoLeftPin: 24,       
triggerLeftPin: 23,     
echoRightPin: 26,      
triggerRightPin: 25,

Remember that those are the GPIO #'s and not the physical pin #.

Mitchfarino

@mochman I have vcc, trig, echo and gnd on my sensor - how do they map to the config you have posted?

mochman

@Mitchfarino

Your left sensor

Vcc goes to pin #2
Gnd goes to pin #6
Trig goes to physical pin #26 (Which is labeled GPIO 23)
Echo goes to physical pin #18 (Which is labeled GPIO 24)

Your right sensor

Vcc goes to pin #4
Gnd goes to pin #9
Trig goes to physical pin #22 (Which is labeled GPIO 25)
Echo goes to physical pin #37 (Which is labeled GPIO 26)

You need both sensors if you want to detect movement.

Mitchfarino

@mochman OK, I’m an idiot!

I only have one sensor! Ha

Thanks very much for your help, I’m gonna get one ordered then get back on it.

Sorry for the daft questions

mochman

No worries. Yeah the sensor looks like it has 2 detectors on it. I’m pretty sure one is the speaker and the other is the microphone detector.

Can you make another config.js file with just the MMM-Swipe module in there? I don’t know what the:
WARNING! Could not load config file. Starting with default configuration. Error found: Error: Module version mismatch. Expected 49, got 48. means.

BeLuGe

@mochman I change the config file to default and add your Module. The same errormessage.

mochman

@BeLuGe Try running rm -rf node_modules/ inside the MMM-Swipe folder then running npm install again.

BeLuGe

@mochman I have delete the directory and install the packages with npm install
And I have reinstall the complete Raspberry and install only your module.
The error is still there

mochman

I can’t help you then. That was my last option. I don’t receive that error nor do I know what that error means.

bob123bob

@mochman and @BeLuGe can you tell us what are the versions you are using :
Raspbian Jessie or Wheezy, which version of nodes, npm … ?
From where are you running npm start (local, ssh) using sudo or not ?
I have the same issue as @BeLuGe and I would like to debug/understand what’s is the problem.
I already red it could be a nodejs version issue (compiling vs running version)
So guys tell us what are your configuration

Here is mine :
Rpi 3 updated firmware with rpi-update
Raspbian Jessie last version (apt-get update && upgrade && dist-upgrade)
Nodejs last version 6.5.0 ARM version (not sure if it’s 64 bit or 32 bit) from https://nodejs.org
Then install of MM and packages
MM is working fine until I add MMM-Swipe module configuration then got same error message about
Error: Module version mismatch. Expected 49, got 48.

Hope we will find the solution …

BeLuGe

@bob123bob I use Raspbian Jessie last version, Nodejs 6.5.0.
I have test it with Nodejs 5.11.1, the same issue.
I run MM without sudo.

mochman

I’m running:

RasPi 3 with Jessie
NodeJs 6.7.0
Fully updated with

sudo apt-get update
sudo apt-get dist-upgrade
sudo rpi-update

I just removed the entire MMM-Swipe Folder

cd ~/MagicMirror/modules/
git clone https://github.com/mochman/MMM-Swipe
cd MMM-Swipe/
npm install
cd ~/MagicMirror/
sudo npm start

I don’t get any of those errors. I don’t know what module version 49 is?

Jopyth

@mochman Similar issue here. They changed the package.json to fix it. Seems to be a problem with a new Electron version.

You would only get this error if you newly install Magic Mirror (npm install in the MagicMirror folder gets the new package, if you want to reproduce it).
