Yea, it’s a mystery to me as well - I just know doing the manual refresh works very reliably.

I’ve had this problem on a stock pi3 b and a pi3 a+ - initially, I thought it was related to the low memory issues on the pi3 a+ - but as I update to use this new module from older ones I’ve seen it again on a stock 4gb pi3

I have this same problem with Ext3Agenda - manual refresh always works.

Sometimes waiting works - I’ve waited for 4 hours and suddenly have items appear. Waiting for refreshInterval doesn’t work - I can see the module/refresh with no data even though the calendar has broadcasted the items.

My current workaround is to wait for a few minutes and then use MMM-RemoteControl to connect and refresh the browser using that module, which in my experience works 100% of the time

CX3? I’m still using OG CX …

I couldn’t get CX2 to do what I was doing with CX so I never upgraded at all - it still runs, but it does have trouble parsing some kinds of calendar items.

I use OG CX to do

1. A single Day scrolling view for my 7" “Desktop MM” - not much screen space on the 7" screen so can only show a single day on one half in a scrolling loop

2. A 3-day view for the Kitchen Family Screen - an entire week makes things too small so you cannot see easily - a 3 day view fits nicely though and can use a nice large font

I’ll agree that CX2 was crazy complicated to configure though - and I gave up trying to get it look like I wanted.

I use a 7" touchscreen Pi as a “desk assistant” running MagicMirror. I keep a scrolling calendar for the day on one half, and I rotate the other half through a bunch of panels using mmm-carousel.

You can simulate a lot of what this Google device does, however, it’s likely to be quite hard to get the touchscreen working in a similar way. Swiping, tapping, etc, bringing up a keyboard - these are all things Android does very seamlessly and easily. MagicMirror just doesn’t have the support for those, unfortunately.

I spent some time trying to get some gestures to work - I wanted a “double-tap” to turn on and off the screen - but wasn’t really able to make much progress because the basic support for it in electron just wasn’t there

But good luck on this project, I think this is a worthwhile goal and I’ll be following your progress

Love it!
Installed it on the family info board, and the kids think its great.

For those using the official 7" display you can use MMM-Screendimmer

Or write directly to /sys/class/backlight/rpi_backlight/brightness

I don’t have any ideas for you, except to say that I never even thought about trying this - I’m going to try it on my Samsung tv!

I would reduce the config down to the default, and then eliminate modules to see if anything works.

I’m terrible with the soldering iron but here is what I did

I used a 12v 5a power supply with the same board - you don’t have to stick with 3a, that’s a minimum recommendation for the controller. So getting a 5a power supply should cover easily the controller and the rpi.

In the spec sheet you posted, see where it says CN3 on page 4 &5. This is an optional connector that may (or may not) be on the board.

Pins 3 & 4 are 5v and 5 & 6 are GND.

Note, however, unless you want to do some simple PCB soldering this isn’t the way to go. What I did was attach some header pins to the board, cut one end off a USB cable and attached it to the pins, then plugged it in the normal way into the RPi.
