Use SYSTEM>UPDATE on device, then rerun the diy device patch.

You can pull from git sources and recompile but you might get something “in-between” rather than an “official” release.

The serialosc compile thing might be a good candidate for its own question Thread

#567

Coming back to this after I stopped looking for a solution from frustration:

My neotrellis worked, it functioned with my Norns Shield. Then I created the case to grid, and all of a sudden it stopped working. I ordered a replacement Teensy, flashed it, still nothing. Which leads me to think that there’s a problem with the neotrellis cards, but I’m not sure how to explore this further without a logic analyser (let alone the knowledge to use such a thing). The test script does nothing either.

Now the connections are all good, I’ve bleeped them with my DMM, so are there any places to check for errors that people have encountered. The biggest frustration is that it simply stopped working without any interventions by me. I thought I might have been a little rough with the teensy, but that is the one thing that seems to be working still.

#568

Maybe the first neotrellis board you connect to is borked. Have you tried connecting the cable from your teensy to any of the other trellis boards to see if you get any response?

I’d opt for it being a bad neotrellis board. I ordered 16, 6 were broken. Friend ordered 8 and one was non-functioning too. Tested with both the teensy and circuitpy scripts individually! I think there’s some QA issues with these things?

Thought I was going crazy for like hours, couldnt even get the I2C scanner to discover them, even got one broken board to connect to openOCD so not sure what’s up with them :sweat:

just the standard method of using environment variables

export CFLAGS="-g -O0"
./waf configure
./waf build

then you can

gdb build/bin/serialosc-device 
(gdb) b main
(gdb) r

etc

I had a moment where my case was pushing the reset button of my teensy, causing my grid to freeze. Definite head scratcher that was frustrating. Hopefully it’s something that simple.

This thing is driving me nuts.

So, it was a broken teensy after all, but also the connector to the boards was broken. I’ve now soldered wires to the neotrellis pads directly, and am getting the light again signalling that the grid is working. My PC then says setting up device “monome”. So far so good.

But now my Norns Shield doesn’t recognise the grid anymore. It doesn’t work with it. One step forward, two steps back.

#573

This is the story of DIY in a nutshell. But hopefully each step back leads to a greater understanding that will pay dividends in the future

Did the shield work with the neo-grid previously? Have you updated the norns software since then?

You may need to re-run the diy device fix? Instructions here

I didn’t update, but will try this anyway. Yes it worked before.

#576

Does anyone have the neo-grid case files in dxf or another open vector format? The .ai/eps files won’t open for me in my cad software unfortunately, and none of the converters I can find seem to want to work for them either.

#577

revised version as dxf - scale is millimeters

neotrellis-128-13.dxf (1.1 MB)

#578

You’re amazing, thanks. Would love the same on the fates case file if you have the chance, but regardless I appreciate all the help you’ve offered so consistently. :+1:

hm, today (unfortunately as i’m working on a video including it that is due) my diy grid seems to have died. after being plugged in, one of the corner lights flashes for a second then it seems nothing… does this sound familiar to anyone?

#580

So if the corner light blinks, it’s not “dead” - that means it’s completed it’s startup process.

What are you connected to?(and what’s happening or not happening?)

#581

a fates - yesterday I was happily using it with MLR, but today when i go into devices and select it, it shows “none”. tried 3 usb cables so far

#582

Try to restart (sleep/power-cycle) Fates with the grid connected

It’s helpful in this situation to have maiden open and look for error messages.

Sometimes the neo-grid will not be recognized by the norns software. I am kinda hit or miss on why - usually unplug replug or a restart with it plugged in (or not plugged in) will fix it.

#583

wow, after a couple of restarts with and without it plugged in, clearing it from the devices list, restarting plugged in, and adding a new grid worked. thanks for the pointers. my project is saved :wink:

HI All.

Trying to build a 32 ( 4 x 8 ) Neotrellis grid with Arduino Uno.

Im done soldering the first half 4 x 4. its connected with jack ( no interrupt)

this is the thing:

If I load the SeeSaw example it only recognaizes half the grid.
it could be the top half, the bottom or any side… all connected with the top left neotrellis.(meaning the boards work fine and the connections too.

could it be a power thing? should I wire vin and groud to different points?
Im only using the power from the arduino uno (with the power jack).

any help?

#585

How do you power supply that arrangement?
