Approaching - DIY norns shield

Barnabe42 · 2019-12-05T05:32:33.386Z

HI,

Yes it is confusing, I have an pcb from AtoVproject and they claim to support I2C.

The 16n is a fader bank sending CV, I2C, MIDI jack compatible with all standards, USB MIDI (compatible PC, Mac, iPad etc…)

It could be as you said that it is just a plug conversion type… it was too good to be true

You are correct - the 16n faderbank does support i2c. However, Norns and Fates (I believe) do not have native i2c jacks.

The way to use the 16n with Norns/Fates would be USB MIDI, and it works great with my Norns!

More info on i2c in this thread.

It works!!! thanks a lot @tehn Never found the fault unfortunately, ended up just starting again.

Hello,

Can anybody check it they have the same issue.

Just installed the update of the diy shield and it doesn’t start up anymore. Before the update no prob. Update was 2010…

I checked with another sd card with older firmware and it starts up again.

I’ll reformat the sd card and burn the image again.

Thx

Just checked the sd card and it works so I think it is software related

Is there a way that I can revert the update in some way?

My Shield is from Monome, i did the update for the wifi some days ago, no issue…

Which Pi do you use? 3b, 3b+ ? Mine is a 3b+

(Just in case it could be related to the Pi version as there are changes to the /boot/ files apparently…)

I use on the non starting one RPI3B but now I baked a new SD CARD and it works.

Bizar

I wonder if it might be possible to disable a core or underclock something on the Pi 4 to drag it away from the ‘desktop replacement’ class of power/performance/heat trade-off and more towards a high end embedded device?

Happy to test on my 2GB and 4GB models once I get my shield built!

I’ve been using a fates on a raspberry pi 4 for several weeks and I’ve not hit 70 degrees celcius once, maybe the norns apps, designed to run on a pi 3, aren’t really taxing the cpu on the 4?

vcvcvc_val · 2020-01-19T20:50:45.495Z

Oh that’s lovely to hear!

mcpepe · 2020-01-19T21:10:25.060Z

Do you have a fan installed?
Or any heat sink on the CPU?

robotfunk · 2020-01-19T22:02:57.854Z

20 characters of nope

That’s great news!

whoa!

want to post the file? how much did that cost??

I draw the file but then a whole process went on with giving to a wizard in machinery.

The file is possible and he asks if you want it flat in dxf file or in 3d, in step / iges / sat… you name it

Price is me making a shield for him
