Has anyone ordered the aluminum top and bottom panels from Front Panel Express recently? Am I good to simply open the files in FPD and order from there?

Hi,
Im going away for some time and today i plugged my 16n (berlin Modular Version) and updated it with the latest firmware on the github.

When i connect it to teletype via i2c, and do fader x etc… my teletype read values from 0 to -32767, if the fader is in the middle it reads 9559

How can i adjust this range?

Thanks!

Please consult the Teletype manual and look for the FADER.CAL.MAX and FADER.CAL.MIN instructions.

#619

Thanks @desolationjones will do, cheers

I’m afraid I don’t know much about the I2C end of things - I just make sure it doesn’t get changed in releases - so I hope @desolationjones’ advice has helped.

Hi @desolationjones !
I have been trying to get my head around using the 16n via i2c with teletype. When using fader.cal.max and min should i place them on the init script or the metro. I have tried both and i’m quite confused.
Sometimes i set all the fader of the 16n all the way up and run Fader.cal.max on the init script, but then where should i place fader.cal.min? souls i run one (max) set the fader to the top and then set the fader to the min value an run fader.cal.min?
Since i’m mapping lots of teletype things to the fader on the 16n if these are not right, well things don’t work as expected, since i’m using fader.scale on a lot of parameters.
Thanks a lot!

Oh, neither! You should run them once (manually from the live screen) and then leave it alone because the values are stored in Teletype memory. Then you only need to recalibrate if you change devices or notice issues.

Hi @desolationjones thank you so much for the quick response and for the info!
Just did it for all the faders and we are golden! Thanks for your support!

How are most folks connecting i2c to ER-301? Mounting a little TRS jack to a blank panel?

Depending on which of my small cases I’m using I’ve done different things.
For my Pod 60, I drilled a hole in the back( between the small power bus boards) and mounted a jack there. For my Palette I made a cable which connects to the TRS MIDI jack. And for my 7U/62HP typewriter case, I made a small panel for the 1U row.

I just straight up squeezed a wire out the side of the modules, since I don’t use racks (I use floating nuts instead) and usually have 1hp on the side:

I built the 16n AtoV version and it was spitting out midi values and looked to be working 100%. Then I wired the I2C to my TXb and tried reading the faders with my teletype. The faders give crazy numbers, -13264, 6023, 13168… not monotonic, but stable (number stays the same if you leave it alone). Each fader has similar behavior. What should I check? I2C wire is too long, but it can’t be responsible for this…

#629

from what i remember, the latest teletype firmware doesn’t read the value correctly, you need to calibrate it in teletype, using ops FB.CAL.MIN and FB.CAL.MAX

yes that happened to me i too, you need to calibrate it

Thanks @indraperkasa and @thopa, that was it. Saved me hours in my hot garage? Who owns the 16n github site - I’ll ask them to add a note. I searched the teletype manual for 16n and calibrate yesterday, and didn’t find this option.

These ops are not listed in the PDF version of the Teletype manual but so far only in the online version.

#633

I do.

More than happy to add a page on the wiki/docs if somebody could suggest some content? I don’t own a teletype, nor am I particularly up on II-style I2C, so that part of things always is a little bit ‘behind the curve’.

It could also be that I’ll add a link in the editor to that page - if people are messing around with the firmware calibration, they might not realise they need to do something on their Teletype. But an issue on the GH repo with suitable content would be welcomed.

#634

Just a comment that to use the 16n with teletype, you need to slide all sliders to 0, and type FB.CAL.MIN 1, FB.CAL.MIN 2 …16. Then slide them to their max limit and repeat with FB.CAL.MAX 1 … 16.

#635

Can you run a loop? like

L 1 16 : FB.CAL.MIN I
L 1 16 : FB.CAL.MAX I

??

I don’t remember how i did it on mine now :frowning:
