SSSR Labs SM010 and Teletype

since this is now getting linked from other places… could you post in that thread and suggest people should check with sssr labs, as only they can provide the answer?

Will do. Being newish, I follow blithely.

thanks! i posted my findings here back when i had the module, i don’t have the module anymore and i don’t have any new info. just want to make sure this thread is not used as the authoritative source of information.

Hello
If possible can someone please guide me as to how to connect sssr sm010 with teletype and get it up and running
Thanks

SSSR Labs SM010 and Teletype Monome

he just posted a new 1.2 firmware on the web-site which includes i2c support. the teletype side of things is also done, i will post a beta later this week, just trying to finish a couple of things before i do. to connect use the connector marked CN1 REMOTE, the legend is below. please note SCL and SDA lines are swapped on SM010 compared to TT, make sure to connect everything correctly! (ground to ground, SCL to SCL and SDA to SDA). [image] list of ops: MA.SELECT 1..3 set current matrixarc…

Yes I’ve read the thread before
Do you remember how to set the address on the sm010 side of things
I believe I have everything set except for that
And I cannot find anything in the sm010 manual
Thank you

found old notes - to select one of the 3 addresses go to setup, row 15 is where you select it (A/B/C). on teletype side you select it with MA.SELECT x where x is 1, 2 or 3. this is not stored in flash, you’ll need to put it in the init script if you’re not using the default address 1.

Thank you i still got nothing tho
Does anyone remember if it Is still only 3 wires for I2c ?

scanner_darkly · 2019-06-18T16:43:55.039Z

twenty characters of yes

Hello so sorry to bug again
Does anyone know how to hook this up with teletype?
I’m having an extra difficult time
I believe I have I2c connected properly
( 3 wires I swapped the sda and scl on sm010)
I went to line 15 on sm010 setup selected unit 1
I type in ma.select 1 on teletype
Next I try
Ma.step 1, the teletype responds with 1
What am I missing?
Thanks in advance if anyone can help

you don’t need a parameter with MA.STEP, it always advances by one step. have you tried other ops? double check i2c lines - GND to GND, SDA to SDA, SCL to SCL. do you have any other devices connected to i2c? do they work? finally, update sm firmware to the latest - 1.1 version doesn’t include teletype support.

Thank you again and again

FWIW I just got a Matrixarchate direct from SSSR Labs (ordered before I saw this thread) and I can reproduce the row 13 issue. It is extremely easy to mitigate though, a dummy plug in 13 fixes it.

I don’t have it in the same case as Teletype right now but I look forward to trying out the TT integration in the future!

scanner_darkly · 2019-06-24T04:36:41.493Z

can you post what the problem was? might be helpful for others.

they really ought to add this to the module description…

After much pain and agony I’ve come to realize
(For now)
I can not have my txb connected to I2c for it to work
All modules are jumped in order like everyone told me in a previous thread.
My sm010 is now at the end of line
In order my I2c is teletype, txi , txo, jf, w/, sm010
I now would like to connect my txb somewhere along the path and have not found a placement in the chain that works.
The Problem for me appears to be the txb at the moment
Any help would be great
Thanks

Do not power your TXb.
Connect it as near to Teletype as possible.

Duksos · 2019-06-28T16:37:32.969Z

It is not powered should I?
And I was just pondering revising my post and asking if that’s the problem

desolationjones · 2019-06-28T16:48:51.929Z

Which revision of Teletype hardware do you have (check which PCB color)?

Duksos · 2019-06-28T16:55:47.561Z

It appears to be black or a darkish green

desolationjones · 2019-06-28T19:23:36.577Z

Ok. Your bus capacitance is probably just too high with that much stuff attached. Try to reduce cable lengths where possible. If that doesn’t work then try it with your TXb plugged in to power. This will significantly reduce the pull up resistance but hopefully not so much as to create problems…
