I’m sorry, I’m a little confused on how the Teensy 4 is working in all of this. Does it’s size mean that one could get the extra power of the TXo+ firmware without the helper board?

If not, how is the helper board being repurposed to use the Teensy 4?

#1468

Checked it doesn’t work with the hex on the teensy 4

It has to be compiled for the teensy 4

I’ve ordered some pcbs and panels from pusherman. Pusherman didn’t have a special daughterboard available for a teensy 3.6.

Is it required for a 3.6? Do I need one for a 4.0? A different board?

I was planning on making mine a TXO+ - might be hiccup if I have to find a special daughterboard. Anyone know where they are available other than BPC music?

If you see here, you can order the board to be printed by OshPark. It seems extremely reasonable and I’m probably going to do it myself.

They’ll print and send the helper board.

I don’t know anything about the Teensy 4. It’s been hard to get a firm answer from folks if that is possible. Hopefully it is, since that would possibly eliminate the need for the helper board and get me up and running sooner.

Oh man. That’s so incredibly affordable. I had no idea it was just that little board.

Hopefully individuals with a 4.0 can fill us in on their experience!

Yeah, that’s my main thought, the 4 is smaller, cheaper and removes the need for the extra board to be printed. From what I read there is a potentially higher power draw under high stress, which could be a big deal for some.

Either way, I’d like to know the Teensy 4 experience myself. I have an excess of electricity in my case and would appreciate the ease of just throwing a Teensy 4 in my current boards.

Before saying that it works on teensy 4 one has to try to compile the firmware for teensy 4 and test.

If using 3.6 you need that helper board from osh or pusherman in the following weeks…

Hello, does anyone know where or who I can buy a Telexi from in europe? I’m in the UK and I think this is a DIY project but I’ve never held a soldering iron before so am trying to find one to buy heheh

Pusherman Productions has the boards! Lucky for you, they’re located in your back yard!!

Oh, it’s only for the boards. Whoops. But! It’s a pretty simple build!

Thanks but I don’t even remotely understand what I’m looking at haha https://pushermanproductions.com/product/txi-terminal-expander/

A kind friend is going to build it for me :smiley:

Amazing!!! Congrats!

TXi isn’t an especially difficult looking build, even by hand. It seems like a good build to try out SMD soldering if you’re not sure about it.

I goofed up and only ordered 3 of the 4 LED’s if both yellow and white. Can I use some b-grade amazon white and yellow LEDS’s for the time being? Figuring power draw on these isn’t too much of an issue.

I used flat head leds to make it sexy slick :black_heart:

Sorry for the necroquoting, but I’m trying to understand which waveforms are in the Txo+, and from a brief look at the code it seems to be the sine, triangle, sawtooth and then the first 325 waveforms from the Adventure Kid sample pack.

Is that right ?

I’m trying to get a grasp of what is located where in the waveform range, this website seems useful for that but I’d like to be sure of the order of the waveforms.

#1484

To this extent, I am still waiting on my TXo+ helper board from OshPark, but I’m curious, can these waveforms be used in the LFO state as well?

#1485

Yes, and they are great for that!

Edit: I don’t know about the TO.OSC.LFO modes, actually–I always use the various slow TO.OSC.XXX for LFOs, and the waveforms work fine for that.

Can anybody shoot me a link to the female headers they used? I have not found the right ones and even made the mistake of ordering some incorrect ones.

If someone might have an example mouser part or something, I would greatly appreciate it.

#1487

Very close. I skipped AK 10, 23, & 32.

The native waveforms (square, saw, and triangle) are generated computationally with some additional band-limiting techniques on the TXo+.

I only played with the 4.0 briefly and found that the i2c library was incompatible with it. Rather than open that can of worms, I calmly put down the 4.0 and decided to wait until the world caught up a bit.

Anyone have luck with the 4.0? It will be more complex than a simple recompile from source, I think. Please consider it unsupported and stick with the 3.1 and 3.6 for now.

I was wondering which side should be the positive and the negative poles of the LED’s soldered? There is nothing that indicates that on the pcb.
