Help Teensy 3.2 #1

Open DNAcz opened 2 years ago

DNAcz commented 2 years ago

Since Teensy 3.2 is unavailable for a long time it would be possible to use it Teensy 4.0 or another board?This is a very nice project but currently without usable hw.

robthomson commented 2 years ago

Hey.. technically it should work on teensy 4.0 with no issues. Pretty sure another chap built one to work with it.

DNAcz commented 2 years ago

Rob thanks for the quick reply. I have Teensy 3.1 on the way but if it works with Teensy 4.0 that's very good news. Have you tried it? Dan

robthomson commented 2 years ago

Not personally.. but apparently it worked by just re-targetting the code in arduino.

DNAcz commented 2 years ago

Ok. Then I'll try it Teensy 4.0.Thank you again.

I gave this a shot with a teensy 4.0, it still builds and works. i think i had to comment something about a esp32 but it was pretty easy error.

Telemetry and all

robthomson commented 2 days ago

Nice. That with elrs or crossfire?

robthomson commented 2 days ago

Superb. I could never get elrs to work in past. Prob find the teensy 3.2 was the issue

radio-mistress commented 2 days ago

I was able to increase the band rate to 912k as well, I suspect the 4.0 can support the full megabaud rates but the jeti is only going to send 100hz anyways wasnt to important to try that speed.

robthomson commented 2 days ago

Even better.

If you do manage to work out what you changed - send a pull request so we can update the info on the repo!

include

endif `. Is what I had to remove, Im not sure why it was even looking for ESP32 stuff but its simple enough to comment out as its not required.

radio-mistress commented 2 days ago

I can repackage it and do a PR with the increased baud rate and include my tested hex file with a wire diagram for someone who doesn't wanna rebuild the project.

robthomson commented 2 days ago

That would be great. I no longer use jeti so hard for me to even test!

robthomson commented 2 days ago

On the plus side.. This code base is usefull for anybody who wants to do a crsf convertor.

I may at some point do an frsky to crsf transcoder.

Handy for guys who want to relay ther radio to a ground station etc...

radio-mistress commented 2 days ago

I was making that exact comment elsewhere! most of the CRSF implementations are pretty confusingly done and not documented in any reasonable way, much better starting point using this small sketch where the structure cleanly setup. I was thinking it would be possible to open more xfire ports as the teensy 4 has like 5 uarts so it could juggle a few radios and pick the best LQ/rssi. Thats all better off in a separate project, I just got a pair of 2.4 only ds-16 radios for free and figured I could get some airplanes setup, the handset part is so nicely built but these old 2.4 radios are no fun, it drops signal around the workshop can't fathom trying to fly something I want to come back.
