Open Source Sound Dev / Re: Open Source Sound using Teensy 3.2 and PJRC Audio Library
« Last post by Rongyos on September 05, 2022, 04:07:38 AM »
Hi Tankers!

Very easy but confusing question. Connecting PCB and sound card serial should be like:
TCB RX  - SOUND TX
TCB TX - SOUND RX
GND - GND

Am I right? I attached a picture but I connect it to the wrong connector just for reference.

Regards
Rongyos

Thanks for the tip Luke, just wish I'd checked sooner......I've got three 4.0 teenie's now that are no good to me...no wonder my sound cards wouldn't work!!  I think they loaded okay, just seemed to act a little wierd.  Now to find some 3.2 versions...maybe I'll get lucky :)

I think I've been trying to get 3.2 versions for over a year...

Or a chip with a recorded bootloader. So far nothing has worked.

It's bad that I can't rewrite the program - to another platform.

Hi Rongyos, your questions are not annoying at all!

In fact there are several other Teensy boards that could be made to work with the OP Sound Card firmware, but they would all require significant changes to the code and the physical circuit board. The 3.5/3.6 have nearly the same type of sound output as the 3.2, but they are a physically much larger and would require a complete board redesign. Also the 3.5/3.6 processors are unavailable right now the same as the 3.2, so that is no help.

The 4.0 can also produce sound, but it only outputs the sound digitally. This means that instead of the sound output going straight to an amplifier chip, it would first have to go to a digital-analog converter, and then the amplifier. So again a complete board redesign, and also changes to the firmware.

Unfortunately such a redesign is not something I have the time for. And I can't even say that if someone started on this undertaking there might not be other complications that could arise, as I have not explored in depth all the differences. Even if I had the time, I might be hesitant to take on such a project in the current environment, because who is to say that the 4.0 or other components (amplifers or who knows what) might also be affected by shortages in the near future.

I'm sorry I can't be of more help! But I hope that answers your question.

Hi Rongyos, unfortunately although the Teensy 2.0 can do many things, it does not have the necessary processing power to handle the sound generation. So you will need to use the Teensy 3.2.

I know right now they are not available due to the supply chain mess. The semi-conductor shortage is a real problem, much bigger than I thought it would be when it first started. It does not appear at all close to being resolved. When major car manufacturers in America can no longer make automobiles, I don't know how long it will be before hobby things like the Teensy will be able to return.

Hi Luke!

Thanks for your fast reply. I try to not be annoying, but what about teensy 4.0? It is available at local stores.

Regards
Rongyos

edit: I found this comparison table. The 4.0 version has differenc processor, so I assume this is not compatible for the board but waiting for your confirmation.

Hi fellow tankers.

My sound cards are under assembling and I have a teensy 2.0 at home. Will IT work perfectly or v3.2 is necessary?

ok found my problem; The battery voltage monitor was reading from the regulated 5V not from the battery; change the wire; solved!

Hi,

I have two TCB, one working with my other radiomaster with frsky receiver (that one work fine) and the other one with radiomaster receiver (the one that is bad) (TCB version made with arduino stock board mega2560). with the good TCB all my receivers are working fine with the controller near or not. It is the other TCB that have that strange problem. I have compared my two circuit and they are the same. I may have shorted or damaged the serial RX3. It is possible to change the firmware to use the unnused RX2?
