Question I have for you intelligent individuals. I have the teensy 2.0 soldered directly to a raspberry pi A+ without any headers. This works fine if I plug the teensy into any other device including other pi's. However if I'm connected to the A+ it does not detect the teensy. I'm guessing due to the constant power to the teensy. Is their any workarounds to get the pi to register the teensy?
Or do I need a fet that turns the teensy on via gpio?
Whoops my bad, I can take better pictures when I get home. Power is not permanent as I'm currently having issues with it. But it goes as follows for this leg.VeteranGamer wrote: ↑Fri May 10, 2019 1:50 pmTinkerman92 wrote: ↑Fri May 10, 2019 11:09 amGood afternoon ladies and gents.

what are you powering the whole build with.....
if you could show how you have it all set up....

After tinkering with it last night I believe the pi has a faulty USB controller. Because the teensy works on all other computers and Pi's. But to answer your question. We decided to not use a hub for this build so the setup is a bit goofy. The pi and teensy have both had their headers removed and are soldered directly to the board.VeteranGamer wrote: ↑Fri May 10, 2019 3:52 pm(I appreciate that this is still a WIP)Tinkerman92 wrote: ↑Fri May 10, 2019 2:38 pmWhoops my bad, I can take better pictures when I get home.

but at first glance you seem to have somethings going on there that will give you headaches when coming to close the whole thing
we'll leave that for another time
how are you connecting the Teensy to RPi? (please clarify)
it should be wired to the Raspberry Pi USB port (either directly or via a USB hub).....
you could try just wiring the data connections (D+ & D-) to the RPi, and drawing the power directly from the Retro PSU

Put a cheap ac filter on the power input to the audio amplifier to get rid of any noisejbenedetto84 wrote: ↑Sun Jun 02, 2019 5:44 amHello all. Just wanted to say my build is complete and working nicely. Big thanks to @VeteranGamer and @Helder for their help and support as this was not the easiest of builds. The ONLY thing that I can't seem to fix is the static in the speakers whenever the PI's activity light is blinking (this has more to do with what it's processing than the LED itself; just to be clear). I've wrapped all speaker wires in conductive fabric and added toroids and it makes no difference. It's only noticeable during boot and shutdown so I've grown to accept it. It most likely has something to do with the pot being so close to the retro psu and as the pi demands more current a feedback is picked up. In my next build I will try to keep them further apart. I will be posting photos/videos of my build shortly.
Thanks! I will try that and let you know how it goes.banjokazooie wrote: ↑Sun Jun 02, 2019 10:17 amPut a cheap ac filter on the power input to the audio amplifier to get rid of any noise
