....Aaaannd you are correct. The ST7735 code works perfectly. Wow. Thank you!

My bad - it is *literally* the stock program, ubnchanged at all (I assume you wrote?) but here is the correct info: Code I used is the examples like: /* This example was adapted from ugfx http://ugfx.org It's a great example of many 2d objects in a 3d space (matrix transformations) and show...

I bought ten of these units on the advice I received here, and have yet to get a single one working. I've used an arduino duemilanove, another identical unit, and three different Arduino Nano boards. Tried four different TFT screens (red PCB, yellow pins) and now that I'm finally not getting...

Sorry for the delayed response - I was up until 5 AM last night soldering stuff for John Cusack. Long, random story :) I'm doing this stuff now. Thank you!

Oh, and thank you.

That must work better than "Teensy unamplified audio output", "Teensy guitar amplifier amplifier output" et la like I was doing. Although when I used the search term you just said, I didn't get even close to the same results. ... although granted, I've never really used Bing. I'm guessing...

Sorry, you guys must hate me with all these questions. One more, I'm noticing some gain issues. Is there an output besides the 1/8th inch jack that's NOT amplified? My amp is expecting an unamplified signal, and I think it's causing some issues (insane amounts of feedback for one). Should I...

Great! Hopefully the RAM I ordered (should arrive in a few days) will help with that, or maybe I can even store some on that SD card? I guess we'll see. I am currently stuck on the last (and one of the most important) parts of the tutorial. I have been tearing my hair out trying to get my...

I've been fighting with this thing for a week, and I cannot get it to work. It's a brand new 124x68 blue and yellow 0.96" OLED at address 0x3C. Here's a link to what I bought (last week, it's brand new, but I have yet to see any signs of life since the code keeps giving me errors)...

I've spent the better part of the day searching the forums and Internet for this answer, so sorry if I missed something. Before I go reinventing the wheel, is there already code that lets you select between these effects, and perhaps display that info on a screen? Right now I'm uploading...

It seriously just opened up not just a whole new world to me, but multiple new worlds. I spent a few hours going through it, and Paul was right - I already have the Teensy+audio board installed in the guitar and I'm rocking out. It's also controlling a pretty slick OLED screen and is about to...

Paul - first thing, you're right - doing the workshop was exactly what I needed. I've learned so much. Thank you. Second - wow. Thank you. Not just for this workshop, but for the Teensy itself. What an absolutely amazing piece of hardware (and software!). Third - Thank you again for...

Nevermind. Found the diagram on a different site. Thanks!

I'm sooo in over my head here. I'm gonna do my best and report back, though. :) Thanks!

I'm off to the races here, but one quick thing: Defrag, this tuner you mentioned - I've spent the better part of two hours searching and I'm not coming up with anything. Little help? Any search terms or anything like that if you don't have a direct link. Sorry to be a bother, I'm sure it's...

I'm on it, Paul. I'll report back when I'm done. Thanks!

Working on this for the next week or so. I'm hoping me posting updates and questions in this thread will be OK? Thanks again to everyone for the help.

And just to clear, here's what I'm working with in terms of hardware. First group is the hardware I plan to use, second is hardware I have and can use: Teensy 3.2 (x12) Teensy Audio Board (x2) 128*64 OLED SPI/I2c/IIC yellow and blue (x2) OR 128*128 color TFT (x4, on order) 3400 mah LiPo with...

Defrag, I just ordered multiple ones of that screen - nice, dude. Thanks. And I was not aware that library existed. I will try to find it. So far my learning curve has been kind of a line...:) Gremlin I had seen the GUI, and it makes zero sense to me. None. I've watched that video multiple...

It does SPI and I2c, I will probably use SPI since it's faster. I've already built in the battery and charging circuit, you can plug in the USB to of course upload code to the Teensy, but the jack works double duty as a charger for the onboard LiPo that's good for about 3000 mah (many hours of...

Oh, and while I'm asking for the moon. I'm also wanting it to have a built in tuner and EQ. Yeah. Long run goal is to print pick guards for popular guitar models with this kit installed as a plug and play turnkey solution to nerd up a guitar. I honestly don't even know where to solder inputs...

Hey, guys. I've recently purchased a few Teensy 3.2 units, an audio board and one of the 128x64 oled displays. I want to build all three of these things into a fender guitar along with a power source. What I'm hoping to accomplish is to have a few to many basic guitar effects built in to the...
