No, sorry, I did not know this was not a known issue. I am using Big Sur (I think). When I changed the board manager to use Teensy 4, the loader came up on compile. Seems like something got stuck when I switched back to...
I had to rollback the beta Teensyduino before I could test it with the Teensy 4, because I could not compile my project for the LC with that beta.
(Also, noticed Teensy Loader would not launch.)
I will try it again...
Hello,
I am working on a hobby project using I2C for an OLED display and SPI for an SD card reader plus 3 digital potentiometers.
For the Teensy 4, the SD reader does not initialize. It's one of those super-cheap...
I'm seeing some weird scrolling using the Adafruit_SSD1306 (with 128x32 OLED Display) with I2C on my Teensy LC. (Never mind how slow this runs on the LC)
It seems like there's a small offset error and the bitmap keeps...
One final question on this thread.
I am trying to use an SPI SD card reader. One of those really cheap, one-bit ones. It works on my Uno.
I am trying to use Teensy 4 pin 14 for CS. The test code is showing that...
Hah! Never mind my comments. I can't help myself. The truth is this kind of development is the Wild West, and I would not have it any other way. I like figuring out how to get multiple devices to work together. I am...
Seems like libraries need to do a little more to support multiple spi devices. Like, my program opens up SPI, and then I ask each SPI device library for their respective settings. Then I get to manage and orchestrate...
Hello!
I see my Teensy has multiple sets of SPI pins. Can I run SPI on more than one set of pins simultaneously?
The documentation suggests no. It seems SPI is a "Singleton": One instance per application. I can...
Thanks! I have not tried eagle, yet. I downloaded kicad but could not figure how where to begin... I am sure CAD, like all other tech things, is something we talk about like there's a universal workflow, but I bet every...
I had an analog drum synth with a Teensy 4 delivering metal noise for cymbal and high hat sounds. It’s an insultingly simple task for the Teensy 4 I admit (trivial to add knobs and midi), but MQS works great for that...
It's a new year, and time to try new things.
If I want to get a PCB made, maybe a very small batch, what files do I need to send? Is it just a PDF? How good do they have to be? To me, this is one of those things...
As Jacquot noted in his write-up, this is pretty much an "MVC" application, so I de-coupled the user interface, the sound generators, and the sequencer. In that state, the voice.cpp file exports all the percussion synth...
I am interested in simulating the resonant filters.
I had the old Arturia Storm software and they did a decent job with ringing filter percussion.
I'm going to assume the existing Teensy Audio Library filters...

Started single-board computing on the Tessel (1). Then tried Adafruit wearables, then moved to the Arduino Uno, and now very happy with the power of the Teensy platform.
