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...

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.
