Hi,
I've got a TeensyLC button box which used to output via USB as a game controller.
And then I started tinkering before reading any manuals. It now doesn't output anything. It does work, I've been playing with...
Consider the following code. In a nut shell, one function launches the other on a timer, and the other then delays for some time and then cancels the timer. This is running on a Teensy 4.0

Hi,
The following is to ask about a speed up for looping over transfer16() with some other operations in between calls to transfer16(). The essential is that there seems to be about 150 nsec between calling...
Hi all, I've spent the last year fine-tuning a Teensy 4.0 with a music fader sketch, and after long months of tweaking, found just the right settings for a balanced system. Faders do not output unwanted MIDI, and a...
Hello, I am attempting to use the ILI9341_t3 library on my Teensy 4.1, but I get only a white screen and nothing else. The code used is the graphics test, but the display shows nothing but white. For a moment, it did...

I need to use an external 16bit 1MS/s ADC over SPI with the Teensy 4.0. We are going to assert the CONVERT and read the 16 bit data over SPI, hopefully at 1 MS/s.
Will the SPI library support reads at this rate on...
Hello there!
We are trying to develop our own code to read data from a BNO086 IMU by CEVA, using I2C and Teensy 4.1. We read the datasheet and understood all the main points of the CEVA's SHTP and SH2 protocols. We...
The Audio Shield has been out of stock for some time, so I thought I'd post a quick update.
First we couldn't get the 32 bit version of the SGTL5000 codec chip. So we bought the 20 pin version and redesigned the...
I'm starting this thread as a blog.

Hi,
The Teensy 2++ was recognized by PC before, but today it is not. It doesn't run the program when I press the button. There is power (5V) detected from the Teensy board, which means the connection should be fine....
I've got this encoder that a buddy pulled off a log processor head. It's apparently used to measure a tree as it's being cut up. His controller is in-op and a new one is quite expensive. He was wondering if I could...
I'm using a teensy 4.1 for synchronizing and time-stamping of sensors, as such consistency of the timestamping is important.
I bought an RV3028 RTC (1ppm,...
Hi
I'm using Serial6 and Serial7 to send and receive 8 bytes of data each at around 6Mbaud on teensy 4.1. I think the the buffer might be overloading because when I run the program at a much slower baud rate the...
Hi all -
I'm seeing if I can implement an EGM96 geoid model on Teensy 4.x. Specifically, I'm implementing this library:
https://github.com/emericg/EGM96
I renamed the EGM96.c file to a .cpp file and moved the...
Hi all,
I've got a gigantic sketch over 30,000 lines of code in a Teensy 4.0. As might be expected I'm running out of memory for files, to the point I'm getting concerned I can continue development of the product...
I'm trying to track down a horrible situation where when I write 32 bytes out Serial5 (115200) to a TTL<->RS485 module which then sends it to a LORA DTU - my main code halts SOMEWHERE in a reasonably complex main loop....
Here are two code snippets, they run from loop. Again, this is a contrived example do demonstration what seems like a bug.
The first works perfectly okay. The second hangs at SPI.transfer16. What I am doing...
Hi,
I have a costum pcb and have Serial3 buffered to 5v connected to a MAX-485 dmx output. I was having some problems with my code only working after recompiling and using the reset button on the teensy 4.1 and when I...
Hi,
To make a long story short, I borrowed some code from a project ( https://github.com/jacqu/teensyshot ) to generate a DSHOT signal. I'm currently adapting this code for my own project using a Teensy 4.1 board....

Really not sure where to post this. It seems this might be the best subforum, but feel free to move it to a better location if appropriate. Been on 1.8.19 for quite a while now. Thinking of upgrading the IDE to the...
I'm using @KurtE's ILI9341_t3n library. This is how I construct a rounded button with text. Here is one of many cases on a switch(buttons) statement. I iterate through the buttons.
case 7: { // Zero Z button

String currentkey;
void setup() {
delay(3000); // just to make sure I don't get stuck in a loop
currentkey = MODIFIERKEY_CTRL;
}
void loop() {
Keyboard.press(currentkey);
}
A trimmed down example.
