Hi all, i'm wanting to do 48-bit timing on a Teensy 4.0. The only way i can do that is to use the QUADTimers and cascade them. After testing the QUADTimers i was able to determine that they run at 150MHz and based on the largest value i will need to use i have decided to run the timer at a...

Hi all, just a quick check to see if it is possible to adjust the size of the emulated EEPROM on the Teensy 4.0. I'd made my project on the 3.2 and was able to get 6 save spaces for settings out of it, but since the 3.2 is out of stock i have moved to a 4.0 and now can only get 3 save spaces...

Hi all, i've been looking into using comparators for a project and the libraries i can find don't have enough flexibility for me so i have been looking into setting the registers myself to get the results i want. I'd like to use comparator with the filter off, in continuous mode, with...

Hi all, i am working on a project which uses a SSD1306 display connected to a Teensy 3.2. At first i was updating the display whenever something happened which should cause the display to be updated. That didn't work and i've now gone to a different approach which is to just update the...

Hi all, i've been trying to get hardware SPI to work for my SSD1306 (Adafruit Monochrome 1.3" 128x64 OLED graphic display - STEMMA QT / Qwiic) display on a Teensy 3.2 but with no luck. I've been trawling the posts on this forum and looking for alternative pinouts for the 3.2 but with no luck...

Hi all, my Teensy 3.2 was resetting and i couldn't figure out why. The Teensy is being used to run 4 clocks for modular synths which all have various settings. One of the functions i've built is for one clock to reset another when it gets back to the start of its loop. This will keep clocks...

Hi all, i've been puzzling over this for a wee while and can't figure it out. I have a mono jack socket with a normally closed tip-switch. The socket is for input voltages. I want to detect whether there is a jack connected using the tip-switch but can't figure out how to do it. Does anyone...

Hi all, i am wanting to connect a small USB keyboard to a Teensy 3.2 which should only SEND data to the Teensy 3.2. No data needs to be sent to the keyboard. I can power the keyboard using my supply rails (+5V and Ground) but then the info needs to come from the keyboard to the Teensy and...

Hi all, i am using Teensy 2.0 and Teensy 3.2. On the Teensy 2.0 there is a Tx and Rx pin. In this case i assume i use "Serial" to instigate a serial connection. On the Teensy 3.2 there are Tx1/Rx1, Tx2/Rx2 pins etc. In this case i assume i use "Serial1", "Serial2" etc to instigate a serial...

Hi all, i am compiling some code in the Arduino software for loading onto a Teensy 2.0 and i get an error message telling me that there is an error with the timers e.g. "'TCCR2A' was not declared in this scope" All of the errors seem to relate to Timer2. Isn't there a Timer2 on the Teensy...

Hi all, i've been looking for this data but can't find it.. Maybe you can help? I am using an external (not USB) 5V power supply to power my Teensy 2.0. I am using switches going into digital pins and potentiometers going into analog pins. Before i turn it on i want to check about the...

Hi all, the Teensy 3.2 has 2 ADC's which connect to different pins. I want to set up some analog pins with a different resolution than the rest but to do that i need to know which pins relate to which ADC. I can't find anything that gives me that information so i am wondering if anyone knows...
