Dec 10, 2013 · Once Paul releases a Teensy 3.1 schematic, I will be able to confirm that - but it seems logical. The two MCUs on the Teensy 3.0 and 3.1 have all the same physical port/pin mappings, except for pin 18 gaining a DAC0 output on the '256 version of the chip. View attachment 1176 So, a couple of caveats apply before blindly jumping into production:

Jan 20, 2014 · I've undertaken the task of getting a Matlab digital filter onto the Teensy 3.1 because of its onboard DAC. I've been using Matlab at my Uni and have designed a filter using the FDAtool and i think i can get the M file from it. Its a simple butterworth filter nothing special All i …

Apr 26, 2014 · Hello guys, I have been working on a Teensy 3.1 pinout diagram. I have tried to make a little interactive example, in order to get some feedback. Here is a link to version 0.1: external link to Teensy 3.1 Pinout Diagram (Just press the big [Grey] buttons on the example page). Any suggestions...

Jan 6, 2015 · The Teensy 3.1 has a real time clock (RTC) built-in. You will need to solder a 32.768 kHz, 12.5 pF crystal to the Teensy. If you hook up a 3v coin cell battery to the Vbattery/ground pings on the back of the Teeny, it should keep the RTC powered for several years, even if the rest of the Teensy is not powered.

Nov 28, 2014 · Teensy 2.0 and Teensy++ 2.0 are 5V only, or they can be configured for 3.3V by adding a MCP1825 regulator, but in that mode they become 3.3V only. On Teensy 3.2, the 5V tolerance is on the pins with digital I/O, even when used in analog mode.

Dec 24, 2013 · That is a 5V part but will accept the TX from the 3.3V Teensy 3.1 CPU alright. So you need +5 for the transceiver VDD and of course connect the common of the Teensy to VSS on that part.

Jul 13, 2014 · I've recently developed a new take on this board: the Teensy-Arduino crossover board. Simply put, it's a Arduino form factor board containing all the Teensy 3.1 components (making it perfectly compatible with the Arduino IDE and Teensy loader) and adding some features such as 5V analog in and high-power, low-noise 3.3V lines.

Aug 26, 2014 · Hi All, I have an apparent problem with the USB connectivity of the Teensy 3.1 Boards. I am using them to drive a large number (1920) of WS2812B pixels, using the OctoWS2811 Library. My hardware setup is as follows; 1) 1 x Teensy 3.1 Board, buffered with a 74HC245 for 5V compliance...

Apr 6, 2014 · Only for Teensy 3.1/3.2. Periodic conversions There are two ways to do periodic conversions: using an IntervalTimer or using the PDB. It's possible (and easy) to use the IntervalTimer library with this library, see analogReadIntervalTimer.ino in the examples folder. Teensy 3.x have the PDB, supported on both ADCs, see the adc_pdb.ino example.
