Produktbeschreibung

Neuer Artikel: Teensy v3.2 USB Board mit Pins - MK20DX256 ARM Cortex-M4

Teensy 3.1 has the same size, shape & pinout; is compatible with code written for Teensy 3.0, and is well supported on the Arduino IDE using Teensyduino. Teensy 3.1 adds several new features, due to an upgraded microcontroller. Here are the highlights. A table of technical specifications is show below.

More Memory For Awesome Projects

The RAM has quadrupled, from 16K to 64K. While 16K is plenty for nearly all Arduino libraries, 64K allows for more advanced applications. Icons and graphics for color displays and audio effects requiring delays, like reverb and chorus, will become possible on Teensy 3.1. Flash memory has also doubled, to 256K, and provides double the
memory bandwidth.

5 Volt Tolerance on Digital Inputs

Today most new chips use 3.3V signals, but many legacy products output 5 volt digital signals. These can now be directly connected to Teensy 3.1's digital inputs.
All digital pins are 5 volt tolerant on Teensy 3.1. However, the analog-only pins (A10-A14), AREF, Program and Reset are 3.3V only.

12 Bit Analog Output

Teensy 3.1 has a proper analog output. You can always filter PWM, but true analog output responds rapidly. The output is created by the stable reference voltage, so it's doesn't vary if your power supply voltage changes slightly.

Two Analog to Digital Converters

With analogRead(), you can measure many signals, but only 1 at a time. Teensy 3.1 has a second ADC, so you can concurrently measure 2 analog signals. For stereo audio or power monitoring, sampling both left and right, or voltage and current at the same moment is very beneficial. PJRC is developing an advanced analog read function for Arduino, to make using these new analog input capabilities very easy.

CAN Bus

Controller Area Network is a communication used in automobiles. A new library to support Teensy 3.1's CAN controller is planned.

Pinouts

Teensy 3.1 is meant to be a drop-in replacement for Teensy 3.0. Only 1 pin has different functionality.
The reset pin was replaced by A14/DAC, which you can use for true analog output, or as another analog input.

Reset Signal

Teensy 3.0 supported both a Program signal, to reboot into bootloader mode, and a traditional Reset signal, for a conventional reboot that restarts your application.
The Reset signal can be found on a new test point on the bottom side of Teensy 3.1.
