Teensy 3.1 / 3.2

Hardware

Platform Teensy: Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port. No special programmer is needed, only a standard USB cable and a PC or Macintosh with a USB port.

Microcontroller MK20DX256
Frequency 72MHz
Flash 256KB
RAM 64KB
Vendor Teensy

Configuration

Please use teensy31 ID for board option in “platformio.ini” (Project Configuration File):

[env:teensy31]
platform = teensy
board = teensy31

You can override default Teensy 3.1 / 3.2 settings per build environment using board_*** option, where *** is a JSON object path from board manifest teensy31.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:teensy31]
platform = teensy
board = teensy31

; change microcontroller
board_build.mcu = mk20dx256

; change MCU frequency
board_build.f_cpu = 72000000L

Uploading

Teensy 3.1 / 3.2 supports the next uploading protocols:

  • teensy-cli
  • teensy-gui
  • jlink

Default protocol is teensy-gui

You can change upload protocol using upload_protocol option:

[env:teensy31]
platform = teensy
board = teensy31

upload_protocol = teensy-gui

Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Teensy 3.1 / 3.2 does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.

Compatible Tools On-board Default
J-LINK   Yes

Frameworks

Name Description
Arduino Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences.
mbed The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community.
