Teensy 3.1 / 3.2¶

System¶

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.

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.

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.
