Teensy 2.0¶

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 teensy20 ID for board option in “platformio.ini” (Project Configuration File):

[env:teensy20]
platform = teensy
board = teensy20

You can override default Teensy 2.0 settings per build environment using board_*** option, where *** is a JSON object path from board manifest teensy20.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:teensy20]
platform = teensy
board = teensy20

; change microcontroller
board_build.mcu = atmega32u4

; change MCU frequency
board_build.f_cpu = 16000000L

Uploading¶

Teensy 2.0 supports the next uploading protocols:

• teensy-cli

• teensy-gui

Default protocol is teensy-gui

You can change upload protocol using upload_protocol option:

[env:teensy20]
platform = teensy
board = teensy20

upload_protocol = teensy-gui

Debugging¶

PIO Unified Debugger currently does not support Teensy 2.0 board.
