arudino 1.8.13 다운로드
> 1.8.19 는 실패. 이유는 모름
zip파일 압축해제 후 arduino-1.8.13 폴더로 가서 설치
> sudo ./install.sh

teensyduino 다운로드
> 1.8.X 호환버전으로 다운로드 해준다.
next 버튼만 클릭하다 install 누르면 설치된다.
요부분에서만 압축해제한 arduno 폴더로 경로를 지정해주면 된다.

제공하는 rule은 다음과 같다.
# UDEV Rules for Teensy boards, http://www.pjrc.com/teensy/
#
# The latest version of this file may be found at:
# http://www.pjrc.com/teensy/00-teensy.rules
#
# This file must be placed at:
#
# /etc/udev/rules.d/00-teensy.rules (preferred location)
# or
# /lib/udev/rules.d/00-teensy.rules (req'd on some broken systems)
#
# To install, type this command in a terminal:
# sudo cp 00-teensy.rules /etc/udev/rules.d/00-teensy.rules
#
# After this file is installed, physically unplug and reconnect Teensy.

# If you share your linux system with other users, or just don't like the
# idea of write permission for everybody, you can replace MODE:="0666" with
# OWNER:="yourusername" to create the device owned by you, or with
# GROUP:="somegroupname" and mange access using standard unix groups.
#
# ModemManager tends to interfere with USB Serial devices like Teensy.
# Problems manifest as the Arduino Serial Monitor missing some incoming
# data, and "Unable to open /dev/ttyACM0 for reboot request" when
# uploading. If you experience these problems, disable or remove
# ModemManager from your system. If you must use a modem, perhaps
# try disabling the "MM_FILTER_RULE_TTY_ACM_INTERFACE" ModemManager
# rule. Changing ModemManager's filter policy from "strict" to "default"
# may also help. But if you don't use a modem, completely removing
# the troublesome ModemManager is the most effective solution.
00-teensy.rules 파일을 하나 만들어 주고
sudo cp 00-teensy.rules /etc/udev/rules.d/00-teensy.rules
rule을 만들어준다.
위 repo의 내용 긁어서 복붙해도 되고
curl https://raw.githubusercontent.com/micro-ROS/micro_ros_arduino/main/extras/patching_boards/platform_teens.txt > platform.txt
커맨드를 날려도 된다.
