Arduino and Teensy libraries

Installation of Arduino and Teensy support

This is probably not needed if you intend to use MS Visual Studio.

Arduino (version 2.xx)

• Install the newest Arduino - see https://www.arduino.cc/en/software.

Add Teensy board support

• Add the Teensy hardware support - see https://www.pjrc.com/teensy/td_download.html, including

• Add https://www.pjrc.com/teensy/package_teensy_index.json to the file->preferences

• In the boards manager (Tools->Boards->Boards manager), search for Teensy and install support for Teensy boards.

Add libraries

• In the Library manager (Tools->Manage libraries), search for "MPU9250_asukiaaa" and "Adafruit GFX library" and install both, including dependencies. These are used to interface the IMU and support for the small display.

Board select

Select the Teensy 4.1 board (tool->board->Teensy->4.1).

Select the port the robot is connected to - it is easier to connect it first.

Arduino command line interface

See https://docs.arduino.cc/arduino-cli/

Install Arduino CLI

Get the install script and let it install arduino-cli into the directory ~/bin. It will detect the download platform and install an appropriate version.

cd
curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh
cd bin
pwd

Add this directory to the PATH.

nano ~/.bashrc

Add at the end (assuming your login name is local)

export PATH=$PATH:/home/local/bin

Add Teensy support

Make a configuration file (in a hidden file called ~/.arduino15/arduino-cli.yaml).

arduino-cli config init

Copy the URL for Teensyduino https://www.pjrc.com/teensy/package_teensy_index.json and add it to the configuration file.

nano ~/.arduino15/arduino-cli.yaml

Make it look like this:

board_manager:
   additional_urls: ["https://www.pjrc.com/teensy/package_teensy_index.json"]

After this, update the index

arduino-cli core update-index

Teensy support

Find the install name of the board type to install

$ arduino-cli core search teensy
ID         Version Name
teensy:avr 1.59.0  Teensy (for Arduino IDE 2.0.4 or later)

Then, install and configure the Teensy support

arduino-cli core install teensy:avr

Install libraries

Robobot need (especially) these libraries.

• Adafruit GFX Library
• MPU9250_asukiaaa

If the exact name is not known, then search, e.g.:

arduino-cli lib search name:"Adafruit GFX Library"

Install

arduino-cli lib install "Adafruit GFX Library"
arduino-cli lib install "MPU9250_asukiaaa"
