Arduino Core for Seeed i.MX RT Series Boards

This repository contains the Arduino BSP for Seeed i.MX RT Series:

Arch Mix

Add the imxrt-based board to the Arduino IDE

Step 1. Download the latest Arduino IDE

You need a Arduino IDE that after version 1.6.4, please download one if there's no Arduino IDE in your computer.

Step 2. Setting your Arduino IDE

Open your Arudino IDE, click on File > Preferences, and copy below url to Additional Boards Manager URLs

https://raw.githubusercontent.com/Seeed-Studio/Seeed_Platform/master/package_seeeduino_boards_index.json

Build ArduinoCore-imxrt with cmake

git clone https://github.com/seeed-Studio/ArduinoCore-imxrt 
cd ArduinoCore-imxrt 
mkdir -p examples/Blink
touch  examples/Blink/Blink.ino  #You can write your own arduino code here
mkdir build && cd build
# Make sure you cross-compile the toolchain with the correct path
cmake .. -DPROJ=Blink -DTOOLCHAIN=~/gcc-arm-none-eabi/bin -DBOARD=arch_mix -DCPU=MIMXRT1062DVL6B

Add the imxrt-based board to the platformIO

Arduincore-imxrt supports not only ArduinoIDE development, but also PlatformIO platform. PlatformIO is an open source ecosystem for IoT development. Currently, you need to manually configure ArduinoCore-imxrt to the platformIO platform.

step 1. Install platformIO IDE

you can follow this guide.

step 2. Download the following resources

platform-nxpimxrt
ArduinoCore-imxrt
flash tool

Download the version according to your system.
- Windows
- Linux
- Mac OS

step 3. Extract the corresponding file to the corresponding directory

Find the installation directory of platformIO IDE.

Usually its will be in the user directory, which name ".platformio"
Extract the platform-imxrt to [user]/.platformio/platforms/
Extract the ArduinoCore-imxrt to [user]/.platformio/packages/
Extract the flash tool to [user]/.platformio/packages/

step 4. Create the platformIO project

Develop using the SDK

You can develop your applications using the SDK Whether you're on platform IDE or Arduino IDE.
