This repository contains the Arduino BSP for Seeed i.MX RT Series:
FYI here
You need a Arduino IDE that after version 1.6.4, please download one if there's no Arduino IDE in your computer.
Open your Arudino IDE, click on File > Preferences, and copy below url to Additional Boards Manager URLs
https://files.seeedstudio.com/arduino/package_seeeduino_boards_index.json
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=MIMXRT1052DVL6B
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.
you can follow this guide.
-
Download the version according to your system.
-
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/
You can develop your applications using the SDK Whether you're on platform IDE or Arduino IDE.
