# Arduino Core for Seeed i.MX RT Series Boards

This repository contains the Arduino BSP for Seeed i.MX RT Series:
- [Arch Mix](https://www.seeedstudio.com/Arch-Mix-p-2901.html)
## 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.

[![](https://raw.githubusercontent.com/SeeedDocument/Seeeduino_Stalker_V3_1/master/images/Download_IDE.png)](https://www.arduino.cc/en/Main/Software)

### 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](https://platformio.org/) 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](https://docs.platformio.org/en/latest/ide/pioide.html).

### step 2. Download the following resources

- [platform-nxpimxrt](https://github.com/Seeed-Studio/platform-nxpimxrt)

- [ArduinoCore-imxrt](https://github.com/Seeed-Studio/ArduinoCore-imxrt)

- [flash tool](https://github.com/Seeed-Studio/BOSSA)

  Download the version according to your system.

  - [Windows](https://github.com/Seeed-Studio/BOSSA/releases/download/1.9.1-seeeduino/bossac-1.9.1-seeeduino-windows.tar.bz2)
  - [Linux](https://github.com/Seeed-Studio/BOSSA/releases/download/1.9.1-seeeduino/bossac-1.9.1-seeeduino-linux.tar.gz)

  - [Mac OS](https://github.com/Seeed-Studio/BOSSA/releases/download/1.9.1-seeeduino/bossac-1.9.1-seeeduino-drawin.tar.gz)

### 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.
