 ## Docs

-Docs: [maixduino.sipeed.com](https://maixduino.sipeed.com/)
+Docs: [wiki.sipeed.com](https://wiki.sipeed.com/soft/maixduino/zh/index.html)

 ## Install

 Refer install doc: [Install](https://maixduino.sipeed.com/en/get_started/install.html)

+## Installing

-## Other SDK
+### From Board Manager
+
+ 1. [Download and install the Arduino IDE](https://www.arduino.cc/en/Main/Software) (at least version v1.9.8)
+ 2. Start the Arduino IDE
+ 3. Go into Preferences
+ 4. Add ```https://dl.sipeed.com/MAIX/Maixduino/package_Maixduino_k210_index.json``` as an "Additional Board Manager URL"
+ 5. Open the Boards Manager from the Tools -> Board menu and install "Maixduino(K210)"
+ 6. Select your K210 board from the Tools -> Board menu
+
+### From git
+
+ 1. Follow steps from Board Manager section above
+ 2. ```cd <SKETCHBOOK>```, where ```<SKETCHBOOK>``` is your Arduino Sketch folder:
+  * OS X: ```~/Documents/Arduino```
+  * Linux: ```~/Arduino```
+  * Windows: ```~/Documents/Arduino```
+ 3. Create a folder named ```hardware```, if it does not exist, and change directories to it
+ 4. Clone this repo: ```git clone https://github.com/Sipeed/Maixduino Maixduino/k210```
+ 5. Restart the Arduino IDE
+
+### Firmware flashing
+The firmware of the K210 devices is updated with a Python-based [kflash](https://github.com/sipeed/kflash.py) cross-platform tool.
+Follow ```kflash``` github page on installation instruction.
+
+
+###### Change board settings in Tools section on the top of Arduino IDE
+
+ 1. Board: The same as your dev board
+ 2. Burn Toolfirmware: leave default, for Maix Go Kit - ```open-ec```
+ 3. Burn Baudrate: Decrease it if download fails
+ 4. Port: Serial port, e.g. ```/dev/ttyUSB0```
+ 5. Programmer: ```k-flash```
+
+## Credits
+
+This core is based on and compatible with the [Sipeed Maixduino Core](https://github.com/sipeed/Maixduino)

-If you want to code by scripts, refer to our [MaixPy](https://maixpy.sipeed.com)

per1234	86acd72c3d	Use optimal bundled library names When multiple libraries contain files matching an #include directive in the program, the Arduino build system must pick one to use for compilation. Multiple factors are used in order to make an intelligent determination of which library is best. In order to enhance this determination, the closeness of match between the library.properties name value and the filename in the #include directive is being added as one of those factors. This new factor is referred to as "Library Name Priority". Unfortunately, this change can result in platform bundled libraries which had previously been correctly correctly chosen no longer being given priority over their equivalent standalone libraries, which may be incompatible or not optimized for the platform's boards. This priority inversion only occurs when all the following conditions are true: - There is a standalone library installed which provides a header filename collision. - The platform bundled library is architecture optimized (e.g., architectures=esp32). - The standalone library is architecture compatible (architectures=*). - The standalone library has equal "Folder Name Priority". - The standalone library has better "Library Name Priority" (e.g., name=SD vs name=SD(ESP32) for a library with primary header file SD.h. The fix is to simply give the platform bundled library a perfect "Library Name Priority". Some platform bundled libraries were given a modified name as a workaround to a bug in the Arduino IDE's Library Manager which caused Library Manager to always show the library as updatable under specific circumstances. That bug was fixed in Arduino IDE 1.8.6, ~3 years ago.	2021-05-30 13:11:35 -07:00
