   Arduino IDE introduced official support for adding third party boards (like the OSOYOO LGT-Nano) to the new Board Manager. This addition is great news, because it allows users to quickly add new boards with the click of a button. Previously the addition of new boards required a cumbersome manual installation process, or in certain cases, the download of a completely separate version of the IDE with the new boards added.

  The new Board Manager solves those issues. We can now add new boards just as easily using officially supported methods. Let’s get started.

Note: For LGT-Nano Board V1.0, you cannot directly connect it to your computer or cell phone with USB-C to USB-C cable, you need to use OTG cable to perform related operations.

The first thing you will need to do is to download and install

Arduino IDE (Recommend  Legacy IDE 1.8.x). 

Make sure you have the CH340 driver installed before proceeding

There are two method to install OSOYOO boards as follows.

Method 1: Automatic Installation

step 1. Open arduino IDE and navigate to the Preferences menu, a dialog will pop up just like the one shown below.

In File->Preferences, Settings tab,

We will be adding a URL to the new Additional Boards Manager URLs option. The list of URLs is comma separated, and you will only have to add each URL once. New OSOYOO boards and updates to existing boards will automatically be picked up by the Board Manager each time it is opened. The URLs point to index files that the Board Manager uses to build the list of available & installed boards.

To find the most up to date list of URLs you can add, you can visit the list of third party board URLs on the Arduino IDE wiki. We will only need to add one URL to the IDE in this example, but you can add multiple URLS by separating them with commas. Copy and paste the link below into the Additional Boards Manager URLs option in the Arduino IDE preferences.

Enter

https://raw.githubusercontent.com/DavidGuo-CS/OSOYOO_Arduino/main/package_osoyoo_boards_index.json

as an Additional Boards Manager URL.

If the above website does not open, try another one：

https://gitee.com/davidgmx/OSOYOO_Arduino/raw/main/package_osoyoo_boards_index_zh.json

or

https://osoyoo.com/driver/lgt_driver/package_osoyoo_boards_index.json

Step2.  Installing Boards

Now that you have added the appropriate URLs to the Arduino IDE preferences,  open Tools->Board: ->Boards Manager

Step3. Click on the search menu and  type osoyoo,then you will find OSOYOO AVR Compatible Boards and install it.

(You will then be able to select and install the boards supplied by the URLs added to the prefrences. In the example below, we are installing support for OSOYOO AVR Compatible Boards, but the same applies to all boards installed with the Board Manager.)

If you can not find the OSOYOO AVR Compatible Boards in the Board Manager, try another one URL link as an Additional Boards Manager URL.

Step 4.  Reopen the Arduino IDE to ensure that the boards are properly installed. You should now be able to select the new boards listed in the Tools->Board menu. Choose OSOYOO boards from the list

Method 2 : Manual installation

Step 1. Directly download the latest software support package

Step 2. Open arduino file location , then unzip and copy the file of osoyoo_arduino-1.0.0 to …\arduino\hardware\ as follows.

Step 3. Open the file of osoyoo_arduino-1.0.0 and

change the file name osoyoo_arduino-1.0.0 to avr to see the boards.txt and platform.txt files

Step 4. Re-open the Arduino IDE application,   click Tools and choose the  Board:OSOYOO LGT Nano

OSOYOO AVR Compatible Boards is a 3rd party hardware support package for the LGT8F core based arduino boards. The backend of the HSP is fork from offical arduino distribution. We have try to keep all the standard features compatible with arduino world. So feel free to resuse all of the libraries which designed for arduino platform.

Microcontroller based on LGT8F, e.g LGT8F328P has more advanced features which not covered in standard arduino implementation. so there are also many new features merged to this 3rd party package. Important update and new features as following:

Pin Different

LGT8F328P DataSheet

Hardware Reference design

pin_diff

Bootloader

The LGT8F328P bootloader is based on optiboot. Source can be found inside the bootloader directory
