Larduino UNO

The domestic LGT8F328P chip Aruino UNO learning board designed by Lichuang EDA is used. The attachment is the arduino hardware support package of the chip.

The chip needs to be programmed with the original programmer to program the BootLoader. Friends who do not have the original programmer can ask the seller to help program the BootLoader when purchasing the chip.
BootLoader searches for optiboot_lgt8f328p.hex in the decompressed file of the attached hardware support package.
Use the original Arduino UNO to flash the BootLoader for the LGT8F328 chip. See the Larduino_ISP_SHIELD open source project.

Welded board

Below is a brief explanation of how to use it.
Step one: Install the CH340 serial port driver. (Friends who have already installed the CH340 driver when playing other microcontrollers can skip the first step)
Open the folder where the attachment is decompressed and run the ch341ser.exe driver installation program.

Click directly to install.

The serial port driver is pre-installed successfully.

Step 2: Add hardware support package.

Open the preferences of Arduino IDE (Arduino IDE download link: https://downloads.arduino.cc/arduino-1.8.12-windows.exe )

Determine project folder location

Copy the three folders in the unzipped hardware support package to the Arduino folder in the project folder location directory

Click Yes to confirm merging the libraries folder

Step 3: Restart Arduino IDE and download the sample program

Close Arduino IDE

Restart the Arduino IDE and click Tools -> Development Board Select LGT8F328P-LQFP32 MiniEVB

Connect the Arduino UNO domestic chip compatible board to the computer and select the serial port

Download the experimental program. In Arduino, downloading the program from the computer to the board is called uploading.

The experimental results of the project are the same as those of the foreign original Arduino UNO.
