2.operating instructions
<br clear="all">
 
Install the Arduino IDE software on your computer before doing the following
 
a.Connect the 2.8-inch display module to the Arduino development board according to the wiring instructions and power it on (note the development board model)
 
b.Download the 2.8 inch display module package from [[#Driver download|'''Driver download''']] column
 
c.Extract the data package,open the install library folder,you can see the LCDWIKI_GUI,LCDWIKI_KBV and touch screen these three libraries,as shown below:
 
[[file:MAR2808-012.jpg|800x800px]]
 
d.Copy the three libraries:LCDWIKI_GUI,LCDWIKI_KBV,and touch screen to the directory where the Arduino project files are located,
 
The default directory for Arduino project files is "C:\Users\Administrator\Documents\Arduino",You can define it yourself as follows:
 
Open Arduino IDE software,click File->Preferences to define the directory where Arduino project files are located,as shown in the following figure:
 
[[file:MAR2808-017.jpg|800x800px]]
 
e.Open the Example folder in the package, you can see there are 11 test examples, as shown below:
 
[[file:MAR2808-013.jpg|800x800px]]
 
f.Open any test example,eg open "Example_02_clear_screen"
 
g.After opening the "Example_02_clear_screen" test program,click the Tools button to select the board model and port number,as shown in the following figure:
 
[[file:MAR2808-014.jpg|800x800px]]
 
If the development board model selection Mega, you also need to select the processor model, for the 2.8-inch display module,
 
we only select the ATmega2560 processor, as shown below:
 
[[file:MAR2808-015.jpg|800x800px]]
 
h.Click the upload button to compile and download. When "Done Uploading" is displayed,the program has been successfully downloaded to the development board,
 
as shown in the following figure:
 
[[file:MAR2808-016.jpg|800x800px]]
 
i.If the 2.8-inch display module is continuously displayed in black, white, red, green, and blue, the program runs successfully.
 
'''<big>Matters needing attention</big>'''
 
a.The display module uses 8-bit parallel port to transfer data,so the LCDWIKI library also needs to be set to 8-bit mode (since the LCDWIKI library supports
 
both 8-bit and 16-bit modes),the modification method is as follows:
 
Open the file '''LCDWKI_KBV\lcd_mode.h''' and set the '''CONFIG_USE_8BIT_BUS''' macro to 1, as shown below:
 
{{code|1=
//if using 8bit mode,set the below macro definition to 1
//if using 16bit mode,set the below macro definition to 0
#define CONFIG_USE_8BIT_BUS 1
}}'''<big>STM32 platform using instructions</big>'''

(1) Decompress the downloaded test package
(2) Copy the dependent libraries in the Install libraries directory in the package (shown below) to the libraries folder
of the Arduino project directory （ Don't know the Arduino project directory?）
  • Step 4: Compile and download the program to the development board
  1. Open the sample in the Example directory of the package to test, compile and download（ Don't know how to compile and download?）
  • Step 5: Observe the running of the program
  1. After the program is downloaded, run it directly and observe the running status. If it can be displayed normally, the program runs
