==<font color="blue">How to use on STM32 development board</font> ==
==<font color="blue">Product Documentation</font> ==
 
This module is compatible with the ALIENTEK STM32 development board. The specific usage is as follows:
 
*'''Step 1: Download the test program'''
 
# Download the STM32 test program from the [[#Program Download|'''Program Download''']] column
# For a description of the relevant test procedures, please refer to the test program documentation in the package
 
*'''Step 2: Connect the STM32 development board'''
 
# Find the TFTLCD Slot on the development board, connect the module pins and Slot(For example, the module CS pin corresponds to the slot CS pin),
::and then plug them directly into the Slot
 
*'''Step 3: Compile and download the program to the development board'''
 
# Compile and download the program you need to test to the STM32 development board（[https://www.lcdwiki.com/res/PublicFile/STM32_Keil_Use_Illustration_CN.pdf <font color="red"> '''Don't know how to compile and download?'''</font>]）


*'''Step 4: Observe the running of the program'''
