How to use on STM32 development board

This module is compatible with the ALIENTEK STM32 development board. The specific usage is as follows:

  • Step 1: Download the test program
  1. Download the STM32 Mini development board IO emulation or other development board FSMC test program from the Program Download column (only these programs support the STM32 development board in-line)
  2. 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
  1. Find the TFTLCD interface on the development board, connect the module pins and interfaces, and then plug them directly into
the interface(for the connection method, please refer to the instructions of the ALIENTEK STM32 development board)
  • Step 3: Compile and download the program to the development board
  1. Compile and download the program you need to test to the STM32 development board（ Don't know how to compile and download?）
  • Step 4: Observe the running of the program
  1. After the program is finished, observe the running status of the program. If it can be displayed normally, the program runs successfully.
