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
- 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)
- You can also download the standard routines that come with the punctual atomic STM32 development board
- 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 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
- 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
