Interface Definition
The red box in the above figure is the 8-bit/16-bit data bus mode switch, which is described as follows: - Solder R5 with 0Ω resistor or short circuit directly, and disconnect R4: select 16-bit data bus mode (default), use DB0~DB15 data pin
- Solder R4 with 0Ω resistor or short circuit directly, and disconnect R5: select 8-bit data bus mode, use DB8~DB15 data pin

How to use on STM32 development boardThis 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 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( Don't know how to compile and download?)
- Step 4: Observe the running of the program
- After the program is finished, observe the running status of the program. If it can be displayed normally, the program runs successfully.
