The module hardware supports 8-bit and 16-bit parallel port data bus mode switching (shown in red box in Picture 2), as follows:

Solder R16 with 0Ω resistor or short circuit directly, and disconnect R8: Select 16-bit parallel port data bus mode, use DB0~DB15 data pins(default)

Solder R8 with 0Ω resistor or short circuit directly, and disconnect R16: Select 8-bit parallel port data bus mode, use DB0~DB7 data pins

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 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.
