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.
