1. The hardware of the module supports switching between resistance touch screen and
- capacitive touch screen (as shown in the dotted line box in Picture 2 above), as follows:
- Use resistance touch screen: solder the components in the dotted line box of RTOUCH,
- and do not need to weld the components in the dotted line box of CTOUCH;
- Use capacitive touch screen: solder the components in the dotted line box of CTOUCH,
- and do not need to weld the components in the dotted line box of RTOUCH;
2. The hardware of this module only supports 16 bit mode

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.
