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.
