STVI035WT-01 TFT display Description:


STONE provides customers with Intelligent HMI solutions. The intelligent TFT LCD module with a Cortex-M4 32-bit CPU can be controlled by any MCU via simple Hex Instruction through the UART port.

STVI035WT-01 TFT LCD module consists of a CPU, TFT drives, flash memory, UART port, power supply, etc. STONE also provides a basic control program and powerful design software (STONE TOOL Box). You can use it to set various functions on the graphical user interface, such as text, figures, curve, image switching, keyboard, progress bar, the slider, dial-up, clock and touch button, data storage, the USB download, video, and audio.

It is very easy for engineers to develop the TFT-LCD color user interface and touch control functions, which can reduce a lot of development time and cost.

STONE TOOL Box(GUI Design software):


STONE TOOLBox (software)


1. Create a graphic user interface (GUI). We will provide you a very powerful and simple GUI design software—STONE TOOL Box. You can use it to create your own interface by using any .jpg/.bmp format image. 

2. Assign the different variable memory addresses for the different function block-like data display, text display or variable icons, to make sure the variable value can be stored and assigned.
3. Connect your display with your controller via the RS232/RS485/TTL interface.
4. Program your controller with any language to send the hex command sets to the display, read/write the variable memory or register values.




STONE LCD display module Application sample:


For example: display the English and number "VIEW 123"
The UART sends command: A5 5A 0A 82 01 40 56 49 45 57 31 32 33 




A5 5A: Frame head 
0A: command byte length, 82 01 40 56 49 45 57 31 32 33 is 10 bytes (without frame header) 
82: write variable register command 
01 40: Variable address, set in control properties 
56 49 45 57 31 32 33: Data content, ASCII code for "VIEW 123"
