12.1 inch TFT LCD Screen Description:

 

STONE provides an Intelligent HMI solution. The intelligent TFT LCD screen display set since it is embedded with a Cortex-M4 32-bit CPU processor and LCD driver, so you don’t have to re-design the LCD driver anymore. The pictures or audio/video files can be stored in the memory, so you can use any simple MCU to control the display by sending hex commands through the UART port.

The TFT LCD screen display 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 screen 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)

 

-- Free and easy to use STONE TOOL Box software

-- property value components that can be allocated at run time

-- Drag-and-drop components for GUI design and interaction

-- built-in debugger for HMI project emulation

 

 

Sample for the STONE TFT LCD screen developing:

 

1) Design your own interface with the TOOL software with .jpg files and generate a project file.
2) Download the project file into the STONE TFT screen display by USB, then connect the display with your MCU or other control devices by UART interface (RS232/RS485/TTL).
3) Program your MCU to communicate with the display by the customized command sets.
For example:  Show integer "1234 ", the UART returns the command: 


A5 5A 05 82 00 20 04 D2 


Description: 


A5 5A: Frame head 
05: command byte length, 83 00 20 04 D2 total 5 bytes (without frame header) 
83: write variable register command 
00 20: Variable address, setting in control properties
04 D2: Data content, 1234 hexadecimal data
