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

Q: What kind of interface does STONE use to connect with the control device?
A: All STONE product is using UART serial interface (RS232/RS485/TTL) to connect with the control device.
The other interface such as HDMI, SPI, RGB, etc. is not available for the STONE products right now.
A: Yes. The STVA series product is a high luminance model (1000 cd) and sunlight readable.
A: Yes. We have plastic/metal/IP65 (water, dust, oil proof) bezel available as accessories.
A: We have resistive touch, capacitive touch, and non-touchscreen display available.
Sample for developing:
For example: Show integer "1234 ", the UART returns the command:
A5 5A 05 82 00 20 04 D2
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
