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.

Frequently asked questions:
1. What is the communication protocol for the STONE products?
A: The communication protocol is a customized command set.
Setting the number of input data bits is 4 bit, click the "Data entering" button to input "1234 ", click "OK", and the UART returns to the command:
A5 5A 06 83 00 20 01 04 D2
A5 5A: Frame head
06: command byte length, 83 00 20 01 04 D2 total 6 bytes (without frame header)
83: Read variable register command
00 20: Variable address, set in control properties
01: Data word length, 04 D2 total 1-word length
04 D2: Data content, 1234 hexadecimal data
2. Can we use CANBUS/MODBUS protocol to communicate with the STONE product?
A: No. The CANBUS/MODBUS protocol is not supported for now.
3. Can we use Arduino as the controller of the STONE products?
A: Yes. Arduino has the TTL signal pin. You can directly use the STONE display with the TTL interface (please contact our staff to confirm the interface type). Or you can use the MAX3323 chip to converter the TTL signal to the RS232 signal.
You can check the link to get the specific steps:
4. Can we use Raspberry Pi as the controller of the STONE products?
A: Yes. Raspberry Pi provides build-in/mini UART.
They are implemented using different hardware blocks, so they have slightly different characteristics. However, both are 3.3V devices, which means extra care must be taken when connecting up to an RS232 or other systems that utilize different voltage levels.
