Working Principle

The Intelligent TFT-LCD Module communicates with the Customer’s MCU / CPU / FPGA / PLC via Commands (JSON command and HEX Code), and then the MCU would control its connected equipment to work according to the received
commands.

Service：

Replace by a brand-new Unconditionally

2. customizable service.
a. Customize TFT-LCD Module according to the customer’s requirement.
b. Develop the customization function.
c. Optional resolution
d. Optional luminance

Optional UART interface type (RS232/RS485/TTL)
Optional touch control type (resistive/capacitive/non-touch)

FAQ:

Question 1: What is the communication protocol for the STONE products?
Answer: The communication protocol is a customized command set.
For example:
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
Description:
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

Question 2:Can we use CANBUS/MODBUS protocol to communicate with the STONE product?
Answer: No. The CANBUS/MODBUS protocol is not supported for now.

Question 3: Can we use Arduino as the controller of the STONE product?
Answer: 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.

Question 4: Can we use Raspberry Pi as the controller of the STONE product?
Answer: 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.
