Introduction
1.6 Operation Processing
Only 3 steps to operate our TFT-LCD Module:
1) Build a new GUI project by STONE GUI Designer Software.
2) Connect with customer’s MCU through RS232,RS422,RS485,TTL directly, Plug & Play.
3) Write a simple program for MCU to control the TFT-LCD Module via Instruction Sets.
The communication protocol is built with 2 parts:
1）Initiative Instruction - JSON Code (MCUTFT-LCD Module)
Frame header instruction code widget type widget name data Frame tail
ST< {"cmd_code":"set_value","type":"label","widget":"label2","value":5} >ET
2）Passive Instruction - HEX Code (TFT-LCD ModuleMCU)

Note A: 1. Adopting the 8 Pin 2mm spacing socket. Model Code: A2008WR-S-8P.
2. Direction of the signal was defined with TFT-LCD Module;
“I” refers to the signal from the user’s MCU transmitted to the TFT-LCD Module.
“O” refers to the signal from the TFT-LCD Module transmitted to the user’s MCU.
3. Pins with the same definition are connected together in the module inside.
4. RS232, TTL, RS422, RS485, port can be default which need to point out in the order.
