Introduction
1.6 Operation Processing
Only 3 steps to operate our TFT-LCD Module:
⚫Build a new project by STONE GUI Design Software.
⚫Connect with customer’s MCU through RS232,RS422,RS485,TTL directly, Plug & Play.
⚫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)
