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)
Frame header CMD LEN DATA Frame tail CRC16
53 54 3C 10 62 00 09 6C 61 62 65 6C 3F A1 47 AE 3E 45 54 6C 8B
