Introduction
1.6 Operation Processing
Only
3 steps
to use our TFT-LCD Module:
1. Design a group of Beautiful “Graphical User Interface”. (Ref. Picture 1.4-1)
2. Connect with customer’s MCU through RS232, RS485 or TTL level directly. Plug and play.
3. Write a simple program for MCU to control the TFT-LCD Module via Command. (HEX Code).
That’s all.
The TFT LCD module (VGUS serial port screen) serial port command frame is composed
of 5 data blocks, shown as the table 1-1.6. All serial port commands or data are represented
with hex format. The data transfer in MSB manner. E.g. for 0x1234, first send 0x12 and then
send 0x34.
