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 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.
