- TML files, Picture files, ICON files are stored inside FLASH memory area.

They are preloaded to HMT043ATA-7C for stand alone interface use.

- Those files are preloaded via USB interface as an USB drive.

- All the interface flow and the touch response are based on the preloaded TML files

- VP variables memory is inside RAM area,

it provides real time access via UART by the HOST or display onto the TFT by TML file.

- Custom Memories are inside FLASH memory area

It can be accessed via UART interface by the HOST.

- Control and Draw Engine executes HOST commands and response respectively

- It also reports the real time Touch Key number to the HOST

SMART LCD Command Manual

Protocol V5.04

1 Basic Specifications

TOPWAY Smart LCD serial command is for real-time control and access. Host machine get the data

which input through the Smart LCD interface or provide the data for display.

1.1 Hardware connection

Smart LCD serial UART interface are mainly base on RS232-C standard, by default, config as 8N1

115200bps.

2 Command Structure

2.1 Communication Packet Structure

Commands and Response Packet should be format as follow (host  module):

Seq
