- TML files, Picture files, ICON files are stored inside FLASH memory area.
They are preloaded to HMT040ATA-D 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

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.

2.2 Packet Timeout
TOPWAY SmartLCD support Timeout setting, which can be defined in editor project setting.
Timeout options: None, 1s, 2s, 3s, 5s, 10s, 20s. If timeout, The incomplete Packet will be discarded.
2.3 Packet Acknowledgment
Packet Acknowledgment is two byte in ASCII (module  host):
