3.Ambient temperature when the backlight is lit (reference value)
4.Any Stresses exceeding the Absolute Maximum Ratings may cause substantial damage to the device. Functional
operation of this device at other conditions beyond those listed in the specification is not implied and prolonged
exposure to extreme conditions may affect device reliability.

Protocol V6.12
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):
