	Note. Float type value might rounded or truncated due to hex-dec conversion		Note. Float type value might rounded or truncated due to hex-dec conversion

			=== How to hide an element in page? ===
			<u>Real Time Properties Control</u>

			* Enable VP is can be use to hide an element in page
			* Enable VP is none by default (element operate normally)
			* It can assign a VP address (VP_N16, VP_N32, VP_N64) to it as its Enable control register
			* The VP value set to 1 as enable at power-on.
			* It can be disabled (hidden) by a zero value

			=== How to display Chinese Char? ===

			* Smart LCD support GB2312, GBK, BIG5
			* GB2312 support the most command 6763 simplified Chinese
			* Select a Chinese Font Char set in the String ElementConfig a VP_STR with it
			* Send a GB code string to the VP_STR to display it on screen

			Note. It can generate custom font in SGTools (Menu ⇒ Tools ⇒ Font Setting ⇒ Font Config <2>)

			== Communications ==

			=== How to config the terminal buadrate? ===
			<u>By Project setting</u>

			* The terminal baudrate can be config in the SGTools (Menu ⇒ Tools ⇒ Project Setting)

			[[File:SGT Project Baud Rate.png\|223x223px]]

			* default is115200 baud per second

			<u>By Command</u>

			* It is also possible to change the baudrate by using command.
			* Use a E0 command to set sys config (AA E0 55 AA 5A A5 07 83 00 CC 33 C3 3C)
			* Baud rate will back to project setting after next power on

			=== How to resolve communication issue? ===
			<u>Physical Connections</u>

			* Check the terminal connections cable
			* Ensure the GND is connection
			* Confirm the cross wiring (Tx to Rx )

			{\|
			\|Smart LCD TX ⇒ PC Rx
			\|-
			\|Smart LCD Rx ⇐ PC Tx
			\|-
			\|Smart LCD RTS ⇒ PC CTS
			\|}
			<u>Signal Levels</u>

			* Check the terminal signal of the Smart LCD
			* There are three kind of Smart LCD terminal (depends on model) UART (3.3V) / RS-232C (±12V) / RS-485 (3.3V)
			* The host and the Smart LCD must be have the same signal levels
			* Only Smart LCD with RS-232C can interface to PC RS-232C signal(±12V)

			<u>Byte Packet Config</u>

			* Check the baud rate (115200 by default)
			* Check the no. of bit, parity and stop bit (8N1 by default)
			* All the command are in hex/binary (NOT ASCII)

			=== What is the function of terminal RTS signal? ===
			<u>RTS signal</u>

			* RTS is an output signal of the Smart LCD, working like a busy signal
			* It will be set, while the Smart LCD input buffer full When RTS set, host should stop sending data/command to prevent data/command lost
			* As Smart LCD is having 32kbyte (various by model) input buffer
			* In most of the case, it may not necessary to use RTS signal
