Property reference

	Properties
	Rows
Number of lines of characters the LCD can display.
	Columns
Number of characters the LCD can display on a single line.
	Remap Characters
Used to allow characters to be replaced with alternate characters. Custom characters or characters from the LCD memory map can be used as replacements. Each replacement consumes two bytes of RAM memory and is applied automatically when printing strings.
	Delay Timings
Delay in microseconds used in the display send function. Most displays will work with the default value of 100us. Some displays may need a slightly longer delay, 166us is known to work well.
	Background Color
Simulation only background colour, the actual hardware will have a fixed colour
	Line Color
Simulation only line colour, the actual hardware will have a fixed colour
	Text Color
Simulation only text colour, the actual hardware will have a fixed colour
	Font
Font to use for simulation, the actual hardware will have a inbuilt fixed font.
	Connections
	Channel
Channel selection
	SlaveAddress
	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	SDA
Pin used for SDA (data signal)
	SCL
Pin used for SCL (clock signal)
	Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.
	Simulations
	Console Data
Selects if the console data is automatically generated or not
	Scope Traces
Selects if the component pin connections are automatically generated on the data recorder window or not. Yes: Automatically add the component pins to a group on the data recorder which will reflect the sim data during simultion. No: Do not show the pin signals on the data recorder window.
