LED Matrix (Serial) component

LED Matrix component designed to work using a single data and clock pin. Each LED on the display can be controlled in a chain by setting the data appropriatley and then generating the appropriate amount of clock pulses.

Macro reference

ClearLEDs

	ClearLEDs
Sets all of the LEDs in the matrix to the off state.
- VOID	Return

DisplayString

	DisplayString
Prints an ASCII string onto the LED Matrix a column at a time.
- STRING	Data
Data string to display on the LEDs
- UINT	Animation_Delay
Delay in milliseconds between writing to the next column
- BYTE	Leadout
Allows the text to scroll completely off the display before returning 0=No, 1=Yes
- BYTE	Add_Spaces
Add spaces between each ASCII character 0=No, 1=Yes
- VOID	Return

StrobeHigh

	StrobeHigh
Sets the strobe pin high. Strobing controls the LED brightness and does not apply to simulation.
- VOID	Return

StrobeLow

	StrobeLow
Sets the strobe pin low. Strobing controls the LED brightness and does not apply to simulation.
- VOID	Return

WriteColumn

	WriteColumn
Allows a single column of data to be inserted, Acts to shift the rest of the columns across by one.
- BYTE	Data
Data to display on the column of LEDs
- BYTE	Return

Property reference

	Properties
	LED Type
Active high outputs a logic 1 to set the LED and logic 0 to clear the LED. Active low outputs a logic 0 to set the LED and logic 1 to clear the LED
	Row Count
Number of LED rows
	Column Count
Number of LED columns
	LED Count
Total number of LEDs in the component
	Flip Display
Allows the column and text data sent to the display to be flipped
	Connections
	Data In
Data In pin which is used to pass the input LED value
	Data Out
Data Out Pin - Optional and used to collect the data as it leaves the last buffer
	Clock
Clock pin used to clock the external buffer IC's
	Strobe
Strobe pin used to control the master display state, strobed at high speed using PWM to set the brightness.
	Reset
Reset pin used to clear all of the states in the external buffer IC's
	Colours
	On Color
Simulated colour of the LEDs when switched On
	Off Color
Simulated colour of the LEDs when switched Off
	Simulation
	Row Spacing
Simulation row spacing
	Column Spacing
Simulation column spacing
	Width
Simulation LED width
	Height
Simulated LED height
	Depth
Simulated LED Depth (3D environments only)
	LED Shape
Simulated LED basic shape
	Redraw LEDs
Simulated LED redraw option, display will not be updated until the redraw is set to Yes. Automatically revers back to No after the refresh has been performed.
