Property reference

	Properties
	I2C Config
	LCD Address
	RGB Address
	Alt RGB Address
	Channel
Channel selection
	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	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.

	Simulate Comms
Used to drive the comms durig simulation which can be used to: Data Recorder waveform generation Console Logging Data Injector to redirect the data e.g. to a SCADA slave connected to the physical hardware
	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.
	Console Data
Selects if the console data is automatically generated or not
	API
Specifies the injector component on the panel to interact with to provide comms simulation.
