Property reference

	Properties
	Channel
Channel selection
	SDA
Pin used for SDA (data signal)
	SCL
Pin used for SCL (clock signal)
	SDA Remap Pin

	SCL Remap Pin

	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.
	Simulation
	Simulation Comms

	Simulation
	Min. Temp.
Minimum termperature that can be set or displayed on the thermometer slider.
	Max. Temp.
Maximum termperature that can be set or displayed on the thermometer slider.
	Scale divisions
Number of numbered divisions shown on the thermometer scale.
	I2C Data
Set whether the I2C data is displayed as decimal or hexadecimal numbers.
