Property reference

	Properties
	Connections
	Device Address
The address pins are used to allow up to 8 individual devices to be connected onto an I2C bus. Sets the state of the pins.
	Channel
Channel selection
	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.
	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	Simulation
	Simulate Comms
Allows the communications to be simulated overriding the value on the panel slider controls.
