Initialise

	Initialise
Initialises the I2C peripheral ready for communications.
- VOID	Return

ReadJoystick

	ReadJoystick
Reads the joystick Returns the direction as a bit field. 1 = Down / 2 = Right / 4 = Up / 8 = Click / 16 = Left

Property reference

	Properties
	I2C
	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
	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
