	SetBuffer
Writes data to the RMT buffer
- UINT	Index
Array index, Range: 0 - (BufferSize - 1)
- BOOL	State0
The first state to output
- UINT	Length0
The length of the first output state in divided clock periods
- BOOL	State1
The second state to output
- UINT	Length1
The length of the second output state in divided clock periods
- VOID	Return

	Transmit
Sends out the RMT data buffer.
- VOID	Return

	Initialise
Initialises the RMT module ready for data to be sent or received.
- VOID	Return

Property reference

	Properties
	Mode
Controls if we are transmitting or receiving data
	Pin
Pin to assign the RMT functionality
	Clock Divider
Base Clock speed is 80MHz. Div by 1 = 80MHz Div by 2 = 40MHz Div by 4 = 20MHz Div by 8 = 10MHz
	Mem Block Num
Starting RMT memory block
	Buffer Size
Number of values inside the data buffer, 64 = 1 Block A buffer size of 128 would consume two sequential blocks of memory. If starting at block 1 then you can have a maximum buffer size of 512 consuming all 8 blocks.
	TX Loop Enable
Allows the transmit buffer to be constantly looped.
	TX Carrier Enable
Enables a carrier frequency to be overlaid on the transmitted data
	TX Idle Output
When not transmitting should the Transmit pin be an active output?
	TX Idle Level
Sets the output state when idle.
	RX Filter Enable
Allows the receive data to be filtered.
	RX Idle Threshold
Sets the number of divided clock periods to detect when the receiver is idle. Pulses longer then this period will not be received.
