sub function Man_Receive(dim byreferror as byte) as byte

A byte read from the incoming signal.

The function extracts one byte from incoming signal.

Parameters : 

- 

error:

error flag. If signal format does not match the expected, the error flag 

will be set to non-zero. 

To use this function, the user must prepare the MCU for receiving. See

dim data, error as byte
...

data = 0
error = 0

data = Man_Receive(&error)

if (error <> 0) then
' error handling 
end if

sub procedure Man_Send_Init()

Nothing.

Global variables : 

- 

MANRXPIN

: Receive line 

- 

MANRXPIN_Direction

: Direction of the receive pin 

must be defined before using this function. 

' Initialize Transmitter:
dim MANTXPIN as sbit at PINB.B1
dim MANTXPIN_Direction as sbit at DDRB.B1
