The IR Object supports all basic functions for infrared communication (based on the RC5 format) in an very 
easy manner. The IR Receiver/Transmitter connected to PORT 2 (RX) und PORT 3 (TX).  
The RC5 data format consists of a device address and a data byte reveived from (or transmitted to) a IR 
remote device.  Even Word sized values are accepted, IR.SEND/GET  will transfer 6 bytes for command and  
6 bytes for address and Toggle.  
 
 

 RC5 FORMAT: 
    13-12-11-10-09-08-07-06-05-04-03-02-01-00   DATA BIT 
     S  S  T a4 a3 a2 a1 a0 c5 c4 c3 c2 c1 c0   RC5 Format 
 
S = Start Bit (auto set/remove by the IR OBject) 
T = Toggle 
a = Address 
c = Command 
 
The IR MODULE expects a receiver connected at port 2 and the 
transmitter connected to port 3 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
IR.INIT 
Activate the Object to get access to its registers for read/write operation. Close other Objects prior to open. 
 
Syntax: OBJECT.instruction 
 

 
IR.GET 
IR.SEND 
Access the I²C bus to read/write a binary value. 
 
Syntax: OBJECT.instruction Address,Data 
 
Address:  Variable or  constant which is send as address 
                at write access (SEND) 
                Variable, the received address is moved to at  read    
                access. Valid for word and byte size. 

                 
Data:      Variable or  constant which is send as data 
                at write access (SEND) 
                Variable, the received data is moved to at  read    
                access. Valid for word and byte size. 
 
Both values (address and data) will be read as 255 if no valid  data frame was received i.e if the receive 
buffer is empty The receive buffer is set to 255 (address and data) if it has been read. 
 
 
IR.OFF 
Close the Object prior to open any other Object. 
 
Syntax: OBJECT.instruction
