Action

Retrieves a RC5 infrared code and sub address.

 

 

Syntax

GETRC5(address , command)

 

 

Remarks

 

Use a Siemens infrared receiver SFH506-36 and connect it to port pin 3.2 to use this command.

This statement works together with the INT0 interrupt. See the example below on how to use it.

In version 2.09 the command returns the toggle bit in bit position 5 of the address.

You can clear it  like : address = address AND &B0001_1111

The toggle bit will toggle after each key press of the remote control.

'  connect SFH506-36 IR-receiver to PORT 3.2 (INT0)

'  choose the correct port from the Compiler I2C TAB. Int0 should have P3.2 pin

'  On other chips it may be another pin!
