Normal RC5 code uses 2 leading bits with the value '1'. After that the toggle bit follows.

With extended RC5, the second bit is used to select the bank. When you make it 1 (the default and normal RC5) the RC5 code is compatible. When you make it 0, you select bank 0 and thus use extended RC5 code.

<span style="font-family: Arial;">&nbsp;</span>

The resistor must be connected to the OC1A pin. In the example a 2313 micro was used. This micro has pin portB.3 connected to OC1A.

Look in a data sheet for the proper pin when used with a different chip.

<span style="font-family: Arial;">&nbsp;</span>

Most audio and video systems are equipped with an infra-red remote control.

The RC5 code is a 14-bit word bi-phase coded signal.

The two first bits are start bits, always having the value 1.

The next bit is a control bit or toggle bit, which is inverted every time a button is pressed on the remote control transmitter.

Five system bits hold the system address so that only the right system responds to the code.

<span style="font-family: Arial;">&nbsp;</span>

Usually, TV sets have the system address 0, VCRs the address 5 and so on. The command sequence is six bits long, allowing up to 64 different commands per address.

<span style="font-family: Arial;">&nbsp;</span>

The bits are transmitted in bi-phase code (also known as Manchester code).

An IR booster circuit is shown below:
