Contents |
Action
Sends RC6 remote code.
Syntax
RC6SEND togglebit, address, command
Uses
TIMER1
Remarks
|
Togglebit |
Make the toggle bit 0 or 1 to set the toggle bit |
|
Address |
The RC6 address |
|
Command |
The RC6 command. |
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.
Most audio and video systems are equipped with an infrared remote control.
The RC6 code is a 16-bit word bi-phase coded signal.
The header is 20 bits long including the toggle bits.
Eight system bits hold the system address so that only the right system responds to the code.
Usually, TV sets have the system address 0, VCRs the address 5 and so on. The command sequence is eight bits long, allowing up to 256 different commands per address.
The bits are transmitted in bi-phase code (also known as Manchester code).
