Set Learnable Ir Command Codes - Zektor CVS4 User Manual

CVS4 Command Reference (Cont'd)
2) This command gives the controller full access to the CVS4's IR sensor and Zektor's IIR™
algorithm. This is a very reliable way of adding IR control to any project. The IR codes generated
by Zektor's IIR™ algorithm are immune to timing differences between universal remote control
manufacturers and to the timing errors associated with condition of the remote control's battery.
Note 1: The Zektor's IIR™ algorithm works with any remote control code that is time modulated.
This is pretty much every type of IR code except the Phillips RC-5, and RC-6 codes.
Note 2: Because very few controllers can handle a 72 bit decimal value, and in an effort to keep
the size of the IR code small, this command sends the 72 bit IR code as an 18 digit hexadecimal
value.

IR
Response String:
=IR ircode
Where:
ircode = 18 hex digits (0-9, A-F), representing the most recent IR code received.
This command returns a single digit '0' if there are no IR codes waiting to be read.

Set Learnable IR Command Codes

This command is used to set, or retrieve, the current IR codes associated with the learnable IR
commands. This is useful for "cloning" the IR codes learned in one CVS4 into another CVS4.

IRC ircmd,?
IRC ?
Response String:
=IRC ircmd,ircode
Where:
ircmd = IR command number being set / retrieved (See Table).
ircode = 72 bit IR code (See: "IR" command).
