ABSTRACT:
A transmitter that is programmable to transmit one or more identification or device codes, using one or more transmission formats, at one or more transmission frequencies to control one or more respective devices. In one embodiment, the transmitter includes a controller and memory for storing transmission values and corresponding transmission frequencies, where the transmission values may include multiple device codes and transmission formats. A subset of the transmission values and corresponding transmission frequencies stored in the memory are assigned to or associated with one or more actuation switches upon matching the transmission values in a sampled signal to a set of transmission values stored in memory. In one embodiment, the transmission values may correspond to either a fixed-code transmission format or a rolling-code transmission format.
