A programmable universal remote control for controlling a plurality of electronic devices is provided, including a microprocessor (10), a keyboard matrix (20) coupled to the microprocessor (10) for inputting information into the microprocessor (10) and an output circuit (40) coupled to the microprocessor (10). The microprocessor (10) outputs driving signals to the output circuit (40) for outputting remote control command signals for controlling an electronic device in response to the driving signals. A device look-up table is stored in the microprocessor (10), the look-up table storing device codes identifying respective ones of the plurality of electronic devices and the driving signals associated with the respective electronic devices. An electrically erasable programmable read only memory (EEPROM) (30) is coupled to the microprocessor (10) for storing device codes, whereby the microprocessor accesses the look-up table utilizing the device codes stored in the EEPROM (40) to output a driving signal in response to an input from at least on key of the keyboard matrix (20). |
