ABSTRACT:
The universal remote control system comprises data processor, input device including a keyboard and a keyboard circuit connected to the data processor, signal output device including circuitry for generating infrared light codes connected to the data processor means, a memory including a battery backed, non-volatile RAM only and no ROM for storing (a) a set of instructions and (b) a library of code data for enabling the infrared light generating circuitry to generate specific infrared codes, the RAM being coupled to the data processor, and a data coupling device including terminals coupled to the CPU for enabling new code data to be supplied from outside the system to, or retrieved from, the RAM through the terminals and the CPU.
The RAM in the ROM-less data processing means is loaded by carrying out the following steps: (a) disabling the central processing unit; (b) connecting a separate microprocessor system to said RAM; (c) transferring instructions and/or data to said RAM; and (d) re-enabling the central processing unit to enable the central processing unit to execute the instructions so transferred.
