ABSTRACT:
A dedicated hardware block in the form of a hardware bit coder device for generating IR/RF bit coding protocols. The hardware bit coder device is configurable to any user-defined frame length and single or multiple frame strings. The device can emulate substantially any desired bit coding pattern. The device uses a programmable signal shaping technique that eliminates the need to develop complex bit coding protocols in software. Using the hardware bit coder device of the present invention directly reduces the amount of program memory required by the microcontrollers to accomplish data decoding and also frees up the microcontroller resources for other purposes. The hardware bit coder includes a set of two pattern registers, one corresponding to a high data bit value and the other to a low data bit value. The particular pattern to be shifted out for transmission is defined by the particular data signal. Pattern transmission rate and period are selectable.
