This application note describes the design of a
microcontroller-based KEELOQ
®
transmitter with
receiver acknowledge using the K EELOQ encryption
algorithm. This transmitter is implemented on the
Microchip PIC16F636 microcontroller. Descriptions of
the encoding process, the encoding hardware and
description of the software modules are included within
this application note. The software was designed to be
backwards compatible with an HCS365 dual
transmitter in terms of memory map programming. AN1321

DUAL TRANSMITTER OPERATION
Microchip Technology Inc. This firmware contains two transmitter configurations
with separate serial numbers, transmitter keys, user
values, counters and seed values. This means that the
INTRODUCTION transmitter can be used as two independent systems.
