Description:
|
This application note describes how to implement a KEELOQ stand-alone programmer using a Microchip PIC16F84A microcontroller.
The PIC16F84A is a FLASH microcontroller with 64 bytes of internal EEPROM that, in this design, is used to store the incremental serial number programmed into HCS encoders every time. All the other HCS configuration parameters are defined as constants in the FLASH program memory of the PIC16F84A.
