Rolling Code receiver with the code visualized on the LCD display and RS232 serial transmission.
The software it`s realized in the MPLAB environment with the complete source.
You can edit the firmware upon your requirements and debug with MPLAB ICD2 or you can program your microcontroller. for the hardware realization you can take as example the previously scheme. The eventual alterations to the scheme must be made in the firmware too.

You can use the PIC Microchip microcontrollers that have on board the UART serial peripheral and the Capture Compare CCP1 module.

The plan receives the signal Rolling Code from the remote control, DECRYPTS it through the decrypt algorithm (first you must insert into the header of the program the MANUFACTURE KEY, supplied by the producer of the remote control) and allows the visualization on the LCD display. At the same time the complete code, and then the decoded part, are sent to the UART serial for being visualized on the PC, through the program Hyperterminal.

In this last case you can have (for example) an Access Control at a high security level, managed from your PC!
