Intra-Board Communication

This file contains the necessary communications between the two sides. The PC appli-

cation needs to be informed of any updates relating to KEELOQ. As a consequence,

there are numerous places within the target application code that grab data and send

to the host controller. This code should be left untouched since it has no effect on the

actual data manipulation of KEELOQ.

SX1239

This is the receiver that the target uses for receiving demodulated data. It uses SPI

communication for its configuration. Please see the SX1239 data sheet for more

information regarding its numerous registers and settings.

NVM Mediator

The “nonvolatile” mediator provides access to the EEPROM where learned devices

and their settings are saved. The developer should access this using the find(),

write(), read() methods.
