3.2
Project Compilation
This step can be skipped if you only want to use the precompiled source code with default settings. If
not, compile projects for both the transmitter and the receiver. Detailed compilation instructions and fuse
settings are giving in the source code documentation.
3.3
EEPROM Image Generation
Allocate serial numbers and secret and shared keys for the system components. Then use the supplied
command line tools to generate one HEX file for every unit. The secret key for the transmitters should be
discarded after generating the HEX file. They are not needed and could compromise system security if
they get into the wrong hands.
Make sure that all transmitters that will be associated with a receiver have the same shared key as the
receiver.
Note:
1. The supplied tools are only meant for prototyping and evaluation. For full production use, a secure key
management infrastructure should be established.
