The RFEVAL1 is a hardware development platform designed to assist the engineer with a 鈥楲ow Power Radio鈥?/div>
Application.
This evaluation kit provides easy to build telemetry and data communications applications which may utilise
various hardware and software encoders and decoders and also with a variety of radio modules.
This enables the engineer to select the optimum radio module and antenna type for a specific target
application.
Primarily as a hardware development platform, the development boards are a transmitter PCB and a receiver
PCB, both of which can accommodate either AM or FM modules. An RS232 serial port is included on each
board to allow the designer to connect the boards to PC's and thus create more advanced, data
communication systems
When completed the system may be used as a complete radio system.
Three projects are studied in detail;
1.
Simple Radio Switched Relay
using Keeloq HCS360 encoder & HCS512 Decoder. (A hardware
solution)
2.
Remote telemetry switching
using Keeloq HCS360 encoder & PIC16C73 Decoder (a software
solution)
3.
Radio Data Communications;
Transmitting a data byte between two PC's
The boards are supplied part populated with a pre-tuned PCB antenna ready for use. The user simply
populates the PCB鈥檚 to the specific schematic diagram as per the project required.
