5. Receive Side Program

The 8051F930 MCU on the RFStick transmitter board is factory-programmed with the stx_demo program. Since

the program is programmed in flash memory, it can be overwritten using a Silicon Labs Toolstick Base Adapter that

is part of the Si4010 development kit or can be ordered separately as well (P/N Toolstick_BA). The complete

stx_demo software project can be found in the example programs package of the Si4355. It is available at the web

The receiver prgoram configures and controls the Si4355 receiver chip via the SPI bus. The Si4355 receives the

packets transmitted by the keyfob, checks the preamble, the syn bytes and the CRC. If the packet is OK, the

program flashes the LEDs according to the button information in the status byte of the received packet.

6. Schematics

Schematics of the transmitter and receiver boards of the kit can be seen on the following pages. Complete
