7.2.1 Microcontroller JB16
The functions of the JB16 are to handle the USB transactions, control the
baseband IC to receiving input data, and perform the overall system
control. The processed data is converted into USB report format and
sent to the host.
7.2.2 RF Transmission
The receiving RF signal will be down-converted into IF band for
de-spreading with DSSS scheme and ASK demodulation. The
demodulated data in serial packet format will be converted back to
parallel data and sent to the MCU for USB report generation.
