send(packets)

Format the packets as a bytestream and send it to the FPGA and on to the LArPix ASICs.

start_listening()

Start listening for incoming LArPix data by opening the serial port.

stop_listening()

Stop listening for LArPix data by closing the serial port.

empty_queue()

Empty the incoming data buffer and return (packets, bytestream).
