was to data packet encoding by ARM MCU

hello i am new to bladerf development i have some question . i am going to modify bladder_hosted architecture as a DQPSK transmitter. i try to add DQPSK and square root cosine filter module in FPGA vhdl code. the i wonder whether i can use ARM9 MCU to encoding/packet data before modulation. i have n...

Re: interface between bladeRF-XB and LCDmodule

You might need to share some block diagrams or rough schematics to better share the details of your goals. It's definitely not the "ideal" solution, bit I would imagine that if you're using an LCD with an HD44780-compatible controller, you could operate the LCD controller in 4-bit mode and then bit...

cause bladeRF cannot be accessed by to interface simultaneously ,i just close one of them.
then matlab can detect the bladerf.

interface between bladeRF-XB and LCDmodule

i need to use LCD module to display what the bladeRF(rx) received data. here is my solution,i get another LCD module (16*2 display) ,and connect it with the expansion board on bladeRF. my question is what should i do to control bladerf ?(PC or gnuradio? ) besides, i am new in FPGA so how do i mutilp...
