    Difference between blluetooth data rate and UART baud rate

    I am working on high-speed data transfer by bluetooth. As far as I know, the maximal data rate of bluetooth v2.1 EDR is 3 mbps. But the maximal UART baud rate is only 1382400 for the corresponding serial bluetooth module (such as HC-05). I wonder whether it is possible for the baud rate to reach...

    Using FT2232H in Sync FIFO mode for streaming out data

    I want to use FT2232H in fifo mode for streaming out data. The external altera FPGA reads the FT2232H at a fixed rate of 48kb/s. On my PC side, what I need to do is to continuously check the number of bytes in the transmit queue. If the bytes falls below 32, the program will feed 256 bytes using...

    Clocked process triggered by pulse signal (VHDL question)

    What I would like to do is to execute a clocked process whenever the rising edge of a pulse arrives. Here is my code: process (pulse, clk) variable newTrigger: std_logic:='0'; variable cnt: integer range -1 to 32; begin if rising_edge(pulse) then newTrigger:='1'; end if; if newTrigger='1' then...
