Requirements

The Data Capture Demo requires that the modules:

  • FTDI chips Port B is in OPTO isolated mode
  • the FPGA Intel MAX 10 is programmed with the demo specific firmware

If the module is in initial delivery condition, FTDI chip Port B is set to 245 FIFO and different Firmware,
boot requirements are not meet, so all steps on this wiki page need to be taken.

      Parameter description:
      COM14 - COM port which is used for the connection.
      115200 - Baud rate which is used for the connection.
      1024 - Amount of K samples to read, minimum 64 and maximum is 1024.
      c:\temp\capture.txt - File name and path which specifies where to storage the data.

    1. 1 - Command to adjust for the modules gain, possible values are:
                 TEI0015 and TEI0016:    1 for a gain of 1, 2 for a gain of 2, 4 for a gain of 4 and 8 for a gain of 8

    2. Befor running the demo, in Visual Analog, fill into the Pattern Loader the ADC sampling rate of your module:
      TEI0015 - 2 MHz  / Resolution - 18 bit
      TEI0016-0x-08-C8A - 0.5 MHz  / Resolution - 16 bit
      TEI0016-0x-08-C8B - 1 MHz  / Resolution - 16 bit
      TEI0023 - 2 MHz  / Resolution - 18 bit

      This sampling rate is only changed, when the demo has been run.

      It is often necessary to fill in the value two times before it is recognized.
      In dependency to the language settings, 0.5 MHz is sometimes not recognized,
      try instead of the separation point (0.5) a separation comma (0,5) or without the zero (.5 ,5)
      In the graph section, one can check the present sampling rate

    3. In addition, the ADC resolution needs to be adjusted also. In the Input Formatter Box, press onto
      the small Button, and adjust in the new appearing window the resolution.

Quick test with a terminal program

  1. Figure out the correct COM port number for the AnalogMAX DAQ1 board
    1. Open the device manager.
    2. Open ports and identify the port used by the AnalogMAX DAQ1 as visible in Figure 10.

  2. Open terminal and set the parameters (example use for putty).
    1. Set the connection type to Serial.
    2. Set the "Serial line" to your above found COM port.
    3. Set the "Speed" to 115200.
    4. Use "Open" to start the connection.
  3. Type following character for the appropriate usage.
    1. "?" to get the ID (AnalogMAX DAQ1 will return "1", DAQ2 will return "2")
    2. "t" to trigger ADC capture into the memory - 1M samples.
    3. "." to get one ADC sample.
    4. "+" to get 128 samples.
    5. "*" to get 16*1024 samples.
