    How do I connect the Real Time Clock (RTC) pins on Blackfin? What if I don't
    want to use the RTC at all?


    For lowest power consumption, it is best to follow the advice of EE-281:

  • RE: How to write AD9361 FIR filter coeffs on no-OS driver?

    Are you generating RX filter coefficients and loading them into AD9361?

    >>Yes. setting RXFIRcoeffs below.


    AD9361_RXFIRConfig rx_fir_config = {
    3, // rx
    -12, // rx_gain

    Hi Rualri,

    Thank you for the response. Till now, we have not tried like this scheme. We want your support in finalizing our architecture along with any M/s Analog devices chip set in order to overcome any non-linearity and losses that may disturb the…

  • RE: Problems running examples in matlab by adrv9009

    Hello, there I solved it by changing the profile. Place the Tx_BW200_IR245p76_Rx_BW100_OR122p88_ORx_BW200_OR245p76_DC245p76.txt and followed suit. I wonder why I couldn't use the other profile that changes some parameters like the frequency of the device…

  • RE: Buffer pointers

    As you can see from lines 269 to 281 of this example -  github.com/.../ad9361-iiostream.c

    if you are continuously fetching samples from hardware by calling iio_buffer_refill(), then iio_buffer_step() and iio_buffer_end() also need to be called to get the…

  • ADRV9009 plugin profile errors


    I am using provided profile called  "Tx_BW400_IR491p52_Rx_BW200_OR245p76_ORx_BW400_OR491p52_DC245p76.txt". I am attempting to use this profile because I am interested in having the ORX BW at 400MHz and the sample rate at 491.52 MSPS.


  • Error Loading Profile using IIO Oscilloscope, ADRV9009

    Hi all,

    I'm trying to load a pre-made profile from the IIO scope: Tx_BW400_IR491p52_Rx_BW200_OR245p76_ORx_BW400_OR491p52_DC245p76.txt. When I try to load this profile the serial port spits out a lot of error messages and I'm unable to transmit or receive…
