• RE: HMC987LP5E Eval kit no longer configuring registers with the USB to SPI interface card

    I've checked and this is not the issue.  I have probed the SPI signals individually at the eval card interface on a working and non working card.  The SPI signals appear to be the same voltages and speed but I cannot attest to the content.  It would…

  • RE: Default Interrupt assignement for ADSP 214xx

    Hi Peter,


    As mentioned in Table A-6, page no 963 of ADSP-214xx Hardware Reference manual, the default Interrupt routing for SP0I (SPORT0) is P6I and for SP2I (SPORT2) is P7I. It is indeed to be a documentation error in Table 11-12 (page no 600). Thanks…

  • RE: Microcontroller to ADSP 21469 ez-kit lite via I2C

    Hello,

    As there is no default programmable interrupt priority for TWI, you may need to assign it to any of the programmable interrupt. In the below code I have assigned TWI interrupt (selection code is 0x17) to programmable interrupt 0 (PICR0 [4:0]),…

    Hi JNoon,

    thanks for your reply.

    The circuit implemented is the following:

    The realized circuit differs from that in the figure for the following things:

    • The inductor chosen is 74438357082 by Wurth Elektronic ( 8.2uH RDC_max = 86 mOhm)
    • The output capacitance…

  • GPIO interrupt

    Hello!

    I have a basic question about the GPIO interface. I'm using a ADRV9361 SOM with the ADRV1CRR breakout board and I'd like to use one of the DIP switches (SW0) in my C application. The gpio file in /sys/kernel/debug already lists SW0 at gpio…
