Hi,

Can you provide which GPIO are available at the IWR6843 ISK board ?

Also, some code for IO control of such ports ?

Thank you

  • Hi,

    Please review the board schematic.
    GPIO 0, GPIO 1 and GPIO2 are available.

    Regards,

    Hi Charles
    Can you provide some c code to deal with this IO ?
    I want to toggle a LED to be connected to these IO's

    Thank you

    Hi,

    Please download the SDK and go to path below for example
    ...\packages\ti\drivers\gpio\test\xwr68xx\main.c

    Hi,I'm using the IWR6843ODS-ISK or the IWR6843ISK boards using the BOOST board.
    can you provide which GPIO of the IWR6843 can be used for output ?
    GPIO_0/1/2 are occupied.

    output on which header?
    Please see Datasheet for Pinmux, then review your application to see which unused pin on the chosen header can be muxed as GPIOs.

    Hi charles.

    Thank you for the answer.

    I've asked for assistance in locating free io when the iwr6843 is mounted on the boost board.

    At the initial answer ,you mentioned that gpio0/1/2 are free, but according to schematics,they are connected to peripherals on the boost board.

    Please direct .

    Hi,

    The MMWAVEICBOOST board is an evaluation platform. The GPIOs readily available for indication & user switch is GPIO _1 and GPIO_2. GPIO_0 is available for use. if you need more GPIOs you will need to mux other unused pin to GPIO.

    Please let me know if this is helpful.

    Hi Charles,
    GPIO_0/1/2 on the IWR6843ODS-ISK are named as RADAR_GPIO_0/1/2
    RADAR_GPIO_1/2 are connected at the Boost board to TS3A5018RSVR com's.
    As i see, they aren't available.
    Do you agree ?
  • In reply to gil albo:

    I think i don't understand what you are trying to implement. How do you plan to connect the GPIO to the external device?

    Hi Again,

    my intention is to control LED through the available IO's.

    connect wires to the IO, and to external small circuit.\that contains the LEDs
