Pb.HUB will not connect. [Fixed]

  • I can't connect PbHUB V1.1 to Atom Lite or Tough.

    First check if pbhub is connected or not? Check whether the i2c scan device result is [0x61] or [97].

  • @pandian-nano Thanks for the suggestion and help. This is what is in the terminal.

  • I have lost track of how many times ive erased and downloaded the firmware. This is the last Terminal screen.

    I felt I was making decent progress at first. I have had so many failures now, I question the little bit I do know. Tried Uiflow V2 but Pb.Hub is not available.

  • Hi,


    Please check again and check the result

  • @pandian-nano Thanks. This is the out come. I looked up the Hex for 96 and I get 0x60. I believe I need to set init and/or set the new address. Is the answer as simple as using the Write Memory Data under I2C Master? Is the included block what I need to burn? I'm doing my best to learn this, but damn there is a lot to learn!

    I tried using this code and I had no change.

  • @IsoEek

    • Please check again and check the result 0x61[97]

    • If you get 0x61 result then your pbhub i2c address was changed from 0x60 to 0x61


  • @pandian-nano said in Pb.HUB will not connect.:


    I now get [97] and True. I just tried using digital and analog read. Both are working as expected. That was a really cool party trick! Where can I read more about what you walked me through. I obviously have no issues making bad code. I need to know how to clean up my own messes and how to debug. Thank you so much for the help. I appreciate it more than you know.

  • @pandian-nano Thank you. I have read through that several times and it makes no more sense than the time before. I'll eventually come across something that I understand and it will sink in. Thanks again.
