Pb.HUB will not connect. [Fixed]

[IsoEek]

@isoeek Okay, I think I'm the cause of the fault as it's not working now. All I'm trying to do is run 2 maybe 3 mosfet dc speed controllers with a PWM signal from the Pb.HUB. If its not capable I'll use the EXT.IO2.

[ajb2k3]

Ahh power draw issues.

Try providing separate power to the devices but only connect the signal and GND pins to the PbHub.

[IsoEek]

@ajb2k3 I have a few Type C 2 Grove. I cant believe I didnt think about that. Thank you. I'll let you know how it goes.

[IsoEek]

@ajb2k3 Still no joy. 🤔This is from the terminal.

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

[pandian.nano]

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

[IsoEek]

@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.

Connected to Serial Port!

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.

[pandian.nano]

Hi,

Please check again and check the result

[IsoEek]

@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.

[pandian.nano]

@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

[IsoEek]

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

97

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.

[IsoEek]

@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.
