Pb.HUB will not connect. [Fixed]

[IsoEek]

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.

=== from m5stack import *
=== from m5stack_ui import *
=== from uiflow import *
=== import i2c_bus
=== import time
=== import unit
=== screen = M5Screen()
=== screen.clean_screen()
=== screen.set_screen_bg_color(0xFFFFFF)
=== pbhub_0 = unit.get(unit.PBHUB, unit.PORTA)
=== i2c0 = i2c_bus.easyI2C(i2c_bus.PORTA, 0x00, freq=400000)
=== i2c0.addr=(0x68)
=== while True:
=== print(i2c0.scan())
=== wait_ms(200)
=== wait_ms(2)

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

[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.

@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.:

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.

@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.
