<![CDATA[Pb.HUB will not connect. [Fixed]]]>Here is a copy of the Python,,Terminal, and Blocks. I erased and burned the firmware again. I looked and didn't see anything that was similar for trouble shooting. The miniscule amount of code I kind of understand, I don't see anything that stands out. Any help would be appreciated.

---PYTHON---

from m5stack import *
from m5stack_ui import *
from uiflow import *
import unit

screen = M5Screen()
screen.clean_screen()
screen.set_screen_bg_color(0xFFFFFF)
pbhub_0 = unit.get(unit.PBHUB, unit.PORTA)

label0 = M5Label('label0', x=102, y=101, color=0x000, font=FONT_MONT_38, parent=None)

pbhub_0.init_i2c_address(0x61)
while True:
label0.set_text(str(pbhub_0.read_status(0xFE)))
wait_ms(2)

I'll eventually come across something that I understand and it will sink in. Thanks again.

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.

  • 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

[Fixed] on Thu, 17 Aug 2023 01:16:58 GMT]]>@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.

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.

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

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

[Fixed] on Sun, 13 Aug 2023 20:32:20 GMT]]>@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.

[Fixed] on Sun, 13 Aug 2023 20:59:02 GMT]]>@ajb2k3 Oh, okay. I'm using the STM32 F030 and Uiflow V1. I'm using the Tough Core as well. What dosen't make sense is I had it working with blocks/code, then it stopped working. I tried different cables and ports with no joy. I even checked to make sure everything was plugged in. 😂.

@isoeek Update! I did nothing new or different, now it works. I guess this is "normal" as no one replied.

More of a case that there was no one around yesterday.
Is it the Mega328 Pb.Hub you have?

Which UIFlow are you using as I have one on my bench waiting to start a guide.
