How to use two ENV units with PaHUB (UIFlow)

liemph

I am new to UIFlow and need your guidance.
I managed to get temperature, humidity, and pressure for a single ENV unit directly connected to my M5Stack Fire (Port A) using the UIFlow.

Next, I have a PaHub and two ENV units. I connect the first and the second ENV unit to the port 0 and port 1 of the PaHub. I checked and tried to understand the Pa.HUB UIFlow example provided by the github (Pa.HUB.m5f). But still I could not understand how to proceed from the example to my goal, that is reading the two ENV units sequently. Please help!

@liemph Sorry, I have solved my problem by watching Lucas video on YouTube.

It is clear in explaining the PaHUB with UIFlow

Hi Guys
I have some further question, what about M5Stick C + ENV HAT + PbHUB connect together?

liemph

@jollawat There is no problem. The pins used for the Hat (ENV HAT) and the ones used for the grove port (PbHUB) are different.

@liemph I tried connect and program by UIFlow it but there are some error after run on screen said “please remove ENV hat” when we add PbHUB into list.

liemph

@jollawat I did not get it. Please post also your configuration (the connection between Stick-C, Hat and Unit) and your code.

@jollawat I do not have any ENV Hat, but I have a PIR Hat, and I tried to reconstruct your problem. I connected my PIR Hat and my PbHub (to Port A) of my Stick C. Then I connected my Light Unit to Port0 of my PbHub. Then I programmed using UiFlow to show the measurement results of both the PIR Hat and Light Unit. It worked well. Please see below, the code snapshot and list.

from m5stack import *
from m5ui import *
from uiflow import *
import hat
import unit
import hat

setScreenColor(0x111111)
pbhub0 = unit.get(unit.PBHUB, unit.PORTA)

hat_pir0 = hat.get(hat.PIR)



label0 = M5TextBox(13, 8, "PIR Hat", lcd.FONT_Default,0xFFFFFF, rotate=0)
label1 = M5TextBox(12, 63, "PbHUB", lcd.FONT_Default,0xFFFFFF, rotate=0)
label2 = M5TextBox(34, 34, "0", lcd.FONT_Default,0xFFFFFF, rotate=0)
label3 = M5TextBox(0, 83, "+Light Unit", lcd.FONT_Default,0xFFFFFF, rotate=0)
label4 = M5TextBox(26, 109, "0", lcd.FONT_Default,0xFFFFFF, rotate=0)


while True:
  label2.setText(str(hat_pir0.state))
  label4.setText(str(pbhub0.analogRead(0)))
  wait(1)
