Possible issue with Tab5 and UiFlow v2.3.1 - (i2c driver install error)

robski

try with analog value, delete get voltage block

on your original "tube pressure" example use raw analog value for start too

Hi guys

I tested M5Tab5 (running UIFlow 2.3.1) with all the units I have available and most of them worked ok.

Note: I also got the i2c driver install error, but it didn't cause I2C to actually fail.

GPIO units

SSR - ok

I2C units (bus speed 100k)

Env III - ok
Env IV - ok
ExtIO2 - ok
Color LCD - ok
OLED - ok
PaHUB - Env IV - ok

I2C units (bus speed 400k)

PbHUB - ok
4Relay - ok

Unit Gesture and AMeter did not work for me with either bus speed 100k or 400k. M5Tab5 seemed to hang in setup and a hard reset was required.

Thanks
Felix

@felmue - Thanks felmue for tube air sensor with your Tab 5 with UIFlow 2.3.1! So your UIFlow test program with the Tube air sensor connected to Port A successfully uploaded to the Tab5 and captured air pressure readings? If so, can you post a screen shot of your simple program you used to test the sensor with?

I wonder what is causing i2c driver install error to be generated.

I will give it another try with the suggestions robski made but if you could post your testing code that ran successfully that would great!

Hello @Kenzo

I think you might have misread my post. I do not have a Tube Pressure unit so I cannot test this case, sorry.

Thanks

@felmue Yep, I read that wrong... my fault...

Well I started doing the process of elimination and decided to compile a default blank Tab5 project in UiFlow v2.3.1 with no unit sensors and the i2c driver install error still occurred... See screen shots... So something else is trying to load the i2c drivers in UiFlow v2.3.1 for the Tab5 device and is having a problem installing it...

Question: Could this be a possible bug somewhere when it comes to Tab5 and the UiFlow IDE???

i'm getting the same i2c driver error on an Atom Lite, the error began following an erase but persists regardless of the UIflow2 version I attempt to refresh with.

Hello guys

I think that is what I wanted to tell you guys with my previous post. The i2c driver install error, which I also get, does not prevent most of my units to work properly.

Out of all my units only two did not work and two I2C units would only work after switching the i2c speed to 400 k.

In other words I do not think the i2c driver install error matters in regard with the Tube Pressure unit, which is not an I2C unit.

@Kenzo : do you have any other units you could try with your M5Tab5? Or any other core(s) you could try the Tube Pressure unit with?

Thanks
Felix

in my case i need to query an AIN unit, which is i2c...so this error is a total blocker.

@Kenzo as Ive said before try below: remove "get voltage" block and try your Tube Pressure unit with analog value only
