how to convert text extracted from a string via ESP NOW.

How to convert X to digital type integer?

I have error messages !

The Max value of the slider in Uiflow 1.7.2 does not work, whatever the value indicated, it remains at 100.
Would it be possible to have vertical sliders and the possibility of also modifying the color of the cursor?

I think my proble m is the same

I am in favor of an external 5 "or 7" LCD screen compatible with M5 cores

I did the test, it works with the red battery module link text
but I prefer the M5GO2, because it adds a port B and C

PaHUB does not work with CORE2, always the same message "name 'freq' isn't defined.
All these situations block any progress with M5stack products and add more and more frustration day after day.
Please, more testing before release to market.

It is very difficult to visualize the compatibilities of CORE with modules or UNITS.
From CORE2 it's very frustrating to see the many incompatibilities.
The designation "2" of certain products suggests that they are compatible with CORE2 and this is absolutely not the case, this adds even more frustration and purchases that are useless ...
This added to the lack of clear and detailed documentation may scare many people away.
Please clarify the situation quickly!

Unfortunately the GOPLUS 2 is not specific to CORE2 it is also the same problem with the FACE2 which is not compatible with the CORE 2 ... It is a big marketing error of M5STACK.
For a better connection I added small pieces of schotch under the PCB at the level of the screws on the GOPLUS 2.

Thank you for the details.
This will be a real problem for my robot which must evolve outside. I need to use something more evolved.
Do you think the TF mini Plus is compatible with a CORE2? Possible to program it with UIFlow, I haven't used micropython yet?link text

I have exactly the same error message with my CORE2 connected to a PaHub and an ADC module.
The ADC module works perfectly directly connected to port A of CORE2, but not through the PaHub
