@lishengkkk all it takes is a small stroke of the cutter and the track is cut cleanly.
I scraped off the white paint to get to the copper. So if needed a drop of solder and everything works as it did at the start.

@lishengkkk I only use UIFLOW, no need to change the code once the connection is cut

@ajb2k3 J'attends avec impatience la version Française. super boulot, félicitations

With the M5Paper, Uiflow displays Alpha M5Paper and not 1.9.2...

Thanks @felmue

The PaHUB solution on internal I2C 21/22 does not seem to be the right solution.
I only have to use two EXTEND I/O with two different addresses, but Uiflow only recognizes address 0x27.
Do you have an example of using EXTEND I/O with the I2C master functions of Uiflow without going through the declaration of an EXTEND I/O unit.
I only need the 8 I / O input and to read their status

an example of use would be very useful

I am limited in number of ports for my project, I have to use I2C with internal ports 21/22.
When I declare in Uiflow a PaHUB alone on 21/22, I don't get an error message. But if I declare in Uiflow a Pahub and an Extend i/o unit on the Pahub, I systematically get an error message on the CORE2 "Pahub unit may be not connected".
If I connect and declare the Pahub whith extend i/o on port A it works.
I need several Extend i/o, I have no other solution than the PaHUB.
I tried to modify the I2C address of an extend i/o (0x25), but Uifow does not recognize it, it looks for it on 0x27 (possible to change that?)
A little help would be appreciated

I am in the same situation...
Several products announced with Uiflow and still nothing for months!
I hope Uiflow 2.0.0 will change that.

I just tested, it works from France

@tomward I just tested, it works with 1.9.1

@mamtho

Concerning the additional I/O I use the EXTEND I/O modules, Provide a PaHUB if you need to use several.

For the inputs here is a solution with optocouplers:

For outputs, I've used this before:

@schlabbermampf You can delete the M5GO Bottom2 battery from your shopping list, it is reserved for CORE2 and you already have a battery in the M5Stack FIRE pack.

@m5stack Can you let us know when uiflow will be available for the ATOM Display? I bought this module several months ago and look forward to using an external LCD with Uiflow and the ATOM Display.

@schlabbermampf ATOM lite is not compatible with CORE M5stack modules. It is preferable to use a CORE M5FIRE or M5GO

@bschwahn ds18b20 very easy to use with https://github.com/stonatm/UiFlow-custom-blocks/tree/master/ds18b20

@timtimw Can you provide a screenshot, I tried to connect other I2C modules without success.
Thanks in advance for sharing

You can find some informations on the following posts.
For my part I abandoned the LM35 to use the DS18B20 and it works perfectly with UIFLOW

@atu Can be made a test with the example of the MQTT unit

With the new version UIFLOW 1.9.0 I finally have used my MQTT UNIT. But the limit of 4 subscribe strongly limits my project ... I hope this limit will be delete during a future version.
