@Saiyande
Good afternoon. I am from Russia and I am writing on this forum through a translator. So I apologize for my English. The M5Stack has an I2c encoder block(U153).There are 8 of them there
The actual ones are 16 buttons. I don't count the encoder buttons. I would like to make a module of 4 encoders and 8 buttons (2*4) in the dimensions of the Card computer. And the backlight on the RGB LED. And with the I2c interface. You have almost ready-made software. At the price, like the encoder block, I would buy for myself. You can also make a robot control panel. Or for example with a synthesizer modeler (U178)

The r-relay-unit looks promising. But how do I get power to the controller (M5 Atom, etc)?

thanks,

All the current offerings have either batteries, add significantly to the thickness, have pins/ports or are of significant cost just to use as a back cover.

We have a bunch of Core Basic deployed and took the guts out of the included Battery Bottoms and put tape on the gaps. Since they're always powered, we had a few batteries start to bloat and also occasionally something would short the pins, so gutting them was the easiest solution.

Not everyone needs batteries or extra expansion, and an extra plastic piece wouldn't cost much. I just though it would be nice to have just a simple piece of plastic cover... potentially with screw slots to aid in mounting

I had difficulty getting that module working, even on my AtomS3 Lite, the example Arduino code didn't work (and didn't even use all the connected pins). I had to use the schematic & datasheet to adapt AccelStepper to work with it. It would be nice if they moved the extra pins to I2C (and had them in the right state at startup so it actually works).

@ifantus Yeh, I'm the Mod of the communities.
They do visit the forums but they have been busy with travel.

lots of good things in feature forum!

I open mine up and cut mpu6886 out, now I use pins for anything I want without no issue

I could also just solder a grove connector to some cheap MAX232 boards from Ali and shrink tube them...

Most of my projects deal with RS232; M5Stack makes RS485 & CAN in Grove format, it would just be nice to have RS232 in that format as well to easily plug-n-play to their MCUs.

@holofloh thank you very much, I will try to study...

Thanks for the link; however I was looking for specific information on jtag debugging... (This device)

The official way to add comments only adds them to UIFlow (they are not exported into the python code)
You can right-click any block and select "Add comment", which enables a question mark icon on the block. Clicking that icon lets you add a comment in a bubble.
(I use those comments to describe why I did something specifically in UIflow/blockly.)

The unofficial way is the code block you show. Those comments DO get exported into the python code.
(I use those comments for things like describing variables usage and (re)configuration, stuff people would still need to know when using the micropython code directly.)

It would however be wonderful to have one official "Comment block" block that could be set to work either way, and set to start expanded or collapsed, etc.
I think it would be wise to retain "Insert into python code" or not as an option, as each type has advantages in different circumstances.

UIFlow through usb is not the problem of M5Stack it is the problem of the web browser creators. Usb over web is considered a security risk and not actively supported on most browsers.

There is talk of a new desktop version coming real soon as a video of it was on Twitter
