Hi, the problem is still there. Removing the wait block kinda of fix it but reading are inconsistent. Any fix?

Thanks

No prob at all.
I made sure the esp32 is installed and Arduino points to the right directory. After that this is the outcome:

Hi

Has anyone tried to compile in Arduino cc 1.8.xx the chess example?
I've just discovered it but it seems it doesn't compile with a list of errors ...

Any suggestions?

@ipodlux Found it!
in order to compensate the slow reading of the interrupt I moved the reading in the loop. It less less classy that the external function but now it reacts as it should.

Hi

I'm sure many have been through this.
M5Flow blocks used for programming graphics and commands: testing if the interpreter is enough to assemble mid-fast interfaces.
Example attached:
Q any way to pass priority to the buttons' trigger and improve response?

Kind regards

Hi

It did happened to me few times on new Sticks, it looks like the issue sometimes is the testing runtime used before shipping.
Try this:
If it doesn’t turn on connect it to your computer,
launch the uiflow firmware utility,
you should see the serial port listed (the serial port chip is independent from power supply and should work),
erase content,
burn with fresh firmware
Repeat if necessary and make sure battery is charged

Hi

If you have the misfortune to open uiflow on your iPad browser and wondered what to do with the amazing blocky script just created here is a few tips to make good use of the time spent (works on iOS 12.3.1):
1 don’t close the browser or refresh the page
2 select uiflow menu and then Save
3 on safari the screen changes to a json-like script
4 select all of it and in the contextual menu select ‘Share’
5 the pop up icons menu appears
6 choose ‘Save as’
7 select a location /folder you know iOS can access from its Files app (usually Pages, Numbers or other iOS friendly folder, avoid app exclusive areas)
8 save it
9 open the app Files
10 navigate to the folder
11 find the file and rename with the name you prefer plus a .m5f at the end
12 the script is now safe
13 if you get again to uiflow you can open the script from its menu (it is visible to uiflow now that you changed the file extension)
14 modify and save as above

Enjoy!!

Indeed, making a device obsolete after months it's not a good practice and won't look good on the 'brand'. 60$ in the bin...

Hi

I’ve noticed the new 1.3.2 has no longer support for the grey/white Stick. Is it temporary or shall we kiss goodbye to our little fellas?

Cheers

@mati Yes indeed, exactly like that!

I checked the new UiFlow 1.3.2 and now P2P is available via web OTA, thank you all. My post or query can be tagged as solved

Cheers
