A component designator only makes sense if you have the correct schematic.

Have the ezTimeLog example loaded up. It is printing lines at the bottom of the canvas, and shifting previously printed lines up, indeed just like a terminal screen watching serial output. I think I misunderstood the scrolling functionality as the ability to use buttons to go back through the history at the top that had already scrolled off the screen. I see in issue #24 you say "canvas.print creates a buffer in memory that stores every print until it has scrolled off the screen", so that's not the way it works - sorry for my confusion.

Indeed, creating menu items that don't do anything would be a possible solution. I tried that early on, but found that once the menu was drawn (or run), it merely sits and waits for buttons. I have not tried creating a function that does an .addItem, then runs the menu again, and run that function with an .addEvent. I'll give that a try as soon as possible. Is there a limit to the number of menu items, other than memory constraints? If I'm successful getting the "menu" to redraw, I'll let you know, and I guess I'll see what the limits might be!

Thanks so much, @rop, your work is very appreciated!!!

@ajb2k3
Hello，I can not get your code in this post.

You also need to tune the drives way down low as it causes to steppers to overheat

Oh, I see the 150mAh battery

GOOOOOOD!!!
Works fine for me!
tnx very much!

My case (Fire version) does not allow me to reach the internal connector from the outside.

I've ordered a grey "version".

@lukasmaximus said in Button Unit Issue testing help please.:

I have tested the blocks associated with the single button unit and they definitely need some work.
Button press c shaped block only allows for a single press or release and the jigsaw shaped block
when combined with an if condition it throws an error that btn0_wasReleased or wasPressed is not defined.
These issues will be resolved in the next update and hopefully some extra functionality added.

Yeh, I was getting the btn0 is not defined error.

I've just taken several goes to write the firmware (I think my W7 laptop to blame).
It kept getting stuck in bootloader mode and wouldn't leave.
Finially got it to program and reset after pressing the on/off button twice.

Hi, We will put on sale a new product named "Bus" which is aimed for developers to expand I/O.

And here's the difference between with all cores. Maybe help you.

@watson
No, there was no COM-Port. As if it is not plugged or turned wrong around.
But as told, now it is ok. And i am glad it is. I like the M5s very much.

I still think, the capacitor solved it. But of course i am not sure.

@kurthofman said in UIFlow : Units are not available:

I'm using M5 Fire with firmare 1.0.3 in Chrome.0_1547060740019_snip_20190109200528.png

The update sorted out a minor bug with the Unit box but the ones with the blue symbol over them are not working yet.

iIRC I seam to remember something on one of the Esp32 forums with a similar issue. I think it was something to do with bus clock speed issue. I think it was down to the clock being set to high for the psram.

@jpilarski said in issue with remote in 1.0.3:

Nice work on the adc, iic, and on adding more unit blocks. Unfortunately it looks like there are issues with the remote blocks. They look to be overlapping on screen and make it difficult to properly select remote blocks.

What web browser are you using to load UIFlow as it worked fine for me.

Hi

I managed to get connected with the following.

Hello,
Maybe, Graphic Block and Emoji Block are not working now...

sorry, heart rate unit now in uiflow have some problems, we will fix it within two weeks

@ajb2k3:

OK, I did not know that arduino was not fully supported. thanks. is m5go and m5fire a different product? I do not think so. where are the sources of the versions located if they are open source? or do you mean the binaries are free (I found them in the M5burner replease)

The espressif idf is a topic which I have too look deeper into.

All sources, documents and specs are found on github.

Git Hub
Some of the docs are a little out of date though.
some of the "grove connection" units are found on the seeedstudio grove website.

Ok, as I walk around, I found I could "Zoom out" to get the ok buttons.

@lukasmaximus said in m5flow version 1.0.0 : M5 Stick connection:

@ajb2k3 I haven't opened one up yet so I can't say for sure

I've just ordered one so will do a comparison when mine arrives.
