FW1.6.4 and editor 1.0.12 totally broke my program, still can't upload but then again, why would I need to, it doesn't even run anymore, the python code gets screwed up.

I don't get to make an app anymore, all I do is running into stuff that doesn't work. It seems to me M5stack is suffering from what I call the "Yamaha disease" : keep spitting out new hardware without fixing the mediocre stuff they released before.
Well I for one am not jumping on that train anymore , I refrain from buying any more new stuff a la core2 and whatnot before the existing stuff gets fixed. (which I expect now, will never happen)

Hi, you should't use the variables "addr" and "data" as shown in the snippets
I think it should work like this:

Hi, surely everybody knows the MAX7219, but can I connect it to my m5stack core ? It uses SPI and I've been looking around, there are some libs on github and some posts here about SPI but I can't get it to work.

If it's possible at all, could someone point me in the right direction ?

@lukash616

This maybe could point you in the right direction (subject to improvement ofc.):

A fairly new user of m5stack here (and only talking UIFlow),

1. There is documentation, but often incomplete and unclear, hence not at all new user friendly (e.g. try finding explanation of the math blocks)
2. I experienced this (1.6.1) but luckily it got fixed rather quickly in 1.6.2
3. That is being investigated/fixed right now
4. I managed to crack a screen on a stickC, my own fault, but it is very flimsy.

My conclusion: I still have confidence in M5Stack, I think they are very willing to help and fix any problems. But the documentation really needs to be improved.

So I managed to get UIFlow running on a linux machine (a struggle in itself, I dare say) and... same result, it hangs while uploading via USB. It doesn't give me the syntax error, but it's stuck with the "Uploading..." indicator diplayed on the device.

Wel this problem still persists, I guess I was secretly hoping for someone from m5stack to shed a light on this matter. ;-)
Is there maybe someone who could try to reproduce this error with the desktop version of UIFlow ?

@world101
Hi, thanks for having a go at it.

As I mentioned before, with the desktop version the python file gets uploaded, but then I get the syntax error (when it should auto-start after the upload). After a manual reset and switch to app mode, the python file is on the device, I can select and run it on the core, it runs fine. I can run the py from and upload it via Thonny too without any problem. I've tried it on 2 devices, a black and a grey, I've tried different cables all with the same result.

With other projects the upload to the device also works fine. Is it because there something wrong with my .m5f ? Is it because its a little bigger, who can tell ? I really would like to have this issue solved before I officially share this project so people -especially new to m5stack- can atleast get it up and running without hassle.

@vkichline
Thank you, I'm glad you like it.

Once the upload issue is fixed, I'll share the m5f file, anybody then can easily change the color to their liking or infact modify it entirely if desired, there's most likely things in there that could have been done in a better way. (Feel free to point them out, I'm still learning)

@world101

Hi, I left it "uploading" for about 15mins, long enough to conclude it hangs I suppose.

You can find the m5f file here
(Bear in mind, I'm no coder, just a hobbyist)
