uPyEasy v0.3.0 released

[LisaM]

Version 0.3.0:

• Dxbootstate switched from server based to client-server based

• Changed hardware page from server based to client-server based, most processing on the page is now done by the browser.

• Database single/multi row caching

• Plugins optimized, bug fixing

• Memory optimization done: Mem debugging added, pre-loading protocol/plugin changed to JIT

• Memory optimization STM32

• Added AP mode to config

• Added missing unix dir's

There are significant database changes, best is to erase your firmware before flashing it with V0.3.0

Debug level can be set manually at startup, change the file boot.py content to
upyeasy.main(loglevel=0)

Loglevels:
0 = Debug + mem info
1 = Debug
2 = Info
3 = Warning
4 = Error

Hi Lisa,
I just downloaded the STM32 version of release v0.3.0 (dfu binary file) from Github releases page.
It started up all right, after a hiccup while it connected to ethernet, but after a short time (a few minutes) it gave the following errors....

Any ideas where it's going wrong for me?

Hi Lisa,
Following my previous post, I notced a new update was available in Github (d71b3d5) so I did a git pull to update my local upyeasy repo and rebuilt micropython-stm32, then downloaded it to my board.
Unfortunately I'm still getting similar errors, this time they seem to be triggered by accessing the Hardware page.

EDIT: After posting the above, I rebooted the board and now it seems stable!
I don't know what to think.
I'll use it a bit more and see how it goes.

Sorry, still getting problems.
This time all was stable until I clicked 'Submit' button at bottom of Hardware page, then I got...

Hi Andrew,

Looks like a memory issue, can you restart with upyeasy.main(loglevel=0)
That will tell us the memory free all the time.

Can you also goto tools/info? On the console a memory map should appear telling the memory allocation.

Cheers,

Lisa

OK, thanks for the pointers, I'll try them later, probably this evening.

OK, I reset the board and restarted uPyEasy with "import upyeasy", "upyeasy.main(loglevel=0)"
Now I get the GC MEM Free values, and a different error: "ValueError: syntax error in JSON".

Hi Andrew,

I just tried this and it's working at my stm32.
I think this is due to database changes, can you erase the stm32? (press and hold the reset button, press the user button until red en green are on and then let the reset button go).
Erasing also deletes the database, so if you have settings you want to keep/remember then save it first.

Cheers,

Lisa

Hi Lisa,
I think I must be doing something wrong with the erase procedure. I never get red and green together on my boards while holding the reset and the user button - I've waited over a minute. One one of my STM32 boards the red is lit while holding; on the other board no LED. When I release RST I get a quick flash of the green LED, but when I look in config there are still details there which I entered before, so it looks as if it is not erased.
My boards are like this

Help please?!

I have the same one.
With the micro-usb connector below the two buttons, press and hold the right button (the one with K2 written on the board). While you hold the K2 button, the leds cycle: only red on, only green on, red and green on, etc. Wait until both red and green leds are on, then let go of K2. The blue led should be going on and off marking the erasure of the stm32 flash area (not firmware!), while red and green are on. After a minute or so, the blue light goes off and the green on. Then press and hold the reset button (K2) again until only the green led is on and let go of K2.

Efficient, but complicated i have to admit...

Ps. if you want to see what has been changed after a git pull: git log -5 (5 last log entries)

Cheers,

Lisa

While you hold the K2 button, the leds cycle: only red on, only green on, red and green on, etc. Wait until both red and green leds are on, then let go of K2. The blue led should be going on and off marking the erasure of the stm32 flash area (not firmware!), while red and green are on. After a minute or so, the blue light goes off and the green on. Then press and hold the reset button (K2) again until only the green led is on and let go of K2.

Efficient, but complicated i have to admit...

Ps. if you want to see what has been changed after a git pull: git log -5 (5 last log entries)

Cheers,

Lisa

I'm beginning to think that both my boards may be faulty. With one board, pressing and holding K2 gives a constant red LED which does not change. On the other board, no LED is lit while pressing K2.
I had to repair both boards a while back because the USB cable had strained the micro USB sockets and made the connection erratic. It may be that some part of the connection is still not good.
Another thought - do you know of a way to download a "blank" file to STM32, similar to make erase on ESP32? I've tried googling but not found anything.

dfu-util -s :mass-erase:force -a 0 -d 0483:df11 -D upyeasy_v030_20180506_test_stm32-pybv3_1024.dfu

That should do the trick: first it will erase the STM32F405 and then flash the new firmware.

Hi Lisa
Thanks for the quick reply. I'll try that - probably tomorrow or Sunday.

You will be probably one of the first to try out the new REST interface, it will mark a departure from ESPEasy's web-based UI. ESPEasy does have way more plugins, but uPyEasy has a much better and modern architecture which is now benefiting us for switching to the REST client-server setup.
If you look at the pages.py file, you'll see some significant changes already including two new DELETE rest api's already active...
The client side for controller/device delete's is now different to, which you can see at controllers.html en devices.html
Going bootstrap is the next step...

Hi Lisa
I've come back onto this today after a break as my mum died recently.
I found the latest update on Github (cf2bca9) and updated it to my local repo (the new filesystem). Did sudo make ..... deploy for stm32 (Ali pyboard clone). First time I hadn't erased the flash so I went back and did that (I think I've got the hang of that now).
But when I do import upyeasy, upyeasy.main(loglevel=0) I get this...

I also tried import upyeasy, upyeasy.main() and got...

and again it got stuck.
I'm baffled - have you any ideas what might be wrong please?

Hi Andrew,

If you haven't done

Code: Select all

upyeasy.setnet(1,'A3','A4','<SOC IP ADDRESS>', '<GATEWAY IP ADDRESS>', '255.255.255.0', '<DNS SVR IP ADDRESS>')

then uPyEasy on STM32 will try to use DHCP to get an ip-address. However sometimes it just waits forever to get one and it never does end.

If you haven't used the setnet command, please try to use that. Just do a ctrl-c before this point and enter the setnet command.

It also might be a wiring problem, please check if some wires are not connected anymore.

Cheers,

Lsia

Thanks Lisa. I hadn't previously done upyeasy.setnet... so I did that this time and it went further, but eventually got stuck again. Here is the log...

I've checked the wiring and it looks ok to me.
Can you offer any more suggestions to debug this, please?
Cheers,
Andrew.

Hi Andrew,

If you haven't done

Code: Select all

upyeasy.setnet(1,'A3','A4','<SOC IP ADDRESS>', '<GATEWAY IP ADDRESS>', '255.255.255.0', '<DNS SVR IP ADDRESS>')

then uPyEasy on STM32 will try to use DHCP to get an ip-address. However sometimes it just waits forever to get one and it never does end.

If you haven't used the setnet command, please try to use that. Just do a ctrl-c before this point and enter the setnet command.

It also might be a wiring problem, please check if some wires are not connected anymore.

Cheers,

Lsia

Thanks Lisa. I hadn't previously done upyeasy.setnet... so I did that this time and it went further, but eventually got stuck again. Here is the log...

I've checked the wiring and it looks ok to me.
Can you offer any more suggestions to debug this, please?
Cheers,
Andrew.

Oh dear, I should have checked wiring better first time!
It turned out that one of the Dupont wire connections between the STM32 board and the Wiznet 5500 was slightly loose. When I replaced it with a new one, and tried again from the start (right back to erasing flash then doing make.....deploy) -- it's working, and I can connect with my browser!!
No sensors connected at present, I'll test further.

Hi Lisa,
If I go to the Controllers screen in the browser, and try to Add a controller, the screen just stays blank, with no list of controllers to select from. (I can still get to other screens if I click on their tab). Here is the log - nothing that seems very helpful!

Hi Lisa,
I see on Github that you've been hard at work on a new update (9ebffbd) of uPyEasy!! Thank you for all your effort on this project!

I'm still keen to get uPyEasy working on my STM32F405 AliExpress clones, or at least the one which still seems to work reliably.
So I updated my local repo and set about building the firmware.

Initially I had errors from a couple of "missing" files in the /unix directory (copy.py and types.py) which I was able to fix, also I needed to create new links for these into my micropython-stm32 file system before it would work.

uPyEasy then started up ok and ran for a short time. Some screens are working (MaIn, Config, Hardware - Hardware is much more responsive! But i did find some issues....
- uptime is a large negative number of days, and some hours and minutes, bit of a time-warp
- Controller page: I tried 'Add' but got a blank browser screen, and in the log a Critical exception OSError(2)
- Devices: I got the first bit, to select a plugin, but clicking Submit gave an error "connection reset" and in the log NameError ('local variable rererenced before assignment')
- Advanced: tried to change NTP, Submit gave a MemoryError. It seems to be gradually using up the memory while in use.

Please keep up the good work!! I'm really keen to have a working Ethernet device, as potentially it should be faster and more reliable than wifi. Is there anything I can do to help?

Cheers
Andrew

Several bug fixes later...
I have everything working on my side, the source has been updated to 000df1a. Please update your side and try again.

But.. i do have some of the same memory problems as you have. If running on a stm32, please run it using: upyeasy.main(loglevel=0) and keep an eye on the memory!
If the memory level drops to about 7-8K, then you might start getting memory errors due to memory fragmentation. Workaround is to do a single action, like adding a controller, and then reboot.
This is happening due to the new deepcopy's (although now replaced in some parts by ordereddict init's) which make things more reliable but also consume more memory. I need to do a second round of memory optimization to free up memory.
A memory map can be seen when clicking on tools/info menu in the browser, then on your usb console a complete memory map is appearing when running in debug mode!

I'm not going to able to fix the memory problems shortly, due to the fact that i'm back home to the good old USA for the next few weeks.

Hi Lisa,
Thanks for the update!
Yes, I'll try the latest update and monitor the memory. I'll try to look for things which decrease the memory a lot. (I do have the impression - it is only an impression - that memory is sometimes used while "nothing" is happening, no actions from the browser!)
As you're going to be away, can you suggest any strategy to help me narrow down where memory is getting used up? If I can do that, it may make it easier for you when you return.
Cheers
Andrew

Hi Andrew,

My biggest concern is the memory fragmentation due to constant creation/destruction of objects!
This is explained more in details here: https://docs.micropython.org/en/latest/ ... ained.html
The memory map mentioned in the post above is a great help to see how the memory is consumed over time, if you would take a look at these i would be very greatfull!

One of the things i’ve done so far is the DB cache, so it doesn’t create/destroy DB records as before for the most used DB tables anymore. Stuff like that can do miracles for ram limited systems like the STM32. The ESP32 has a bigger ram supply, so it doesnt happen there as quickly as with the STM32. But the STM32 has way faster response times for both I2C/SPI/UART and web calls, so for more professional systems the STM32 is prefered...

Cheers,

Lisa

Hi Lisa,
Thanks for that, it helps me to understand the problem better. The information you linked contains another link to a section about "the heap", which uses the phrase "when the object goes out of scope". Can you elaborate what this means in practical terms, with an example or two from uPyEasy if possible? It might give me a better understanding what to look for.
Cheers
Andrew

Hi Lisa,
I updated with the new version.
Running ok on start-up.
Made and saved some changes in Config. Free men dropped to about 17000 but recovered a bit. (Sorry I'm away from my computer so can't give you exact numbers or full log.)
Tried to go into Controller page. Free men plummeted! Down below 4000! Without even adding a controller. Upyeasy froze.

Looks like Controllers code is prime candidate for some GC memory collect statements?

I'm going to be busy for next couple of weeks so unlikely to be able to get much further till then.

Cheers Andrew.

Looks like I cannot read the analog inputs, is that correct?

the phrase "when the object goes out of scope".

Hi Andrew,

It means that the object is no longer used by the function, because the function ended. Objects are allocated inside the function and when the functions end, the objects memory should be released.

Cheers,

why not? Are you getting an input error or so?

Hi Lisa,
Welcome back on the forum!
Thanks for your reply, it helps, although I'm still getting my head around the basics of micropython/python - could you possibly elaborate on the difference between an "object" and a "function", or perhaps give an example of each within uPyEasy please?
BTW, I saw a thread on the Micropython forum recently about memory problems, don't know if you have seen it already. https://forum.micropython.org/viewtopic.php?f=2&t=4912

Hi Andrew,

This tutorial explains about Python objects and garbage collection: http://www.tutorialspoint.com/python/py ... bjects.htm
I saw the memory thread, haven't got to implementing it. I'm busy with something big.

Hi Lisa,
Thanks for that link, I'll study it and compare some of the code in uPyEasy.
Good luck with the something big!

If it all works, things will start to fly...
