If factor is wrong on one of the platforms, then do a #ifdef PLATFORM_BEKEN

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

The problem seems not so easy to find:
The used factor works quite well on my device, a BK7231N, too. I only once had a 7 seconds old value, it's 3 to 5 seconds usually.
I'm on a business trip next days, so I can only try some untested changes to get closer to the source of the problem.
@divadiow if you can change and recompile the code, could you try with 20 or 25 instead of 17 for BEKEN (meaning a resulting factor of 2 or 2.5)?
Or you might switch back to the "nop" lines from the "old" version before which seemed to work at least slightly better than this one.

While thinking on it: I had problems and didn't get the sensor working on other pins than uart pins. And you are using PWM pin.
Stupid idea, but maybe timing differs if using different pins?
As I said, can't test for now.

indeed.

will have a play with diff pins

Actually, maybe that CB3S test should be ignored as I'm using a 5.1k resistor to pull up. I do not have any 4.7s to hand. Could that make a difference?

I don't think a 5.1k pull up should be a problem...

I just tried to make a special "test version" to address the timing problem (if this is the issue).
https://github.com/openshwprojects/OpenBK7231T_App/pull/1296

Idea: use "startDriver DS1820 <factor>" to directly use a factor.
The command "startDriver DS1820 9999" should do an automated test of the factors - starting with a value "10" and increasing it by 2 every 2 minutes.

So I hope you will be able to find a matching factor in the log (when more/all readings are going well ).
Then starting with the factor found I hope for a working driver for the sensor.

Added after 1 [hours] 14 [minutes]:

... and I ordered a cheap logic analyzer, so I will hopefully be able to check the real timings on the lines in the future.

that's cool. thank you thank you. I'll try new stuff asap. Just juggling a lot of work and distractions with other devices.

@DeDaMrAz asked me if I had one of these a while ago, so I got one https://vi.aliexpress.com/item/1005005357814678.html - not yet opened packet

but also, shouldn't datasheets have all the timings info?

I didn't want to wait too long and ordered one on Amazon for an "astronomical" price of ~ 8€

My guess is, that the generated timing doesn't work.
So if e.g. there should be a period of 10us from the datasheet, but the code will be wrong and sleep of 1us is in fact lasting 1.8 us, every signal is 18us.
And consecutive times which are 1.8 times too long may luckily work, but will usually not.

So, my suspicion is, that the timing is wrong, because the coded "usleepds(r)" which should last ~ r us, is in fact not working as expected.
And I hope the logic analyzer will show the actually used timing, so I can adjust it.

>>21164744

ok. i think I understand. interesting

Added after 5 [minutes]:

is there a risk that the timings will differ between clones/genuines/fakes etc and there'll always be a report from someone with x device that the sensor is off or not consistent in its reading interval?

I don't think so, I never had that trouble with any of my sensors (on ESP boards until now) and I'm quite sure they are not genuine ones.
Also I could see the same sensor making trouble with Beken working well on other devices, especially the W800 seems rock solid here. Getting a reliable timing source seems the solution.

well that's really annoying. the character limit on my long post wiped out all my updates so I saved what I did have available on screen as a single file. That single file is missing the content of all the spoilers where the logs were. anyway. the sweet spot was BKfact 18

Added after 1 [hours] 20 [minutes]:

but with the Maxim DS18B20 there are no hits (0 C though) until ages into BKfact 16 (which lasts 10 mins+) (DS1820 Temperature: -1.26 C (read 707 secs ago)

and I'm at BKfact 24 now with no readings yet

Out of curiosity, how much PowerSave affects the readings ratio? You should keep a total number of CRC matches and mismatches.

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

Lines where Read CRC equals calculated CRC: 0
Lines where Read CRC does not equal calculated CRC: 95

so, powersave makes all the difference

I finally found some time to investigate the resulting timing with the logic analyzer.

It seems impossible to get a decent "usleep" working for small and large arguments.

Looking at the test-firmware with "BKfact" to try to find a working number e.g. BKfact=17 will result in

Code: text Expand Select all Copy to clipboard
OWTimeH (should be 480us) 248us --> reset will usually work, but not inside specs !!! OWTimeA (should be 6us) 9us OWTimeE (should be 9us) 12us --> reading a bit is 6 us late (3 from A and 3 from E) might work, but not guaranteed

So I ended up in defining 3 versions for "short", "medium", and "large" times to wait and used "giedriuslt"s ideas of defining critical sections for the timing.

Also introducing a correction factor if powerSave is used, it works o.k. for me now even with "powerSave 1"
Maybe @divadiow you want to try the new version from PR #1296 (no more BKfactor present)?

My tests with the long-awaited sensor.
BL602, sensor from aliexpress for a few cents on pin 17.
startup cmd:
backlog startDriver NTP; ntp_setServer 217.147.223.78; ntp_timeZoneOfs +03:00; powersave 1; startDriver DS1820

Trusted device readings

Readings differ significantly.
There is one error in the console for more than 100 CRC measurements.
Sensor quality or?

If CRC is shown as correct, the readings should be highly likely the ones transmitted by the sensor.

If they differ very much from other sources, it could be quite some reasons:

The code doesn't work well, e.g conversion is not finished when we request the temperature

the sensor is read too frequently (reading will heat up the sensor a bit)

The two sensors (with different readings) are not close enough (so e.g. if I see the image, you might retry with the DS1820 connected with a longer wire connection, so that the sensor is not so close to the module)

The sensor really reports this (wrong) values.

Do you have the possibility to check the sensor on another device, especially with another code (e.g. an ESP32 with Arduino).

Changed the installation, wires from the Arduino socket/pin for easy replacement of sensors, there are about 10 of them. The readings are more correct, but why does the sensor on the board give such incorrect readings - radio interference on the sensor crystal? I'll check with a thermal imager later.
Now the question is - how to get data from the sensor in the script and via Mqtt

P.S.
again:
setChannel 7 DS1820
publish sensor_temper $CH7
delay_s 20
goto again
It doesn't work, I get 0

@max4elektroda

Can you please elaborate a bit on the usage of this driver? I've been playing with it today and I got some results that are mixed and inconsistent. Must note that I am using DS18B20 sensor which I think should be supported and the latest build 1.17.666 atm.

My reading vary from 3 to 90 seconds and I started the driver with

startdriver DS1820 8

A bit more understanding of the "factor" would be nice.

Thanks!

Can you please elaborate a bit on the usage of this driver?

I'll try, but in fact there is not much to do beside defining the pin and starting the driver.

There should be no difference between DS1820 and DS18B20 here.

The most challenging part was, and obviously still is, getting a working timer/delay for the OW protocol.
The "factors" are not more than a leftover of my tries to find a working "usleep" for this.
I tried to implement it according to the implementation in the DHT driver with loops of a number of "nop"s.
A first try find the number of nop-lines needed was to do a known number of "usleeps" and compare the time to the xtic-derived time - calculating how much this differs to give an idea of how to find a better implementation. I also played with kind of an automated fixing (the "factor" written was used to alter the usleep implementation).
I made a special test version in a PR where a factor could be given with the start of the driver, but this was only for testing (the first verion of PR #1296).
And it didn't work with all devices ...

In the end I hoped I had a working version, but couldn't test with all boards.
Especially Beken turned out to be tricky, I ended up in defining three "different" usleeps, depending if the time to sleep is "short" (up to 10us) "medium" (~50us) and "long" (hundreds of us, as e.g. used in reset).

The log seems to show, that timing is not working, especially only "ff" means, the sensor doesn't send data or we are "reading" the bit to late, so even 0 is read as 1.

Which module are you using?

Back to the original topic

Online builds do only work, if the SDK is prepared to allow the changes.
E.g. you could easily add charts driver to Beken platform, but for W600/W800, LN882H and XR809 you would need to change the makefiles inside the SDKs.

I propose to overcome this by moving this part of the Makefiles to the app repository and make an "include" in the SDKs.

So you can alter the makefiles inside the app repository without touching the SDK.

Made PR#1362 for this, which will need to apply the PRs to the SDKs to actually work...

I made a new folder "platforms" with a sub folder for every platform (atm "empty" for Beken and BL602).

So e.g. for W800, the (unchanged) Makefile is copied (or better moved) to "platforms/W800/Makefile".

The makefile in the sdk ("app/Makefile") now is very short :

Code: text Expand Select all Copy to clipboard
include ../sharedAppContainer/sharedApp/platforms/W800/Makefile

@max4elektroda thx, so what is the order and which PRs should I merge now to get both Makefiles change and charts changes fully working?

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

PR#1362 will just add the new folders and makefiles to the app repository.
This should be the first to apply - it will only prepare for the SDK changes but actually don't affect the builds.

Then, one after the other, the PRs for the SDKs will make the change "work" for they will alter the SDK makefiles to include the new ones.

But this will actually NOT enable charts, for I made a copy of the actual Makefiles (not including charts driver).

Personally I would prefer to make changes to the makefiles content in a later PR (after this one proofed to work).

So now, per SDK PRs?

Yepp, thats the idea

To actually make charts working on W800 we would also need changes to allow a "subset" of general driver code to work with "OBK_DISABLE_ALL_DRIVERS".

Maybe you could take a look to this commit?

https://github.com/openshwprojects/OpenBK7231...mits/732a6c5f468e952575de96304360231ab9a8dee9

If that's o.k. for you, you could merge https://github.com/openshwprojects/OpenBK7231T_App/pull/1360

I will then make a last PR to make changes to the (newly introduced) makefiles in the "platforms" directory

Added after 3 [minutes]:

Final question is, shall we also enable it in "obk_config.h" - and if, for which platforms?

Why work around OBK_DISABLE_ALL_DRIVERS instead of just disabling it? Does it bring any advantages?

Charts should be disabled by default, as it's very easy to enable them in PR if needed and things tends to break quickly with large OTA files. We already had problems because of that on Beken (LittleFS diseappearing) and on BL602 (too large OTA file).

There are quite some places we use this and I think I remember there were issues when simply removing it.
This will only allow three functions to work.

But since it's some time since I tried it, give me a moment to check again.

I think it would be better to fix old issues instead of introducing new define. I can help if that's needed. I've did some warning fixes yesterday and I may have some more time this or next day.

I just didn't want to deep dive into this ;-)

Added after 2 [minutes]:

That might simply be some missing sources in the makefile, which were not needed when disabling all drivers.
But we now have the possibility to resolve this much easier, if we don't need to change the sdk for this ...
