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

    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.

    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.

    ... 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.

    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.
    Helpful post? Buy me a coffee.

    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)?

    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

    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 ;-):

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

    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).

    Merged 1362:
    https://github.com/openshwprojects/OpenBK7231T_App/pull/1362
    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 ...

Topic summary

✨ The discussion focuses on creating custom drivers for OpenBeken (OBK) devices without requiring a local toolchain by utilizing online builds. Key challenges include integrating external libraries such as OneWire and DS18B20 sensor drivers, adapting timing functions (usleep) for precise 1-Wire protocol communication, and handling platform-specific differences across Beken-based devices (BK7231T, BK7231N, W800, LN882H, BL602). Contributors share code improvements, including porting OneWire implementations, refining delay loops with nop instructions, and introducing CRC checks to filter erroneous sensor readings. The DS1820 and DS18B20 temperature sensors are discussed in detail, highlighting their protocol similarities and differences, and issues with timing accuracy and sensor pin selection are addressed. The conversation also covers build system enhancements: restructuring Makefiles into platform-specific folders, enabling charts drivers, resolving conflicts with OBK_DISABLE_ALL_DRIVERS, and proposing a flexible pre-build script mechanism to override SDK files during online builds. This approach facilitates easier customization and patching without modifying SDK submodules directly. The group tests various hardware setups, sensor wiring, and power-saving modes, emphasizing the importance of accurate timing and CRC validation for reliable sensor data. Finally, improvements to the build and release process are discussed, including caching SDKs, selective SDK installation per platform, and troubleshooting simulator packaging in release artifacts.

FAQ

TL;DR: “Writing a driver straight on the OBK device is much more flexible than scripting” [p.kaczmarek2, #21095505]. In test logs 65 % of DS18B20 packets passed CRC on first try [divadiow, #21165112]. Follow the new pre-build override and chart drivers to patch and visualise data without local toolchains.

Why it matters: These tweaks cut build friction, expose sensor faults early and keep OTA binaries under the 700 KB safety limit.

Quick Facts

• DS18B20 range −55 °C to +125 °C; 0.0625 °C max resolution [Maxim DS18B20 datasheet]. • Typical OBK OTA image: 560–680 KB per platform [GitHub artifacts]. • Online CI builds ~8 min (six platforms, simulator) [workflow logs]. • Pre-build override path: platforms//override/… copied into SDK before compile [max4elektroda, #21254106].

How do I add a new OpenBeken driver without installing a local toolchain?

  1. Fork OpenBK7231T_App, add your .c file plus table entry in drv_main.c [p.kaczmarek2, #21095505].
  2. Commit; GitHub CI produces ready BIN/OTA zips for all chips [p.kaczmarek2, #21095505].
  3. Flash via Web UI or OBK OTA. No GCC, Make or SDK install needed.

Where do I turn a driver on or off for one platform only?

Edit src/obk_config.h and wrap the new #define in the platform section, e.g. #ifdef WINDOWS … #endif [p.kaczmarek2, #21095505]. The pre-processor then strips unused code so OTA size stays <700 KB [workflow logs].

What is the new “pre_build.sh” override hook?

Place a script at platforms//pre_build.sh. It runs after SDK checkout but before compilation, letting you patch or copy files into the SDK tree [max4elektroda, #21254106]. Example snippet: 
sh
cp platforms/BK7231N/override/sdk/.../BkDriverFlash.c \
sdk/OpenBK7231N/platforms/.../BkDriverFlash.c

Can I change RF/OTA partition addresses without touching the SDK?

Yes. Copy a modified BkDriverFlash.c (or any file) into the override folder; pre_build.sh copies it into the SDK automatically. No sub-module update is pushed [divadiow, #21252245].

How do I step-debug an OBK driver on Windows?

  1. Copy freeglut.lib, glew32s.lib, pthreadVC2.lib from obkSimulator/libs_for_simulator into your VS lib path [p.kaczmarek2, #21265130].
  2. Open openBeken_win32_mvsc2017.sln, set build target “openBeken_simulator”.
  3. F5 launches the simulator; set breakpoints in your driver file and watch variables live [#21095505]

MQTT shows stale temperature when my DS18B20 falls off – how to clear it?

Driver v1.17.** sets channel only after a valid CRC read; after 30 s without success it skips CHANNEL_Set so HA marks the entity unavailable* instead of replaying the last value [max4elektroda, #21295662].

What value marks an invalid DS18B20 reading?

The driver stores −127.00 °C (0xFF) internally, a Maxim-documented error flag. It is no longer published via MQTT to avoid graph pollution [max4elektroda, #21295662].

Edge case – my simulator zip sometimes missing from releases; fixed?

CI missed the file when jobs finished out of order. Workflow 1.17.759 adds needs: [build, build2] and a merge step so simulator and XR809 zips are always published [max4elektroda, #21280901].

How can I visualise voltage/current live inside OBK?

Install chart driver: 
ini
startDriver charts
chart_create 48 2 2
chart_setVar 0 "Voltage" axv
chart_setVar 1 "Current" axc
addRepeatingEvent 5 -1 chart_addNow $voltage $current
[max4elektroda, #21243725].

Does DS18B20 B-variant work?

Yes. The driver treats DS1820 and DS18B20 alike; family code 0x28 passes CRC exactly as 0x10 devices [max4elektroda, #21296761].

How often do DS18B20 reads fail?

In a 150-packet test 35 % failed CRC ( −127 °C) on a noisy pin, but <15 % after switching to UART pin and 4.7 kΩ pull-up [divadiow, #21158429].

Low-power mode affects timing?

PowerSave 1 stretches delays; usleep auto-factor raised BKfact from 17 to 20, slowing the 1-Wire slot to ~78 µs [max4elektroda, #21264263]. "NOP loops must be short or timing skews", notes the author [p.kaczmarek2, #21157011].
