CFW for KSGER/Quicko STM32 Soldering Stations

[Polf]

There are no temperature jumps in version 2a.

im very pretty sure there is some error in pullup config, in ntc parameteres (beta), in ldo load sag, inproper wiring.

[Polf]

Maybe so. But logic suggests otherwise. I use the same connection for different firmwares. If the connection is incorrect, then the temperature jumps should not depend on the firmware. In fact, I see that there are jumps in firmware 21-10-06, but there are none in firmware 21-10-02a. How can this be explained? To avoid errors, I used different controllers and handles. I did not find any jumps in the C245 profile. Of course there are miracles, but I think that this is not the case.

[DavidAlfa]

Keep using 2a to make sure it doesn't happen.
The changes between 10-02a and 10-06 are minimal, just few tweaks related to the Oled and the main screen drawing.
The most important changes happened between 29 and 01 builds.
Sometimes there're sneaky errors that simply don't happen always. Just opening the station to update the firmware might be enough to open/close a defective connection.
Open the handle and check the wiring.
What happens when you remove the handle connector? The ambient shows -99.9, right?
What happens when you plug the handle again, but without any tip inserted?
You have to find the exact source of the problem.
Is It a Ksger v2? I will make a test fw showing some info in the screen to help troubleshooting the issue.

[Polf]

Open the handle and check the wiring.

I used multiple handles and the result is the same.
The same result is obtained with another user. https://radiokot.ru/forum/viewtopic.php?p=4102678&sid=c9cabbbf3bfd8abd65726caeb66a5b00#p4102678

Yes exactly.

What happens when you plug the handle again, but without any tip inserted?

See photo below.
Yes it is KSGER HW2.1s
David, I'm removing my question, I think I need to wait for messages from other users.

[DavidAlfa]

Try the new build (21-10-09).

Recently, I increased the initial system booting delay to ensure a stable voltage, as there was someone having issues with oled screen corruption.
There was a little hidden bug in the screen initialization, not updating another screen timer. Nothing happened until now because the old timings were close enough.
The boot screen forces a reset of the measures to show clean values in the main screen.
Now, due the increased boot delay, the bug appeared, so in certain conditions it could force the update without actual update from the ADC.
As it forces error reset to clear any bad readings caused by initial power-on noise, the combination of both seems what could be triggering the NTC error.
The code was updated, shouldn't happen anymore.
I couldn't replicate the issue in my station in any way, that's strange.

[Polf]

David, thanks. Now everything is fine, no temperature jumps occur. 

[DavidAlfa]

Thank you for testing, too
I realised something was wrong in my station because the tip initially read -40ºC, then slowly recovered after few seconds.
My amplifier has a minor issue where it causes a small drift, so with a cold tip the ADC usually reads 360.
A negative value means the ADC value was less than that, probably 0, in other words, wasn't being updated before exiting the boot screen.
Since the only recent change was the boot delay, I followed that path... These sneaky bugs in the code take a lot of time! 

[Tugo]

I found a bug and I don't know if I just didn't read something so I apologise if I didn't read something.
My hardware is Ksger v2.1 with latest version sw 21-10-09.
When showing graph and changing temperature it shows temperate on the middle of the screen but it will never disapear from the screen. Even after clicking on the main button. Only long press to get into menu and back will remove it.
Is that bug only on my HW?

[groff]

The same thing on my HW2.1 with 01-10-2021 sw.

One proposal from me. Very often I forget to select tip after changing. I think it will be useful to see "select tip" togather with icon "no tip" on display and select it by simple rotating knob.

[DavidAlfa]

Sorry, I can't test everything everytime.
Nothing serious, caused a while ago when I fixed a small bug that was continuously triggering screen refresh.
Fixed, uploading new builds.

gorff, if I do that, changing the temperature from the error screen won't be possible.
You can change the tip at any time.

[Tugo]

David, it is not a problem that you make mistakes. We all do. That makes you human 
I didn't check yet and should be tested later today.


EDIT: I just tested and the bug (or the feature  ) is gone. Now it works as it should. Thank you!

[Tugo]

David, is there a way to sort tips by the name? When I want to pick an inserted tip I need to scroll round to see where it is. Question is in a form if it is possible to please put it on ToDo list 

[ricktendo]

Don't know if this has been asked before, but would it be possible to add a pre-compiled list of tips that can enable/disable similar to the original fw?

Hmmm. I already had an efficient bubble sort algorithm I made for other project, so it was easy.
Tips will be automatically sorted on any addition/deletion/modification, keeping track of the current tip being used.
I also added a new feature: Now you can also select the working tip from the tip list screen by long-clicking over it.
This make it easier when you have a lot of tips in the system.
Updated builds

I don't see much sense on that, and complicates things. There're 40+ T12 types. It's okay as it is.


The purpose of having only one tip by default is to calibrate it, then the new tips will copy that calibration and be more or less close.
I'd add more tips, but it's stupid for a simple reason: You'll have a lot of completely uncalibrated tips, every single one requiring manual calibration.
It's much easier to simply add or copy an exiting calibrated tip and write 4 letters.
Currently, enabling/disabling the tips cannot be easily done. ToDo, maybe in the future.

[Tugo]

THANK YOU David!
I will test it later today and get back to you.

Regarding adding all the tips... I agree with you and I believe that your way is better because you can save the tip under the name you prefer or even have "top 5" tips you wish to have on the top (by adding '_' before the name) or even have multiple "same" tips with adding numbers or any other character by knowing which is which.

All I needed was sorting 

[wickated]

ksger "tip list" is just a marketing feature to force you buying more tips 
and not to program manual tip adding and keyboard entry.

[DavidAlfa]

Caught a small bug in the system menu, returning from NTC or Reset menu would restore a wrong position.
Fixed, I very rarely use these menus...

[wickated]

never mentioned it cuz it was released with menu flush ram saving feature.

i have some question . are 2.x and 3.x pin compatible ? could it be possible adding spi screen module wiring only data pins for creen

[DavidAlfa]

Nope, v3 is v2 and v3 is v3. The schematics are very different.
And what gives? The display is already very fast. You won't get anything by doing so.
I'd understand it if it was slow as with the factory firmware, giving only 10-15fps being optimistic.
But it's capable of 90fps with i2c screens, so what's the problem?
Thanks for reporting the bug...

[Tugo]

I like sorting very much 
All I did was a quick test and I can set "BC3" to " XXX" just to have it on the top as default.
I also test long push in the edit menu to set that tip and it works which is very good feature! 
Other tests will be done later or in the next few days and in case I get something weird I will tell you (well, I will let you know when I will stop doing all the test but I have a couple other things to work in our home).

This is something that could be changed but it could also be as it is. Under "Iron" changing "No iron" values are changed by 10 and not by 1. If I set it by mistake to 4096 I cannot get to 4090 directly. I have to go down to 300 and them go up to 4090. This was the same in the previous version but I forgot to write down.

[DavidAlfa]

Not important, anything over 3800-3900 is already a lot.

[wickated]

with i2c screens, so what's the problem?
Thanks for reporting the bug...

user tryed another screen module with ss1306 and if shows mess if wired to i2c. afair i2c screen bus is overcloked a lot here, so i guess plain spi should act wo any bugs.

i thought that if u didnt code menu ppostion return directly so its much complicated todo and shouldnt be bothered

[DavidAlfa]

You shouldn't use wires for high frequency signals.

I got a new Quicko today with a CHK (CKS?) 103 controller

Something is strange. Only the STM32 is connected.
