CFW for KSGER/Quicko STM32 Soldering Stations

[AUTOMOTIVE SOLUTIONS]

i will try but not looking good just updated post ^ 

its not having any if it 24v psu no led

update r3 was open on the voltage regulator. voltage selection resistor must of been intermittent because every time i checked voltage rule one was at 3.3v now 7.4v 

just out of interest put 200 ohm in and we have 3.3v.will look tomorrow but think that's the end of the stm ect

[DavidAlfa]

Ouch... that sucks! Still you were lucky to not get full 24V!
What board is it? Do you have pictures?
I know simulation doesn't reflect real life, but that's all I have, here it works...
Proteus has SED1565 displays, that controller seems to be identical to the ST7565.

i have found a black pill here STM32F411 could i continue testing ?

[yelkvi]

I tried stm32F303 - didn't work. David said that it's a completely different chip.

[AUTOMOTIVE SOLUTIONS]

thank you will have to wait for new stm32f103 just really slowing things down

[yelkvi]

And I'm waiting for the displays. They are still in China. (by track number)
There are controllers for experiments. 2 pieces. No displays

[AUTOMOTIVE SOLUTIONS]

that's not good i just payed £16 for the lcd in the uk one form china £4. need to get a new stm32 fast lets see how much this will be lol

what version pcb did you get

should get it by 26 Apr.

[DavidAlfa]

OMG how is that? £16 for that cheap LCD?
Why not get a 2.4" OLED then, it costs the same!

There's no hurry -at least for me- , so do whatever you consider right. China option might be ok!
Nope, I don't think I'm spending more time with different mcus, just wait until your stm32 or my display arrives

[AUTOMOTIVE SOLUTIONS]

  i know i did think getting oled but would like to finish what we started and don't like to be beating. stm32 on order just £10 Bargain here 26th

i don't blame you not doing anymore mcu support lol

i am going to start on a pcb with supports for this lcd but before i start reinventing the wheel do you know of any open source pcb layout or should i just start from scratch thanks

Hello everyone, I made a board of V3.1s, but after I finished welding and burned the firmware, it was stuck in the boot logo.
Does anyone know the reason?Schematic diagrams and HEX files follow.thank you

[mastershake]

has anyone got the lcd screens working yet? i was debating on ordering a few

[DavidAlfa]

I don't have screen, people with screen have smokey stm32s...
Goes stand-by until the situation changes!

I turns out color and monchrome lcds have a subtle but critical difference when sending commands.
ST7565/SSD1306, etc, need the command arguments to be sent with DC=0, like any other command.
But color LCDs (ST7789, ST7735...) require the cmd with DC=0, then the arguments with DC=1.
Probably I've have mixed both at some point, not really sure.
Improved the code, should be working now unless some command is wrong, and if it doesn't, must be really close.
So I leave there a Ksger v3 ST7565 test build for anyone. If tested, please give feedback!
Contrast should be adjustable in the same menu entry.
Dimming options are removed, as the contrast will turn the display darker or lighter, not brighter or dimmer.

[mastershake]

ill have to order in a few to try out. ill see how fast i can get a few here. is there one color you recc over the others normally?

[DavidAlfa]

Check yourself, but personally, the one with white pixels over black background seems the best, gives that oled high-contrast look.
Haven't seen any myself, so the image quality could be crap and the pictures fake or too optimistic.

stm32 david 

0.7.1 working  stable clean flipped image
0.7.0 working stable clean flipped image  "best looking"
0.8 tries to initiate get a line for 1 second then blank

will post pics very soon

and i mean a clean image looks so good

[yelkvi]

Very positive news! Fine!

[DavidAlfa]

Nice! Also test:

test build we have no output

david i still have this screen here for you. i can not use 2 screens

got work will be back in 2 hours

[elninio]

Have anyone seen this Station disasasebled it looks like 2 Boards in one Housing

[DavidAlfa]

test build we have no output

What about this ones?
Now I'm, saving the lcd file too, I can't remember everything I did for every test!

[AUTOMOTIVE SOLUTIONS]

0.1 upside down contrast bad /have to look at a extrema angle
0.2 upside down contrast bad /have to look at a extrema angle

[AUTOMOTIVE SOLUTIONS]

0.1 upside down contrast bad /have to look at a extrema angle
0.2 upside down contrast bad /have to look at a extrema angle

0.3 was first time readable but a bit faint
0.7 best image bright

[DavidAlfa]

Yeah, now go into system settings and adjust contrast
But do they look the same?
Also: always make a full chip erase when testing different versions. The default settings might stay otherwise.

Translation request
To address any display orientation issues, specially with these DIY designs, I added new display options and moved them to a new screen for better organization:
The new entries needing translation are "DISPLAY", "X flip", "Y flip", "Ratio".
"Ratio" means "Voltage regulator ratio".

Code: [Select]

SYSTEM |-> etc
       |-> RESET MENU
       |-> DISPLAY |-> Contrast
                   |-> Offset
                   |-> X flip
                   |-> Y flip
                   |-> Ratio (Enabled only when using ST7565 display)
                   |-> Dimmer
                   |->  Delay
                   |->  In sleep

Attached v0.03, this version can tweak all display settings from the menu.
If it shows anything, even weak or washed out, that's ok, go into MENU/SYSTEM/DISPLAY and try different settings.
- Adjust contrast. You might also need to adjust Ratio, not sure if they're correlated.
- Adjust X and Y flip until the image orientation is correct.
- Adjust Offset until the image is centered.

I also made additional profiles for Ksger v1.5 & v3 and Quicko, for SSD1396 and ST7565 displays.

When it's finally working, report your settings and they'll be ready!

[AUTOMOTIVE SOLUTIONS]

we have a faint image on 18 and 500.i will fit the encoder now

now in a dark room trying

i do have eye stain but

contrast 40
