Dear ugfx Team,

I hope this message finds you well. It's been a few years, almost a decade, since I initially worked on developing a speedometer for an electric vehicle, drawing inspiration from Tesla's design aesthetics. I wanted to reach out to share my progress and seek information about the ugfx Studio.

Here's a link to the video showcasing the speedometer I developed:

For reference, here's how Tesla's speedometer looks:

Over time, I've received inquiries both in the comments section of the video and on this forum regarding the source code. I am now working on making the code public, but it's currently in a bit of chaos. I'm in the process of reformatting it, and I had the idea of creating a code generator for designing speedometers.

In this context, I recalled there being a WYSIWYG editor from ugfx – the ugfx Studio. Could you please provide an update on the status of ugfx Studio? I'm considering developing a tool for my speedometer project, and I'm curious about the current state of ugfx studio.

Moreover, I'm sharing the current progress of my speedometer project [App (blubal.de)], and I plan to create documentation that will explain the details in a more comprehensive manner, similar to my master's thesis but not as extensive.

I appreciate your time and assistance. Looking forward to your response.

Best regards,

hi there was already a version in the download section. I used it to convert files into header files and include them into my project, there is this ugfx studio? i need it again

kind regards

No, that does not work!

February 12, 2017

I get the chars via Bluetooth, when i display that stuff in hex its definetly äüö.

February 12, 2017

and where can i found this offline converter? i was on the wiki page that linked me to that online converter. when i type in " " to "²" it does not include äöü

How am i supposed to use the costum range?

i cant enter a number

November 20, 2016

hey, i had the same problem as you.if you want to use 24bit color depth, you need 3 write cycles of 8 bytes. just look into the ssd1963 specs.

gdisp_lld_SSD1963.c

gdisp_lld_config.h

lol, thats just one call

September 30, 2016

Edit: Moved from here.

Hey Joel, today i wanted to improve performance by using gdispFillArc, but i discovered a bug.

gdispFillArc(x, y, r, 79, 80, color); will create a full cirlce

September 29, 2016

Yes its ugfx, and of course, i will share my code as soon as i think its ready for public.

Just look into this small example, which i am actually using to design the arcs: https://jsfiddle.net/m5o6pagh/
The same works for ugfx if you translate the code, i actually use a modified version of the drawline function to put the pixel. This leads to some double drawing, becouse i use it excessivly to create a closed arc, but i will use the draw arc function soon to avoid this. To prevent that the numbers or the lines are overdrawn i use a "clipping map". It is just an bool array of the display size which i am using to make a lookup.

I hope i could give you a small image of the process, i use a lot of gimp, javascript and imagination to design this.

September 28, 2016

im currently developing such things for my master thesis

September 23, 2016

Hi, have you tried it with my gfxconf.h? It works with the provided one from you , but it will crash with mine.

EDIT: Figured out that #define GWIN_NEED_CONTAINERS TRUE was the reason for THAT problem with the demo just add it to the conf and it will freeze during init process

Kind Regards

Sry, heres a smaller one mini.zip. Its the project Folder from my chibios workspace. In my previous upload i have my whole workspace with the gentle note that just the test.c file is relevant since i commented the the other stuff out from beeing build.

September 20, 2016

workspace26.zip

Here you go

September 20, 2016

Thx for your response Joel, its just the test.c file.

This Topic is closely related to my other topic: https://community.ugfx.io/topic/454-weird-behavior/

One of the problem is that i cant use the history function of the console. If it "exceeds the display" and it is not visibile it will crash.

For this Topic i wanted to use your example from https://wiki.ugfx.io/index.php/Console

to debug and show the strange behavior in an minimalistic example.

But theres another big failure, because it didn't work . And thats strange, becouse i already use it, but in this example it cant even initialize.

The Call

GW1 = gwinConsoleCreate(0, &wi);

will crash in gwin_wm.c

_gwinWMAdd

        if (gh->parent && (!(gh->parent->flags & GWIN_FLG_CONTAINER) || gh->display != gh->parent->display))

and leads to _unhandled_exception (infinite loop) in vectors.c from chibios

September 12, 2016

push, please help me!

if i use the gfileOpen function after a gwinShow call it wont work. the file discriptor gives me an error an the gwinShow will abort (probably it has something to to with the error from gfileopen)

On 28.2.2015 at 08:22, inmarket said:

This display seems extremely slow. I can see it filling the screen eg change the color scheme in the widget demo. This is surprising given that it is a parrellel interface. Compared to the Mikromedia-STM32-M4 board (non-plus) which should be very similar and several other boards which use SPI interfaces (which should be much slower) this display is a LOT slower. I am not sure if it by nature of the display controller, an issue with the CPU running much slower than what it should, or some other problem. Can you please look at it and see what you can find.

is there already a solution for this? im struggling with this too.

hi, ich added #define GFX_USE_OS_CHIBIOS TRUE and

#define GFILE_MAX_GFILES 30

i recognized the next strange thing, all demos run a way slower than in your videos:

and there as no code from me, simply the demo from you!

i increased the value, it didn't changed anything

June 30, 2016

the error occurs when

gfileOpen(MY_PLAY_FILE, "r")))

is called. but only if createwidget is called. the audio module runs without it

it must have something todo with the gwinImageOpenFile call, after that i cant open it

kind regards

Hi, i can call either create Widgets or gfxThreadcreate, but when i use both nothing or something random is happening, sometimes just a scratchy sound, sometimes a part of the picture is visible. These are snippets of some example code of ugfx.

Hi Joel, if #define GFX_USE_GTIMER TRUE is missing, i got the error just out of the box.

But i have another Problem now, i cant access the sd-card. I added #define GFILE_NEED_FATFS TRUE but then i get this:
